What is UNS S31260 Duplex Steel?

UNS S31260 is a high-performance duplex stainless-steel grade featuring a balanced ferritic-austenitic microstructure. This unique composition delivers nearly twice the strength of conventional austenitic stainless steels while providing excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. The alloy is specifically engineered for aggressive environments where both strength and corrosion resistance are essential.
