Application fields are of 2205 / UNS S31803:

2205 duplex stainless steel Coil and Strip are defined as smelting and manufacturing of stainless steel in which the ferrite phase and austenite are 50% each in comparison with the solidified structure. The actual comparative example is that ferrite accounts for 45-55%, and the corresponding austenite accounts for 55-45%. The excellent performance of 2205 duplex stainless steel is ensured by a proper proportion of the two-phase structure.
