Duplex 2205 is a ferritic-austenitic duplex stainless steel with approximately 22% chromium and 3% molybdenum. It combines the corrosion resistance of austenitic stainless steels with the higher strength of ferritic stainless steels. The common designation is UNS S31803 / S32205, with S32205 being the modern, tighter-composition version commonly specified for pressure-containing components.
For flanges, material/product specifications such as ASTM A182 / ASME SA182 F51/F60, together with the applicable flange dimensional standard such as ASME B16.5, should be specified rather than simply stating "Duplex 2205."
