Super Duplex UNS S32760 has a microstructure of approximately 50% austenite and 50% ferrite and has been designed to cope well in aggressive and harsh environments. UNS S32760 contains high molybdenum, chromium and nitrogen which help towards the outstanding resistance to pitting and crevice corrosion in seawater as well as other chloride containing environments, and excellent resistance to SCC (stress corrosion cracking).
