Alloy 2507 Stainless Steel
UNS S32750
Description
Alloy 2507 is a duplex (austenitic/ferritic) stainless steel that combines many of the most beneficial properties of ferritic and austenitic steels. Due to the high chromium and molybdenum content of the steel, it has excellent resistance to point corrosion, crevice corrosion and uniform corrosion. And the duplex microstructure ensures that the steel has high stress corrosion rupture resistance and high mechanical strength. Alloy 2507 also has high thermal conductivity, a low coefficient of thermal expansion, and good weldability.
