Duplex 2507

Duplex 2507 (UNS S32750) is referred to as super duplex stainless steel. Applications include, but are not limeted to, chemical process, petrochemical, and seawater equipment. It has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion. The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion
