SPECIFICATIONS: GRADE Lean Duplex | UNS S32304 | ASTM/ASME A240 | Werkstoff 1.4362 Lean duplex 2304 is a 23‰ Cr, 4‰ Nickel, Mo free duplex stainless steel (23.04). We hold stock of duplex alloys in plate, sheet, and bar from our warehouse in the CN. We often meet specialist alloy profiling requirements and are a global supplier. The alloy lean duplex 2304 has similar corrosion resistance properties to 316L. Furthermore, its mechanical properties i.e. yield strength, are twice those of 304/316 austenitic grades. This allows the designer to save weight, particularly for properly designed pressure vessel applications. The alloy is particularly suitable for applications covering the -50°C/+300°C (-58°F/572°F) temperature range. Lower temperatures may also be considered, but need some restrictions, particularly for welded structures. With its duplex microstructure, low nickel and high chromium contents, the alloy has improved stress corrosion resistance properties compared to 304 and 316 austenitic grades.

Stainless-steel appliances look amazing, but grease and fingerprints can make a fancy fridge look dingy. Weblog The Kitchn shows you how to get a streak-free shine with vinegar and olive oil. All you need is a spray bottle, a soft cloth (microfiber is better), apple cider vinegar, and essential olive oil: Obtain the direction from the grain. You’ll notice going horizontally or vertically. Spray the apple cider vinegar at first glance liberally. Then wipe it down using your cloth going the direction with the grain. Dip the soft cloth in to the extra virgin olive oil—not too much—and polish your appliance going toward the grain. In case you don’t have olive oil you need to use another sort of olive oil you’ve got in the kitchen area. You can also use dish soap to clean your stainless-steel if you like. Just be sure to wipe towards the grain! wilsonpipeline Pipe Industry Co., Limited Contact Person : Ms. Yane Job Title : sales manager Business Phone :+86-15557558661 Skype :skaifox Email :sales@wilsonpipeline.com Website: www.wilsonpipeline.com

Atmospheric corrosion: It can be used for its resistance to atmospheric corrosion where its th losses are much lower than those of weathering steels, and still ten time than for zinc or galvanised steel. It is also lower than for aluminium. However , after a few months of service, stainless steel 1.4003 may develop a brown oxide layer which may be objectionable when cosmetic corrosion is not acceptable. Transport systems: The surface of stainless steel 1.4003 allows a regular flow of materials such as coal, ores, fertilisers, wood chips, cement and other granular products. The sliding ability of stainless steel 1.4003 is maintained where structural steel surfaces lose their sliding properties because of oxidation and rust. Stainless steel 1.4003 therefore reduces clogging problems. Water: Stainless steel 1.4003 has a better cavitation resistance than low alloy steels and may be used to protect HSLA steels from wear and cavitation effects in hydraulic systems, such as bends or areas of turbulent flow. However stainless steel 1.4003 is a 12%Cr steel and may be subject to localised corrosion in water environments. Check with our specialists in case of doubt, as impurities such as chlorides, fouling, microbiological activity and temperature may require higher alloyed materials. Wet abrasion and abrasion corrosion: In wet abrasive conditions, stainless steel 1.4003 represents an alternative when carbon steels or even abrasion resistant steels suffer from corrosive attack or loss of sliding properties. Such applications have been found in ore mining, coal mining, oil sands exploitation, slurry pipes, ash disposal in power stations and in the sugar industry. Endless screws, conveyors, hoppers, chutes, bins, screens are examples of potential areas for combined abrasion and corrosion. High temperature and oxidation resistance: Stainless steel 1.4003 may be used in refinery equipments to resist moderate sulphur attack, in chimneys, stacks, hot exhaust gas ducts, etc. It withstands oxidation up to 600°C (1100°F) in air or clean combustion atmospheres. The maximum service temperature limit is lower when sulphur containing impurities or chlorides are present or in reducing atmospheres. Creep must be considered when temperature exceeds approx 450°C (800°F). Welding Stainless steel 1.4003 is readily weldable employing the same processes as stainless steel. The parts to be welded must be clean and free of foreign material or dirt. Although the composition of stainless steel 1.4003 has been balanced to limit grain growth in the heat affected zones, the heat input should be limited to 2kJ/mm and interpass temperature limited to 200°C (392°F). Stainless steel 1.4003 can be welded by SMAW, GTAW, GMAW, SAW, FCAW using filler materials type 309L, which are also used to weld stainless steel 1.4003 to carbon steel. As for all ferritic steels, a low hydrogen practice is recommended which includes careful drying of welding fluxes and coatings, avoiding condensation on parts to be welded and protection from wet atmospheres. No post weld heat treatment is normally required for stainless steel 1.4003. Preheating is not necessary except when welding parts at less than 5°C (40°F) where a soft preheating at 20-50°C (70°-120°F) is advisable. APPLICATIONS Agriculture and forming equipment Transport systems, ore or coal railway cars high flow surfaces in material handling systems Target plates in hydropower systems Sugar beet processing Exhaust gas ducts or chimneys Refinery equipment Cement storage bins Sewage plant equipment Oil sand slurry piping Welded structures

303 Stainless Steel wilsonpipeline Stainless inventory includes 303 grade stainless steel (UNS S30300) in Flanges, Pipe Fittings, Pipe. General Properties Alloy 303 is a non-magnetic, austenitic stainless steel that is not hardenable by heat treatment. It is the free machining modification of the basic 18% chromium / 8% nickel stainless steel. Alloy 303 was specially designed to exhibit improved machinability while maintaining good mechanical and corrosion resistant properties Due to the presence of sulfur in the steel composition, Alloy 303 is the most readily machineable austenitic stainless steel; however, the sulfur addition does lower Alloy 303’s corrosion resistance to below that of Alloy 304. Like other austenitic grades, Alloy 303 demonstrates excellent toughness, although the sulfur does reduce this a little as well. Applications Alloy 303 is frequently used in applications that require parts to be heavily machined. Some examples include: Nuts and bolts Aircraft fittings Gears Screws Shafts Electrical switchgear components Bushings Standards – Alloy 303 ASTM/ASME ……………. UNS S30300 EURONORM ……………. FeMi35Cr20Cu4Mo2 DIN …………………………  2.4660 Corrosion Resistance Good resistance to mildly corrosive atmospheres, but significantly less than Alloy 304 When additional sulfur is added to improve machinability, it can often slightly reduce corrosion resistance In most dry and mild corrosive environments, Alloy 303 is comparable to other unmodified alloys Should not be exposed to moist, marine environments as it is subject to rapid-pitting corrosion and a rust film will tend to form Like other common austenitic stainless steels, it is subject to corrosion cracking in chloride environments above 60oC Heat Resistance Good oxidation resistance at temperatures up to 1700oF (927 oC) Continuous use at temperatures above 1400oF (760oC) is not usually recommended due to carbide precipitation which can lead to irregular scaling Does not have a low carbon content so it is also vulnerable to sensitisation Welding Characteristics Not generally recommended, but may be welded with some difficulty May be welded with Alloy 310 electrodes Should be annealed after welding to re-dissolve precipitated carbides Machinability High machining rates can be obtained in the annealed condition with hardness in the range of 200 to 240 Brinell Will work harden, therefore, it should be machined at reduced surface feet per minute and heavier feeds to prevent glazing at the tool interface.
