Description of Super Duplex Stainless Steel 2507--The 24th China(Guangzhou)Int'l Stainless Steel Industry Exhibition
9/18/2023 不锈钢展-Stainless Steel exhibition |

Super duplex 2507 steel contains 25% chromium, 4% molybdenum and 7% nickel. It is of strong intensity and corrosion resistance, and is mainly used in chemical processing, petrochemical and subsea equipment. Besides, this stainless steel is also resistant to chloride corrosion, high thermal conductivity and low coefficient of thermal expansion. With high content chromium, molybdenum and nitrogen, it can resist spot corrosion, crack corrosion and general corrosion.
S322507 also has a very high impact strength. But it cannot be used under the temperature of 570 Degree. If putting it under this environment for a long period of time, its intensity will be decreased. This stainless steel integrated with many advantages of ferritic steel and austenitic steel. Due to high content of chromium and molybdenum, it has excellent resistance to corrosion, crevice corrosion and the ability of uniform corrosion. Duplex microstructure also guaranteed that it can resist to stress corrosion cracking, and the mechanical strength is high.
