DUPLEX & SUPER DUPLEX FLANGES: Duplex steel (ASTM A182 2205) is an extremely corrosion resistant, work hardenable stainless steel, whose microstructure consists of a mixture of austenite and ferrite phases. The most widely used grade for Duplex flange is 2205, due to its superior resistance to corrosion and mechanical strength. The designation “2205” is related to the chemical composition of this material, which features 22% of chromium and 5% of nickel. Super Duplex flange show an even superior strength and a higher corrosion resistance than standard duplex steel (and austenitic grades, of course). The main difference between a duplex and a super duplex grade is the addition of copper to the alloy (in addition to increased amounts of Chromium, Moly, and Nickel). The addition of copper gives Super Duplex Stainless Steel an improved resistance to hot chlorides and strong reducing acids, like sulphuric acid, compared to a standard Duplex grade. Whilst UNS S31803, UNS 32205 (duplex) and UNS S32750, UNS S32760 are standard designations, most manufacturers of superalloys attribute proprietary names to these steels (example UR52N+ is a Usinor/Arcelor Super Duplex steel, Ferralium, Zeron, Sandvik SAF 2205 22Cr, etc). NICKEL ALLOY FLANGES: Inconel® Flanges Inconel® is a family of austenite nickel-chromium-based superalloys. Inconel® alloys are oxidation and corrosion resistant materials well suited for service in extreme environments subjected to pressure and heat. When heated, Inconel® forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies. Inconel’s high temperature strength is developed by solid solution strengthening or precipitation strengthening, depending on the alloy. We offer flanges in the following grades: ALLOY 600 N06600 B366 (REF), B/SB 564, AMS 5665 B/SB 166 ALLOY 601 N06601 AMS 5715 B/SB 166 ALLOY 625 N06625 B366 (REF), B/SB 564, AMS 5666 B/SB 446 Incoloy® Flanges Incoloy® refers to a range of superalloys produced by the Special Metals Corporation group of companies. They are mostly nickel-based, and designed for excellent corrosion resistance as well as strength at high temperatures; there are specific alloys for resistance to particular chemical attacks (e.g. alloy 020 is designed to be resistant to sulphuric acid, DS to be used in heat-treating furnaces with reactive atmospheres and many heat cycles) We offer flanges in the following grades: ALLOY 800 N08800 B 366 (REF), B/SB 564, AMS 5766 B/SB 408 ALLOY 800H N08810 B 366 (REF), B/SB 564 B/SB 408 ALLOY 800HT N08811 B 366 (REF), B/SB 564 B/SB 408 ALLOY 825 N08825 B 366 (REF), B/SB 564 B/SB 425 ALLOY C20 (F20) N08020 A 182, B 366, B/SB 462, B/SB 564 B/SB 472, B/SB 473 ALLOY 330 N08330 B 366 (REF), AMS 5716 B/SB 511, B/SB 512 Monel® and Copper Nickel Alloy Flanges Monel is a group of nickel alloys, primarily composed of nickel (up to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. Stronger than pure nickel, Monel alloys are resistant to corrosion by many agents, including rapidly flowing seawater. They can be fabricated readily by hot- and cold-working, machining, and welding. Monel alloy 400 is a binary alloy of the same proportions of nickel and copper as is found naturally in the nickel ore and is therefore considered a puritan alloy. It is a very expensive alloy, with cost ranging from 5 to 10 times the cost of copper and nickel, hence its use is limited to those applications where it cannot be replaced with cheaper alternatives. Compared to carbon steel, piping in monel is more than 3 times as expensive. We offer flanges in the following grades: ALLOY 400 N04400 B366, B/SB 564, QQ-N-281, MIL-F-23509 B/SB 164 70/30 CUNI C71500 MIL-C-15726, MIL-C-24679 B/SB 151 90/10 CU-NI C70600 MIL-C-15726, MIL-C-24679 B/SB 151 Hastelloy® Flanges The Corrosion-Resistant HASTELLOY® alloys are widely used by the chemical processing industries. The need for reliable performance leads to their acceptance and growth in the areas of energy, health and environmental, oil and gas, pharmaceutical and flue gas desulfurization industries. The attributes of HASTELLOY® alloys include high resistance to uniform attack, outstanding localized corrosion resistance, excellent stress corrosion cracking resistance, and ease of welding and fabrication. B-3® alloy possesses outstanding resistance to non-oxidizing acids, such as hydrochloric acid and sulfuric acid. The advantages of B-3® alloy over previous B-family alloys are enhanced thermal stability and improved fabrication characteristics. The most versatile of the HASTELLOY® alloys are the “C-type” alloys. C-2000® alloy combines outstanding resistance to oxidizing media with superior resistance to non-oxidizing environments and represents a true performance breakthrough for chemical process equipment applications. C-22® alloy is particularly resistant to pitting and crevice corrosion; it has been used extensively to protect against the most corrosive FGD systems and the most sophisticated pharmaceutical reaction vessels. G-30® alloy has been very successful as phosphoric acid heat exchanger tubing and for other process components in the fertilizer industry. G-35® alloy was designed as an improved version of G-30 alloy in these applications. The high chromium content of both of these alloys make them the premier choices for strong oxidizing solutions and mixed acid pickling services.

