S32750 （1.4410）

Summary

Stainless steel S32750(Alloy2507, F53, DIN 1.4410) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel. The high chromium, molybdenum and nitrogen levels provide excellent resistance to pitting, crevice and general corrosion. This material has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and a low coefficient of thermal expansion, further, the impact strength is also high
