Super Duplex Steel Bars and Forgings are high-alloy stainless steel products engineered for extreme corrosion resistance and exceptionally high mechanical strength. These materials provide outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in aggressive and chloride-rich environments.
Super Duplex Steel Bars & Forgings are manufactured through controlled hot rolling and forging processes to ensure superior toughness, structural integrity, and long service life in high-pressure and high-load applications.
Super Duplex Steel Bars and Forgings are available in premium super duplex grades designed to meet severe service conditions. The most commonly supplied grades include Super Duplex S32750 (UNS S32750) and Super Duplex S32760 (UNS S32760), offering high PREN values, excellent corrosion resistance, and outstanding mechanical strength.