DUPLEX & SUPER DUPLEX FLANGES: Duplex steel (ASTM A182 2205) is an extremely corrosion resistant, work hardenable stainless steel, whose microstructure consists of a mixture of austenite and ferrite phases. The most widely used grade for Duplex flange is 2205, due to its superior resistance to corrosion and mechanical strength. The designation “2205” is related to the chemical composition of this material, which features 22% of chromium and 5% of nickel. Super Duplex flange show an even superior strength and a higher corrosion resistance than standard duplex steel (and austenitic grades, of course). The main difference between a duplex and a super duplex grade is the addition of copper to the alloy (in addition to increased amounts of Chromium, Moly, and Nickel). The addition of copper gives Super Duplex Stainless Steel an improved resistance to hot chlorides and strong reducing acids, like sulphuric acid, compared to a standard Duplex grade. Whilst UNS S31803, UNS 32205 (duplex) and UNS S32750, UNS S32760 are standard designations, most manufacturers of superalloys attribute proprietary names to these steels (example UR52N+ is a Usinor/Arcelor Super Duplex steel, Ferralium, Zeron, Sandvik SAF 2205 22Cr, etc). CANGZHOU WILSON PIPELINE manufacture of flange fittings&pipes NICKEL ALLOY FLANGES: Inconel® Flanges Inconel® is a family of austenite nickel-chromium-based superalloys. Inconel® alloys are oxidation and corrosion resistant materials well suited for service in extreme environments subjected to pressure and heat. When heated, Inconel® forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies. Inconel’s high temperature strength is developed by solid solution strengthening or precipitation strengthening, depending on the alloy. We offer flanges in the following grades: ALLOY 600 N06600 B366 (REF), B/SB 564, AMS 5665 B/SB 166 ALLOY 601 N06601 AMS 5715 B/SB 166 ALLOY 625 N06625 B366 (REF), B/SB 564, AMS 5666 B/SB 446 Incoloy® Flanges Incoloy® refers to a range of superalloys produced by the Special Metals Corporation group of companies. They are mostly nickel-based, and designed for excellent corrosion resistance as well as strength at high temperatures; there are specific alloys for resistance to particular chemical attacks (e.g. alloy 020 is designed to be resistant to sulphuric acid, DS to be used in heat-treating furnaces with reactive atmospheres and many heat cycles) We offer flanges in the following grades: ALLOY 800 N08800 B 366 (REF), B/SB 564, AMS 5766 B/SB 408 ALLOY 800H N08810 B 366 (REF), B/SB 564 B/SB 408 ALLOY 800HT N08811 B 366 (REF), B/SB 564 B/SB 408 ALLOY 825 N08825 B 366 (REF), B/SB 564 B/SB 425 ALLOY C20 (F20) N08020 A 182, B 366, B/SB 462, B/SB 564 B/SB 472, B/SB 473 ALLOY 330 N08330 B 366 (REF), AMS 5716 B/SB 511, B/SB 512 Monel® and Copper Nickel Alloy Flanges Monel is a group of nickel alloys, primarily composed of nickel (up to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. Stronger than pure nickel, Monel alloys are resistant to corrosion by many agents, including rapidly flowing seawater. They can be fabricated readily by hot- and cold-working, machining, and welding. Monel alloy 400 is a binary alloy of the same proportions of nickel and copper as is found naturally in the nickel ore and is therefore considered a puritan alloy. It is a very expensive alloy, with cost ranging from 5 to 10 times the cost of copper and nickel, hence its use is limited to those applications where it cannot be replaced with cheaper alternatives. Compared to carbon steel, piping in monel is more than 3 times as expensive. We offer flanges in the following grades: ALLOY 400 N04400 B366, B/SB 564, QQ-N-281, MIL-F-23509 B/SB 164 70/30 CUNI C71500 MIL-C-15726, MIL-C-24679 B/SB 151 90/10 CU-NI C70600 MIL-C-15726, MIL-C-24679 B/SB 151 Hastelloy® Flanges The Corrosion-Resistant HASTELLOY® alloys are widely used by the chemical processing industries. The need for reliable performance leads to their acceptance and growth in the areas of energy, health and environmental, oil and gas, pharmaceutical and flue gas desulfurization