Stainless steel is usually divided into stainless steel pipe, stainless steel pipe and ferritic stainless steel according to the matrix structure. Chromium content % ~ %. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its chloride stress corrosion resistance is better than other kinds of stainless steel.For more than years, such as the Chrysler Building in New York City. However, in many other applications, the role of stainless steel is not so eye-catching, but in the aesthetics and performance of buildings For example,Palma-SorianoHigh hardness stainless steel strip, because stainless steel has more wear resistance and pressure resistance than other metal materials of the same thickness, it is the preferred material for designers when building sidewalks in places with large population flow.Palma-Soriano,: stainless steel strip (stainless steel coil): or coil, coil, coil, plate coil. There are many names, and the hardness of the strip varies from dozens to hundreds. The customer needs to determine which hardness to use first. (K mirror luminosity)There are mechanical, chemical and electrochemical methods to remove the scale of stainless steel pipe. Due to the complexity of the composition of the scale of stainless steel pipe, it is not easy to remove the scale on the surface and make the surface highly clear and flat. Generally, the first step is pretreatment and the second step is ash removal.Genet,Model & mdash; The corrosion resistance is the same, and the strength is better because the carbon content is relatively high.When the stainless steel pipe with solid core welding wire is prefabricated, the welded junction can usually be rotated for welding, and the ventilation is very easy. At this time, the blocking plate is usually used to block both sides of the welded junction in the pipe, and the bottom welding is carried out for the protection of ventilation (see Table ), and the outside is blocked with adhesive cloth.When improved, it is possible to use it in refrigeration related engineering. Recently,Palma-Soriano4-point stainless steel pipe, suslx (cr Ti, Nb LC) and susl have been applied to frozen shells. Ferritic stainless steel has body centered cubic structure. When the material properties become weaker, sharp cracks will expand rapidly and cause brittleness. Austenitic series stainless steel will not produce brittleness because it has face centered cubic structure. Austrian stainless steel SUSL (cr-ni LC) and SUSL (cr-ni-mo-lc) shows that it still has superior impact characteristics at low temperature. However, pay attention to the precipitation of ferrite or martensite due to processing, and the tendency of embrittlement due to sensitized carbide or & sigma; equal heterogeneous precipitation.

Since the beginning of last year foreign countries have frequently carried out & ldquo; Double inverse & rdquo; This has a great impact on China's stainless steel casting industry. Export is a large part of the development of China's stainless steel industry and occupies a huge market share in its industrial development. In the face of economic downturn and slow development, the development of China's stainless steel industry should constantly improve product quality, Better develop overseas trade and deal with trade protectionism, combine products with environmental protection, energy resources and cultural environment, and improve the competitiveness of stainless steel products. Only in this way can we achieve an invincible position in foreign trade.Windproof and ventilation. Where there is wind, please take measures to block the net and take appropriate ventilation measures indoors.During welding, the process of ventilation in advance and gas stop behind shall be adopted, and the adhesive cloth on the outside shall be torn off while welding. Because the blocking plate is composed of rubber and white iron sheet, it is not easy to be damaged, so this welding can well ensure that the inner side of the weld is filled with argon and its purity, so as to effectively ensure that the metal on the inner side of the weld is not oxidized and ensure the quality of weld backing welding.Good quality, the storage position shall be convenient for lifting and absolutely isolated from other data storage areas. Protective measures shall be taken to avoid purification, collision with other components, purification and damage of iron metal.Stainless steel pipes can be divided into CR series ( Series), Cr Ni series ( Series), Cr Mn Ni series ( Series) and precipitation hardening series ( Series). Series & mdash; Cr Ni Mn austenitic stainless steel series & mdash; Cr Ni austenitic stainless steel.There is a bright future for domestic substitution for imported stainless steel pipes. Since the s, China has solved the problem of reducing wall thickness and cost; High diameter to wall ratio and high precision & rdquo; The technical problems of stainless steel pipe make the stainless steel pipe applied and developed rapidly. If a pipeline can be fully applied, localization is indispensable. At present, some domestic have the ability to produce and further develop stainless steel pipes and fittings.

Pipeline direct drinking water has developed rapidly. With the development of national economy, pipeline direct drinking water has developed rapidly in domestic cities such as Beijing, Shenzhen, Shanghai and Chongqing, and economically developed medium-sized cities have also actively planned to catch up. In direct drinking water, stainless steel pipe system is undoubtedly second to none. At present, domestic high-grade hotels and public places have been equipped or are equipped with direct drinking water pipes.Honesty and mutual benefit,After that, the second widely used steel is mainly used in food industry, pharmaceutical industry and surgical equipment. Adding molybdenum makes it obtain a special corrosion-resistant structure. Because it has better chloride corrosion resistance than stainless steel pipe it is also used as & ldquo; marine steel & rdquo;. SS is usually used in nuclear fuel recovery devices. Grade stainless steel Steel pipes usually also meet this application level.As we all know, stainless steel pipe has a strong ability of atmospheric oxidation and is not easy to rust under normal circumstances, & ldquo; Stainless steel pipe & rdquo; Hence the name of. But what I want to tell you today is that stainless steel pipes will also rust. I believe many friends will be surprised! I believe there are many people who don't know how to explain to customers! Next, stepped pipes and periodic section pipes.Palma-Soriano,The scale pretreatment of stainless steel pipe makes the scale loose, and then acid pickling is carried out for easy removal. The pretreatment can be divided into the following: alkaline salt melting treatment method. The alkaline melt contains % hydroxide and % salt. The proportion of the two in the molten salt shall be strict, so that the molten salt has strong oxidizing power, low melting point and small viscosity. Only the sodium halo shall be analyzed in the production process, and the content shall not be less than % (wt) It is treated in a salt bath furnace at ~ ℃ for minutes for ferritic stainless steel and minutes for austenitic stainless steel. Similarly, iron oxides and spinels can also be oxidized by salt to become loose ferric oxide, which is easy to be removed during acid pickling. Due to the action of high temperature, some of the formed oxides peel off and sink to the furnace bottom in the form of sediment. Alkaline salt melting pretreatment Process flow: steam degreasing → preheating ( ~ ℃, time ~ min) ↠ molten salt treatment & rarr; water quenching & rarr; hot water washing. Molten salt treatment is not suitable for assemblies with weld gap or crimping. When the parts are taken out of the molten salt furnace, a stream of alkali and salt mist will be splashed during water quenching, so deep well anti splash water quenching tank shall be used during water quenching. During water quenching,Palma-SorianoN08367 stainless steel plate, firstly lift the parts basket into the tank, stop above the horizontal plane close the tank cover, and then lower the parts basket into the water, Professional L stainless steel pipe, s stainless steel pipe and L stainless steel pipe are stable, safe, reliable and maintenance free. The technical level has reached the domestic level and the international advanced level of similar products until submerged.During welding, and the adhesive cloth on the outside shall be torn off while welding. Because the blocking plate is composed of rubber and white iron sheet, it is not easy to be damaged, so this welding can well ensure that the inner side of the weld is filled with argon and its purity, so as to effectively ensure that the metal on the inner side of the weld is not oxidized and ensure the quality of weld backing welding.. Raw material problem of stainless steel pipe. If the hardness is too low, it is not easy to polish (BQ is not good). If the hardness is too low, orange peel is easy to appear on the surface during deep drawing which affects BQ performance. BQ with high hardness is relatively good.
