Duplex 2507 Exotic Alloy Pipe, Fittings, Flanges
Duplex 2507 pipe, valves, fittings, and fasteners (UNS S32750) are 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.