industries. The attributes of HASTELLOY® alloys include high resistance to uniform attack, outstanding localized corrosion resistance, excellent stress corrosion cracking resistance, and ease of welding and fabrication. B-3® alloy possesses outstanding resistance to non-oxidizing acids, such as hydrochloric acid and sulfuric acid. The advantages of B-3® alloy over previous B-family alloys are enhanced thermal stability and improved fabrication characteristics. The most versatile of the HASTELLOY® alloys are the “C-type” alloys. C-2000® alloy combines outstanding resistance to oxidizing media with superior resistance to non-oxidizing environments and represents a true performance breakthrough for chemical process equipment applications. C-22® alloy is particularly resistant to pitting and crevice corrosion; it has been used extensively to protect against the most corrosive FGD systems and the most sophisticated pharmaceutical reaction vessels. G-30® alloy has been very successful as phosphoric acid heat exchanger tubing and for other process components in the fertilizer industry. G-35® alloy was designed as an improved version of G-30 alloy in these applications. The high chromium content of both of these alloys make them the premier choices for strong oxidizing solutions and mixed acid pickling services.

DUPLEX & SUPER DUPLEX FLANGES: Duplex steel (ASTM A182 2205) is an extremely corrosion resistant, work hardenable stainless steel, whose microstructure consists of a mixture of austenite and ferrite phases. The most widely used grade for Duplex flange is 2205, due to its superior resistance to corrosion and mechanical strength. The designation “2205” is related to the chemical composition of this material, which features 22% of chromium and 5% of nickel. Super Duplex flange show an even superior strength and a higher corrosion resistance than standard duplex steel (and austenitic grades, of course). The main difference between a duplex and a super duplex grade is the addition of copper to the alloy (in addition to increased amounts of Chromium, Moly, and Nickel). The addition of copper gives Super Duplex Stainless Steel an improved resistance to hot chlorides and strong reducing acids, like sulphuric acid, compared to a standard Duplex grade. CANGZHOU WILSON PIPELINE manufacture of flange fittings&pipes Whilst UNS S31803, UNS 32205 (duplex) and UNS S32750, UNS S32760 are standard designations, most manufacturers of superalloys attribute proprietary names to these steels (example UR52N+ is a Usinor/Arcelor Super Duplex steel, Ferralium, Zeron, Sandvik SAF 2205 22Cr, etc). NICKEL ALLOY FLANGES: Inconel® Flanges Inconel® is a family of austenite nickel-chromium-based superalloys. Inconel® alloys are oxidation and corrosion resistant materials well suited for service in extreme environments subjected to pressure and heat. When heated, Inconel® forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies. Inconel’s high temperature strength is developed by solid solution strengthening or precipitation strengthening, depending on the alloy. We offer flanges in the following grades: ALLOY 600 N06600 B366 (REF), B/SB 564, AMS 5665 B/SB 166 ALLOY 601 N06601 AMS 5715 B/SB 166 ALLOY 625 N06625 B366 (REF), B/SB 564, AMS 5666 B/SB 446 Incoloy® Flanges Incoloy® refers to a range of superalloys produced by the Special Metals Corporation group of companies. They are mostly nickel-based, and designed for excellent corrosion resistance as well as strength at high temperatures; there are specific alloys for resistance to particular chemical attacks (e.g. alloy 020 is designed to be resistant to sulphuric acid, DS to be used in heat-treating furnaces with reactive atmospheres and many heat cycles) We offer flanges in the following grades: ALLOY 800 N08800 B 366 (REF), B/SB 564, AMS 5766 B/SB 408 ALLOY 800H N08810 B 366 (REF), B/SB 564 B/SB 408 ALLOY 800HT N08811 B 366 (REF), B/SB 564 B/SB 408 ALLOY 825 N08825 B 366 (REF), B/SB 564 B/SB 425 ALLOY C20 (F20) N08020 A 182, B 366, B/SB 462, B/SB 564 B/SB 472, B/SB 473 ALLOY 330 N08330 B 366 (REF), AMS 5716 