Stainless steel from the invention to the actual industrial application of time span of about ten years: 1904-1906 French Guillet first of Fe-Cr-Ni alloy metallurgy and mechanical properties of the groundbreaking basic research; 1907-1911, the French Portevin And British Gissen found the Fe-Cr and Fe-Cr-Ni alloy corrosion resistance and completed the Guillet research work; 1908-1911 German Monnartz reveals the corrosion resistance of steel and put forward the concept of passivation , Such as the critical chromium content, the role of carbon and molybdenum effects. Soon, the practical value of stainless steel in Europe and the United States was recognized, industrial stainless steel grades have also come out: 1912 ~ 1914, Brearley invented 12-13% Cr of martensitic stainless steel and patent; 1911-1914, the Americans Dant-sizen invented ferritic stainless steels containing 14-16% Cr, 0.07-0.15% C; German Maurer and Strauss invented austenitic stainless steels containing 1.0% C, 15-20% Cr, <20% Ni , Then, on the basis of the development of the famous 18-8 stainless steel (0.1% C-18% Cr-8% Ni). In practice, high-carbon austenitic stainless steels were found to be very serious intergranular corrosion problems, after Bain proposed the theory of intergranular corrosion of chromium-poor, and in the early 30s on the basis of 18-8 stainless steel developed titanium, Niobium stabilized austenitic stainless steel, namely AISl321 and AISl347. The same period also invented the ferrite – austenite duplex stainless steel, and put forward the ultra-low carbon (C ≤ 0.03%) the concept of stainless steel, but limited to the metallurgical equipment and technology level can not be used in industry. As early as 1934, American Folog invented the precipitation hardening stainless steel, in the 40 ~ 50’s martensite, semi-austenitic precipitation hardening stainless steel began for military and civilian industries. This series is based on the United States Steel (U.S.Steel) successfully produced StainlessW as a starting point. In addition, in order to save nickel element invented the nickel-manganese to Cr-Ni-Mn-N series stainless steel, the United States AISl200 series steel. After World War II, due to the development of the fertilizer industry and nuclear fuel industry, greatly stimulated the development of stainless steel, and because of the emergence of oxygen steel, 1947 ultra-low carbon type of stainless steel began commercialization. In the mid-1950s, high-performance stainless steel with excellent corrosion resistance was developed. In the late 1960s, high purity ferritic stainless steels with martensitic aged stainless steel, TRIP (Transformation Induced Plasticity) stainless steel and C + N ≤ 150 ppm were successively developed. In recent 20 years, by various local corrosion damage accidents, and the chemical processing industry continue to adopt new catalysts and new technology, has been developed on the basis of resistance to stress corrosion, pitting corrosion resistance, crevice corrosion, corrosion fatigue Special stainless steel, such as duplex stainless steel, high molybdenum stainless steel, high silicon stainless steel. In order to meet the needs of deep drawing and cold pier forming also developed a special type of stainless steel easy to shape. At present, the stainless steel series is also constantly improving. Since the late 20th century, since the late 1960s, a variety of production of stainless steel refining equipment and continuous casting equipment production, the world has also been completed with titanium stabilized austenitic stainless steel to low carbon, ultra-low carbon austenitic stainless steel transition, Stainless steel production level has reached a new level. The History of Chinese Stainless Steel China’s stainless steel industry developed late in 1952, industrial production began. Since 1949, after the mass production of stainless steel with electric arc furnace, after the first production Cr13 type martensitic stainless steel, master production technology, and then mass production of 18-8 Cr-Ni austenitic steel, such as 1Cr18Ni9Ti, began in 1952. Followed by the development of the domestic chemical industry, and began to produce with Mo2% -3% 1Cr18Ni12Mo2Ti and 1Cr18Ni12Mo3Ti and so on. At the same time in order to save valuable elements of nickel, since 1959 to imitate Mn, N on behalf of the Ni 1Cr17Mn6Ni5N and 1Cr18Mn8Ni5N, 1958 to AISI204 steel by Mo2% -3%, developed 1Cr18Mn10Ni5Mo3N (204 + Mo), for the whole Cycle urea production plant to replace 1Cr18Ni12Mo2Ti. From the late 1950s to the early 1960s, industrial trial production of 1Cr17Ti, 1Cr17Mo2Ti and 1Cr25Mo3Ti and other non-nickel ferrite stainless steel and began to study the fuming nitric acid corrosion of high silicon stainless steel 1Cr17Ni14Si4ALTi (equivalent to the Soviet Union grade ЭИ654), this steel actually Is an α + γ duplex stainless steel. 