At low temperature, the company specializes in selling stainless steel plates, coils, belts and tubes with quality assurance. The company specializes in selling, timely supply and high cost performance. It has become the first choice brand for many wire products. Welcome to buy! Ferritic stainless steel tubes have low temperature brittleness like carbon steel, while austenitic steel does not. Therefore,Products Show ferritic or martensitic stainless steel produces low temperature brittleness Temperature embrittlement,316 square tube priceNews resources but austenitic stainless steel or nickel base alloy does not show low temperature embrittlement. Sus (Cr), SUS of ferritic stainless steel pipe (cr) and others show a sharp drop in impact value at low temperature. Therefore it is necessary to pay special attention when using at low temperature. As a way to improve the impact toughness of ferritic series stainless steel, high purification process can be considered. With the help of grade C and N when the embrittlement temperature is improved in the range of - ℃ to - ℃, it is possible to use it in freezing related projects SUSL has applied suslx (cr Ti, Nb LC) and susl (cr Mo Ti, sharp cracks will expand rapidly and cause brittle failure. Austenitic series stainless steel will not produce brittle failure because it is face centered cubic structure. Arctech has invested in stainless steel (cr-ni-lc) and SUSL (cr-ni-mo-lc) show that they still have superior impact characteristics at low temperature. However, pay attention to the precipitation of ferrite or martensite due to processing, and the tendency of embrittlement caused by carbide or & sigma; equal heterogeneous precipitation due to sensitization.

9Its plastic toughness is lower than that of austenitic stainless steel, and its cold and hot working process and formability are not as good as that of austenitic stainless steel.

rAustenitic stainless steel has good resistance to uniform corrosion,Products Show but there are still the following problems in local corrosion resistance: intergranular corrosion of austenitic stainless steel. Austenitic stainless steel will have intergranular corrosion when it is kept warm at ~ ℃ or cooled slowly. The higher the carbon content, the greater the tendency of intergranular corrosion. In addition, intergranular corrosion also occurs in the heat affected zone of the weldment. This is due to the precipitation of Cr rich CrC on the grain boundary. The chromium poor area is formed in the surrounding matrix, which is caused by corrosion of the primary cell. This intergranular corrosion phenomenon also exists in the ferritic stainless steel mentioned above.

For example, if the actual thickness of stainless steel round pipe is ., the weight of a single -meter-long stainless steel pipe is (-... = kg, and the theoretical weight of a -meter-long round pipe is .. For example, the weight of a single -meter-long stainless steel pipe of stainless steel square pipe with a thickness of . is [( + --... = kg). If the weight of stainless steel pipe per meter is calculated, the length can be changed into one meter.

m. 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.

TStainless steel pipe will rust? It will rust. The stainless steel pipe only means that it is not easy to rust, which does not mean that it will not rust. If it is placed in seawater, it will still be embroidered soon. It will not rust at room temperature. If it is in a high sulfate alkali environment for a long time, it will produce spot rust. It will not rust under normal circumstances, except in places with acid rain. Stainless steel pipe itself will not rust, but improper use and maintenance will cause & ldquo; Floating rust& ldquo; Mildew & rdquo; And other undesirable phenomena.

OQuality departmentDo a good job of preliminary data research. In the highly competitive market, stainless steel pipe dealers should go deep into the hinterland. It is essential and crucial to do a good job of pre market data research; Only by fully grasping consumer demand trends, habits and other data can we have more confidence to compete for market share. Therefore, the editor of stainless steel pipe believes that in-depth data mining and comprehensive market analysis are powerful for stainless steel control manufacturers in this movement.

jSLow temperature embrittlement --- in low temperature environment, the deformation energy is small. In the low temperature environment, the phenomenon that the elongation and area shrinkage decrease is called low temperature embrittlement. Most of them are produced on the body centered cubic structure of ferrite series.