B/SB 511, B/SB 512 Monel® and Copper Nickel Alloy Flanges Monel is a group of nickel alloys, primarily composed of nickel (up to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. Stronger than pure nickel, Monel alloys are resistant to corrosion by many agents, including rapidly flowing seawater. They can be fabricated readily by hot- and cold-working, machining, and welding. Monel alloy 400 is a binary alloy of the same proportions of nickel and copper as is found naturally in the nickel ore and is therefore considered a puritan alloy. It is a very expensive alloy, with cost ranging from 5 to 10 times the cost of copper and nickel, hence its use is limited to those applications where it cannot be replaced with cheaper alternatives. Compared to carbon steel, piping in monel is more than 3 times as expensive. We offer flanges in the following grades: ALLOY 400 N04400 B366, B/SB 564, QQ-N-281, MIL-F-23509 B/SB 164 70/30 CUNI C71500 MIL-C-15726, MIL-C-24679 B/SB 151 90/10 CU-NI C70600 MIL-C-15726, MIL-C-24679 B/SB 151 Hastelloy® Flanges The Corrosion-Resistant HASTELLOY® alloys are widely used by the chemical processing industries. The need for reliable performance leads to their acceptance and growth in the areas of energy, health and environmental, oil and gas, pharmaceutical and flue gas desulfurization industries. The attributes of HASTELLOY® alloys include high resistance to uniform attack, outstanding localized corrosion resistance, excellent stress corrosion cracking resistance, and ease of welding and fabrication. B-3® alloy possesses outstanding resistance to non-oxidizing acids, such as hydrochloric acid and sulfuric acid. The advantages of B-3® alloy over previous B-family alloys are enhanced thermal stability and improved fabrication characteristics. The most versatile of the HASTELLOY® alloys are the “C-type” alloys. C-2000® alloy combines outstanding resistance to oxidizing media with superior resistance to non-oxidizing environments and represents a true performance breakthrough for chemical process equipment applications. C-22® alloy is particularly resistant to pitting and crevice corrosion; it has been used extensively to protect against the most corrosive FGD systems and the most sophisticated pharmaceutical reaction vessels. G-30® alloy has been very successful as phosphoric acid heat exchanger tubing and for other process components in the fertilizer industry. G-35® alloy was designed as an improved version of G-30 alloy in these applications. The high chromium content of both of these alloys make them the premier choices for strong oxidizing solutions and mixed acid pickling services.

DUPLEX & SUPER DUPLEX FLANGES: Duplex steel (ASTM A182 2205) is an extremely corrosion resistant, work hardenable stainless steel, whose microstructure consists of a mixture of austenite and ferrite phases. CANGZHOU WILSON PIPELINE manufacture of flange fittings&pipes The most widely used grade for Duplex flange is 2205, due to its superior resistance to corrosion and mechanical strength. The designation “2205” is related to the chemical composition of this material, which features 22% of chromium and 5% of nickel. Super Duplex flange show an even superior strength and a higher corrosion resistance than standard duplex steel (and austenitic grades, of course). The main difference between a duplex and a super duplex grade is the addition of copper to the alloy (in addition to increased amounts of Chromium, Moly, and Nickel). The addition of copper gives Super Duplex Stainless Steel an improved resistance to hot chlorides and strong reducing acids, like sulphuric acid, compared to a standard Duplex grade. Whilst UNS S31803, UNS 32205 (duplex) and UNS S32750, UNS S32760 are standard designations, most manufacturers of superalloys attribute proprietary names to these steels (example UR52N+ is a Usinor/Arcelor Super Duplex steel, Ferralium, Zeron, Sandvik SAF 2205 22Cr, etc). NICKEL ALLOY FLANGES: Inconel® Flanges Inconel® is a family of austenite nickel-chromium-based superalloys. Inconel® alloys are oxidation and corrosion resistant