60 years, due to the domestic chemical industry, aerospace, aviation, atomic energy and other industrial development needs and the use of electric furnace oxygen steelmaking technology, a large number of new steel, such as 17-4PH, 17-7PH, PH15-7Mo precipitation hardening stainless steel, C ≤ 0.03% of ultra-low carbon stainless steel 00Cr18Ni10, 00Cr18Ni14Mo2, 00Cr18Ni14Mo3 and Ni-free Cr-Mn-N stainless steel 1Cr18Mn14Mo2N (A4) have been successfully developed and put into production. Since the 1970s, in order to solve the chloride and stress corrosion problems of 18-8 Cr-Ni steel in the chemical and atomic energy industries, some α + γCr-Ni duplex stainless steel have been developed and put into production and application. The main steel grades There are 1Cr21Ni5Ti, 00Cr26Ni6Ti, 00Cr26Ni7Mo2Ti, 00Cr18Ni5Mo3Si2 (3RE60) and 00Cr18Ni6Mo3Si2Nb and so on. 00Cr18Ni6Mo3Si2Nb is to solve the Swedish brand 3RE60 prone to single-phase ferrite welding after welding, resulting in decreased corrosion resistance and toughness and the development of N, Nb α + γ duplex stainless steel. Into the eighties, the development and imitation of the N containing the second generation of α + γ duplex stainless steel to address chloride pitting corrosion, crevice corrosion and other local corrosion damage, such as 00Cr22Ni5Mo2N, 00Cr25Ni6Mo3N and 00Cr25Ni7Mo3WCuN, etc., not only China’s duplex Stainless steel system, but also deeply studied its structure and performance and N in duplex stainless steel in the mechanism of action. Since the seventies, China’s stainless steel research work in other important progress: the development of high strength and ultra-high strength martensitic aging stainless steel and put into industrial trial and application; the use of vacuum induction furnace, vacuum electron beam furnace and vacuum consumption Furnace smelting and mass production of C + N ≤ 150-250ppm of high purity ferritic stainless steel 00Cr18Mo2, 00Cr26Mo1 and 00Cr30Mo2; Mo content of ≥ 4.5% of high Mo and high MoN-containing Cr-Ni austenitic stainless steel, such as the successful development 00Cr25Ni18Mo5 (N), 00Cr25Ni25Mo5N and so on in the chemical, petrochemical and marine development areas such as access to applications in the solution of concentrated nitric acid corrosion and solid solution intergranular corrosion, the development of 00Cr25Ni20Nb and several ultra-low carbon high Silicon stainless steel. Since the eighties, ultra-low carbon steel and phosphorus content and α-phase amount of strict control of urea-grade stainless steel 00Cr18Ni14Mo2 and 00Cr25Ni22Mo2N two grades developed, their plates, tubes, bars, forgings and welding materials are used in the Large and medium-sized urea industry, and the results are satisfactory; as a result of some special steel smelting stainless steel have been built outside the furnace refining equipment, such as AOD (argon oxygen refining furnace), VOD (vacuum oxygen refining furnace) and has been put into operation, making China Stainless steel smelting technology to a new level. It not only makes the production of low-carbon, ultra-low carbon stainless steel easy, but also to achieve a significant cost reduction of stainless steel efficiency. As a result of Ti 18-8 Cr-Ni austenitic steel there are a series of shortcomings, the United States, Japan and other advanced industrial countries as early as 60 years has been achieved by the Ti-containing stainless steel to the widespread use of low-carbon, ultra-low carbon stainless steel Transition, and China is in 1985-1990 years to vigorously low carbon, ultra-low carbon stainless steel development, production and application of progress gratifying, such as the end of 1988 China’s low carbon, ultra-low carbon 18-8 stainless steel production accounts for China’s stainless steel Production of about 10%. However, compared with the advanced countries of stainless steel production and application (such as Japan, the United States and other countries with Ti 18-8 Cr-Ni steel production accounts for only about 1.5% of stainless steel), the gap is still large. In the 1980s, China developed nitrogen-controlled (N 0.05-0.10%) and nitrogen-alloyed (N> 0.10%) Cr-Ni austenitic stainless steels. The results show that N is a beneficial element in Cr-Ni austenitic stainless steels and duplex stainless steels. N element can enhance the sensitivity of intergranular corrosion of stainless steel to improve the corrosion resistance of stainless steel, in particular, to improve the corrosion resistance of stainless steel and other aspects of the mechanism.

