Duplex 2507 Forgings are dual phase austenitic-ferritic duplex components manufactured from alloy containing chromium, nickel and molybdenum with restricted carbon content and minimum PREN 42. SAF 2507 Forgings have high strength, resistance to pitting, stress corrosion cracking, erosion and corrosion fatigue, crevice corrosion resistant.