materials well suited for service in extreme environments subjected to pressure and heat. When heated, Inconel® forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies. Inconel’s high temperature strength is developed by solid solution strengthening or precipitation strengthening, depending on the alloy. We offer flanges in the following grades: ALLOY 600 N06600 B366 (REF), B/SB 564, AMS 5665 B/SB 166 ALLOY 601 N06601 AMS 5715 B/SB 166 ALLOY 625 N06625 B366 (REF), B/SB 564, AMS 5666 B/SB 446 CANGZHOU WILSON PIPELINE manufacture of flange fittings&pipes Incoloy® Flanges Incoloy® refers to a range of superalloys produced by the Special Metals Corporation group of companies. They are mostly nickel-based, and designed for excellent corrosion resistance as well as strength at high temperatures; there are specific alloys for resistance to particular chemical attacks (e.g. alloy 020 is designed to be resistant to sulphuric acid, DS to be used in heat-treating furnaces with reactive atmospheres and many heat cycles) We offer flanges in the following grades: ALLOY 800 N08800 B 366 (REF), B/SB 564, AMS 5766 B/SB 408 ALLOY 800H N08810 B 366 (REF), B/SB 564 B/SB 408 ALLOY 800HT N08811 B 366 (REF), B/SB 564 B/SB 408 ALLOY 825 N08825 B 366 (REF), B/SB 564 B/SB 425 ALLOY C20 (F20) N08020 A 182, B 366, B/SB 462, B/SB 564 B/SB 472, B/SB 473 ALLOY 330 N08330 B 366 (REF), AMS 5716 B/SB 511, B/SB 512 Monel® and Copper Nickel Alloy Flanges Monel is a group of nickel alloys, primarily composed of nickel (up to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. Stronger than pure nickel, Monel alloys are resistant to corrosion by many agents, including rapidly flowing seawater. They can be fabricated readily by hot- and cold-working, machining, and welding. Monel alloy 400 is a binary alloy of the same proportions of nickel and copper as is found naturally in the nickel ore and is therefore considered a puritan alloy. It is a very expensive alloy, with cost ranging from 5 to 10 times the cost of copper and nickel, hence its use is limited to those applications where it cannot be replaced with cheaper alternatives. Compared to carbon steel, piping in monel is more than 3 times as expensive. CANGZHOU WILSON PIPELINE manufacture of flange fittings&pipes We offer flanges in the following grades: ALLOY 400 N04400 B366, B/SB 564, QQ-N-281, MIL-F-23509 B/SB 164 70/30 CUNI C71500 MIL-C-15726, MIL-C-24679 B/SB 151 90/10 CU-NI C70600 MIL-C-15726, MIL-C-24679 B/SB 151 Hastelloy® Flanges The Corrosion-Resistant HASTELLOY® alloys are widely used by the chemical processing industries. The need for reliable performance leads to their acceptance and growth in the areas of energy, health and environmental, oil and gas, pharmaceutical and flue gas desulfurization industries. The attributes of HASTELLOY® alloys include high resistance to uniform attack, outstanding localized corrosion resistance, excellent stress corrosion cracking resistance, and ease of welding and fabrication. B-3® alloy possesses outstanding resistance to non-oxidizing acids, such as hydrochloric acid and sulfuric acid. The advantages of B-3® alloy over previous B-family alloys are enhanced thermal stability and improved fabrication characteristics. The most versatile of the HASTELLOY® alloys are the “C-type” alloys. C-2000® alloy combines outstanding resistance to oxidizing media with superior resistance to non-oxidizing environments and represents a true performance breakthrough for chemical process equipment applications. C-22® alloy is particularly resistant to pitting and crevice corrosion; it has been used extensively to protect against the most corrosive FGD systems and the most sophisticated pharmaceutical reaction vessels. G-30® alloy has been very successful as phosphoric acid heat exchanger tubing and for other process components in the fertilizer industry. G-35® alloy was designed as an improved version of G-30 alloy in these applications. The high chromium content of both of these alloys make them the premier choices for strong oxidizing solutions and mixed acid pickling services.

