2205 Duplex Stainless Steel Plate - UNS S32205

2205 is a duplex stainless steel, with a chemical composition of nearly equal proportions of austenite and ferrite. This combination allows the alloy to be stronger and tougher than standard austenitic steels. Duplex stainless steels like 2205 also maintain good weldability in their thickest sections, and they are much more resistant to stress corrosion cracking than standard austenitic steels.
