The metallurgical profile of duplex 2205 stainless steel, specifically UNS S31803, showcases a balanced microstructure of 50% austenite and 50% ferrite after undergoing solution annealing at temperatures between 1900°F and 1922°F (1040°C to 1080°C). Elevating the heat treatment beyond 2000°F might tip the balance towards an increased ferrite content. Like its duplex counterparts, the 2205 alloy is prone to intermetallic phase formations, particularly when subjected to temperatures ranging from 1300°F to 1800°F, with the most rapid precipitation at around 1600°F. To ensure the integrity of the ss 2205 material and its freedom from detrimental intermetallic phases, adherence to ASTM A923 testing standards is crucial.
