Super Duplex Stainless Steel

Super Duplex Stainless Steel

(UNS S32750)

Duplex Stainless Steels combine many beneficial properties of ferritic and austenitic materials to provide both high strength and good corrosion resistance.Due to their high chromium, molybdenum and nitrogen contents and duplex structure, these steels offer many benefits in comparison to 300 series austenitic grades: Good resistance to pitting and crevice corrosion. Excellent resistance to stress corrosion cracking. Good erosion and fatigue resistance. Good weldability and increased heat transfer.
