SS 32750 And SS 32760 Steel Strip Coil

S32750 stainless steel is a ferritic-austenitic (duplex) stainless steel. It combines many beneficial properties of ferritic steel and austenitic steel. Since the content of chromium and molybdenum in this steel is high, it has very high Good resistance to pitting corrosion, crevice corrosion and uniform corrosion. The dual-phase microstructure ensures that the steel has high resistance to stress corrosion cracking and high mechanical strength. 1. Corresponding grades of F53 stainless steel: 1.