DUPLEX & SUPER DUPLEX FLANGES: Duplex steel (ASTM A182 2205) is an extremely corrosion resistant, work hardenable stainless steel, whose microstructure consists of a mixture of austenite and ferrite phases. The most widely used grade for Duplex flange is 2205, due to its superior resistance to corrosion and mechanical strength. The designation “2205” is related to the chemical composition of this material, which features 22% of chromium and 5% of nickel. Super Duplex flange show an even superior strength and a higher corrosion resistance than standard duplex steel (and austenitic grades, of course). The main difference between a duplex and a super duplex grade is the addition of copper to the alloy (in addition to increased amounts of Chromium, Moly, and Nickel). The addition of copper gives Super Duplex Stainless Steel an improved resistance to hot chlorides and strong reducing acids, like sulphuric acid, compared to a standard Duplex grade. Whilst UNS S31803, UNS 32205 (duplex) and UNS S32750, UNS S32760 are standard designations, most manufacturers of superalloys attribute proprietary names to these steels (example UR52N+ is a Usinor/Arcelor Super Duplex steel, Ferralium, Zeron, Sandvik SAF 2205 22Cr, etc). NICKEL ALLOY FLANGES: Inconel® Flanges Inconel® is a family of austenite nickel-chromium-based superalloys. Inconel® alloys are oxidation and corrosion resistant materials well suited for service in extreme environments subjected to pressure and heat. When heated, Inconel® forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies. Inconel’s high temperature strength is developed by solid solution strengthening or precipitation strengthening, depending on the alloy. We offer flanges in the following grades: ALLOY 600 N06600 B366 (REF), B/SB 564, AMS 5665 B/SB 166 ALLOY 601 N06601 AMS 5715 B/SB 166 ALLOY 625 N06625 B366 (REF), B/SB 564, AMS 5666 B/SB 446 Incoloy® Flanges Incoloy® refers to a range of superalloys produced by the Special Metals Corporation group of companies. They are mostly nickel-based, and designed for excellent corrosion resistance as well as strength at high temperatures; there are specific alloys for resistance to particular chemical attacks (e.g. alloy 020 is designed to be resistant to sulphuric acid, DS to be used in heat-treating furnaces with reactive atmospheres and many heat cycles) We offer flanges in the following grades: ALLOY 800 N08800 B 366 (REF), B/SB 564, AMS 5766 B/SB 408 ALLOY 800H N08810 B 366 (REF), B/SB 564 B/SB 408 ALLOY 800HT N08811 B 366 (REF), B/SB 564 B/SB 408 ALLOY 825 N08825 B 366 (REF), B/SB 564 B/SB 425 ALLOY C20 (F20) N08020 A 182, B 366, B/SB 462, B/SB 564 B/SB 472, B/SB 473 ALLOY 330 N08330 B 366 (REF), AMS 5716 B/SB 511, B/SB 512 Monel® and Copper Nickel Alloy Flanges Monel is a group of nickel alloys, primarily composed of nickel (up to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. Stronger than pure nickel, Monel alloys are resistant to corrosion by many agents, including rapidly flowing seawater. They can be fabricated readily by hot- and cold-working, machining, and welding. Monel alloy 400 is a binary alloy of the same proportions of nickel and copper as is found naturally in the nickel ore and is therefore considered a puritan alloy. It is a very expensive alloy, with cost ranging from 5 to 10 times the cost of copper and nickel, hence its use is limited to those applications where it cannot be replaced with cheaper alternatives. Compared to carbon steel, piping in monel is more than 3 times as expensive. We offer flanges in the following grades: ALLOY 400 N04400 B366, B/SB 564, QQ-N-281, MIL-F-23509 B/SB 164 70/30 CUNI C71500 MIL-C-15726, MIL-C-24679 B/SB 151 90/10 CU-NI C70600 MIL-C-15726, MIL-C-24679 B/SB 151 Hastelloy® Flanges The Corrosion-Resistant HASTELLOY® alloys are widely used by the chemical processing industries. The need for reliable performance leads to their acceptance and growth in the areas of energy, health and environmental, oil and gas, pharmaceutical and flue gas desulfurization industries. The attributes of HASTELLOY® alloys include high resistance to uniform attack, outstanding localized corrosion resistance, excellent stress corrosion cracking resistance, and ease of welding and fabrication. B-3® alloy possesses outstanding resistance to non-oxidizing acids, such as hydrochloric acid and sulfuric acid. The advantages of B-3® alloy over previous B-family alloys are enhanced thermal stability and improved fabrication characteristics. The most versatile of the HASTELLOY® alloys are the “C-type” alloys. C-2000® alloy combines outstanding resistance to oxidizing media with superior resistance to non-oxidizing environments and represents a true performance breakthrough for chemical process equipment applications. C-22® alloy is particularly resistant to pitting and crevice corrosion; it has been used extensively to protect against the most corrosive FGD systems and the most sophisticated pharmaceutical reaction vessels. G-30® alloy has been very successful as phosphoric acid heat exchanger tubing and for other process components in the fertilizer industry. G-35® alloy was designed as an improved version of G-30 alloy in these applications. The high chromium content of both of these alloys make them the premier choices for strong oxidizing solutions and mixed acid pickling services.
