Pulp and paper industry
Alloy 2205 is a duplex stainless steel with high general, localized and stress corrosion resistance properties, high strengths and outstanding impact toughness. Developed primarily to combat common corrosion problems. Duplex is superior to 316L or 317L austenitic stainless steels in most corrosive environments. The duplex alloy 2205 structure consist of austenite pools surrounded by continuous ferrite phase and contains approximately 45% ferrite. It is the most widely use grade in the duplex family of stainless steels.