Butt welding elbow is a kind of using steel by hot pressing molding technology or forging forming technology of production of the elbow, the connection method is through the elbow with the steel pipe butt welding, using resistance heat two artifacts along the entire face welded together at the same time, the two methods usually have butt welding and flash butt welding, high productivity, easy automation, so has won a wide range of applications. Butt welding elbow electrode should be kept dry, when using titanium calcium type should be 1 hour after 150 ℃ drying, low hydrogen type should be 1 hour after the 200-250 ℃ drying (can’t repeat drying, otherwise the skin easy cracking flake), prevent electrode surface sticky oil and other dirt, lest cause weld increased carbon content and affects the quality of weldment. When the welding elbow, carbide precipitation by repeated heating, reduce corrosion resistance and mechanical properties. Butt welding elbow during the welding process needs to be in accordance with the instructions and the form of actual control, make its elbow products can fully show the use of good characteristics and performance, ensure the quality of the good contribution and. The butt welding elbow generally have a 45 degree Angle, 90 degree Angle, 180 – degree Angle and so on, the material is carbon steel, alloy steel and stainless steel. According to its radius of curvature to points, can be pided into long radius elbow and short radius elbow. Long radius of bend radius of curvature is equal to 1. 5 times the pipe diameter, that is, R = 1. 5 d. Bend radius of curvature is equal to the pipe diameter, short radius R = 1 d. Type D bend diameter of R for the radius of curvature. If no specific instructions, general selection is 1.5 D bend. Sclerosing after welding is bigger, easy to crack. If using the same type of electrode welding, must be above 300 ℃ preheat and 700 ℃ or so slow cooling after welding. If cannot undertake the weldment heat treatment after welding, it should choose chromium nickel stainless steel electrode. To improve the gb elbow corrosion resistance and weldability and appropriately increased moderate stability element Ti, Nb and Mo, weldability is better, using the same type of chromium stainless steel electrode, should be above 200 ℃ preheat and around 800 ℃ tempering treatment after welding. If cannot undertake the weldment heat treatment, should choose chromium nickel stainless steel electrode. In gb elbow welding need to follow certain standards and forms, need according to the use of good form and process for making and welding, can fully show the value of a good contribution.

The design and manufacture of carbon steel elbow must be considered when the hardness of the carbon steel elbow, so how to improve the hardness of the carbon steel elbow? Through research we found that the carbon steel elbow need heat treatment process: carbon steel elbow heated to a certain temperature and heat preservation for a period of time, and then make it slowly cooling, called annealing. Hot bend annealing is a heat the steel to the phase change or part of the phase transition temperature, slow cooling after heat preservation heat treatment method. The purpose of annealing is to eliminate tissue defects, improve the organization make composition uniformity and fine grains, increase mechanical properties of the hot pressing elbow, reduce the residual stress. Carbon steel elbow is widely used in petroleum, natural gas, chemical industry, water and electricity, construction and boiler pipe butt welding elbow is forming process is complicated, need according to the use of the different material and welding, gradually forming under the certain pressure. The advantages of carbon steel elbow molding process: 1, don’t need tube billet as raw material, can cut down the cost of pipe equipment and mould, and can get any big diameter and wall thickness is relatively thin, the size of the head. The size of the head material is special, don’t need to join the pipe material, easy to control during machining. 2, does not need tube billet as raw material, can cut down the cost of pipe equipment and mould, and can get any big diameter and wall thickness is relatively thin carbon steel elbow. 3, due to the above two reasons, can shorten the manufacturing cycle, the production cost greatly reduced. Because do not need any special equipment, especially suitable for machining of carbon steel in site the size of the head. Carbon steel elbow welding first a cross section of a polygon or both ends closed multi multi ring shell fan shell, internal filled with medium pressure, with inner pressure and internal pressure under the action of cross section of polygonal gradually became round, and eventually become a circular ring shell. According to the need of a circular ring shell can be cut into four 90 degree bend or six 60 degree elbow or other specifications of the elbow, the process is suitable for manufacturing elbow pitch diameter and any specifications of large elbow bend diameter ratio greater than 1.5, is the ideal way to make the large carbon steel elbow.

