What is 2205 Duplex Stainless Steel?
Duplex 2205 stainless steel is a nitrogen-enhanced duplex stainless steel containing chromium, molybdenum, and nickel. It offers approximately double the yield strength of standard austenitic stainless steels like 304 and 316, with improved resistance to chloride-induced stress corrosion cracking.
