2205 duplex stainless steel is a ferritic-austenitic stainless steel composed of approximately 22% chromium, 3% molybdenum, and 5.5% nickel, with added nitrogen (0.14-0.20%) for enhanced strength and corrosion resistance .

This dual-phase microstructure, with roughly equal proportions of ferrite and austenite, combines the best properties of both phases: providing excellent corrosion resistance, high strength (twice that of standard austenitic grades), and good toughness. Its density is approximately 7.8 g/cm³.

Standards:

• ASTM/ASME: A240 UNS S32205/S31803
• EURONORM: 1.4462 X2CrNiMoN 22.5.3
• AFNOR: Z3 CrNi 22.05 AZ
• DIN: W.Nr 1.4462