Bend and elbow the biggest difference is that one is the head, one is the tube. Although this is so, but they are two in the manufacturing process there is a big difference. The most essential difference is that bend is slightly longer than elbow, R=1-2 times is the elbow, and then the big is bend. Manufacturing process on the cold bend will be relative to some simple, you can use the ready-made straight pipe bending, one step can be completed, it does not require the two anti-corrosion. But elbow production is required in accordance with the size of the custom, but also need to do anti-corrosion, long delivery period is relatively long. In the price, bend than elbow to high, then the price will be greater than the bend. But because of the price advantage, bend in the use of the process, compared to some of the more. National west east gas transmission project is the use of 1016*17.5 pipe, elbow used in the position of greater than eleven degrees, less than eleven degrees angle with the bend. Of course, the cost of bend is low. If the cost is to consider a simple elbow, hot bending, cold bend can, so the cost is high elbow. However, be sure to use the elbow in a narrow area in the trench stonework section, the elbow curvature radius is small, mostly 6D, but bend 40D. Elbow is the most notable feature is clean and sanitary, high temperature resistance, anti ultraviolet performance is strong, is a kind of new material with high added value. In which the inner wall of the stamping elbow pipe is smooth, the heat flux is small, and the resistance to acid and alkali, so the service life is long, and it is easy to install. The thermal conductivity of elbow is applied to the floor heating. This kind of pipe is generally required for thermal conductivity and low temperature impact resistance. So that the pipe is not easy to meet the impact of low temperature caused by the rupture of the pipe, but also do not pollute the environment, can be recycled. If you can not be recycled will produce two pollution of the environment. Stamping elbow has a very good long-term pressure performance, only in this regard, the strongest elbow. However, in the influence of various factors, the wall of the pipe floor heating tube is generally two mm thick. This wall thickness requires all pipes to be able to meet, which is difficult to reflect the advantages of bend. Now the general characteristics of the pipe is: carry a strong impact on the performance of strong, smooth surface, long life: in the high temperature or low temperature can have a more prominent softness; Now, the application of bend and elbow is very extensive, so we need to continue to make technology innovation and continuous improvement to meet the needs of consumers.

2205 duplex stainless steel elbow has excellent intergranular corrosion resistance and uniform corrosion resistance, both of which are better than 304L steel and 316L steel. The welding performance is good, the tendency of hot cracking is low, the brittleness tendency is small, can be cold, hot processing and forming. However, deep drawing, deep drawing, spinning and other cold forming is more difficult than austenitic stainless steel. Generally cold deformation of 10%, need to do solid solution annealing treatment. Cold bending deformation of more than 20% or the use of conditions to produce stress corrosion of the workpiece should be done with solid solution annealing treatment. Hot forming such as hot bending should be heated at 950 to 1150 degrees. Solid solution annealing treatment should be done after hot forming. Oil and gas production in acid with 2205 duplex stainless steel and stainless steel elbow, oil refining, pulp, chemical fertilizer, petrochemical and other fields, with the hand manufacturing heat exchanger, and condenser should be easy to produce pitting and stress corrosion of pressure equipment, can replace 304L and 316L austenitic stainless steel elbow. 2205 duplex stainless steel is used for oil and gas pipeline in Sweden, first developed SAF2205 steel. 00Cr22Ni5Mo3N steel was developed in China in 1980s. The American brand is UNS 31803 SAF2205. German brand is: W-Nr, 1.4462, DINX2CrNiMoN2253, France is 2205-03 Z2CND, Sweden is SS2377.

Stainless steel is one of the most important inventions in the 20th century, during the past hundred years of development and research has formed a series of more than 300 brand of steel grade. Visible, as an important material of stainless steel becomes more and more important for people, it is installed in engineering materials plays a role can not be ignored. Stainless steel elbow, of course, as a kind of pipe installation accessories products, plays an important role. As we all know, stainless steel elbow is different from carbon steel elbow is the main material of different. The chemical composition of the stainless steel elbow will keep the bend surface for a long time without rust. Then what metal elements can make the stainless steel elbow so good with carbon steel elbow it? We all know that the industrial grade stainless steel elbow is austenitic stainless steel. Austenitic stainless steel is greater than 18%, and chromium containing 8% nickel, of course, which also contains a small amount of copper, titanium, nitrogen and other elements. This kind of steel contains a large amount of nickel and chromium to make steel at room temperature in a state of austenite. Visible, chromium and nickel in stainless steel play an important role. Now we talk about the role of chromium in the stainless steel elbow: stainless steel elements is decided only one is Cr, so far, no chromium stainless steel, add chromium in stainless steel, the contradiction of internal corrosion resistance, resistance to damage the direction of development. The addition of chromium content in the steel reached more than 10 in order to form chromium passivation protective membrane stability, protection of steel against atmospheric corrosion, corrosion resistance of stainless steel increased with increasing chromium content. Then we talk about the role of nickel in stainless steel elbow: nickel is an excellent corrosion resistant material, which is an important alloying element in alloy steel. Nickel in stainless steel to join, the crystal structure changes from cubic face centered cubic structure, the steel is easy to form a single organization (austenite) steel, has not formed the micro battery capacity, so as to avoid being the main reasons for the corrosion of steel. In stainless steel, if the nickel can reach 24%, the microstructure of pure austenite can be obtained, and the corrosion resistance of the steel in some medium can be significantly changed by 27%. However, nickel and chromium exist in stainless steel, nickel can play a lot of valuable role in stainless steel. Source: wilsonpipeline Pipe Industry Co., Limited (www.wilsonpipeline.com)
