Grade 2205 today has become one of the widely used duplex stainless steel (austenitic/ferritic) grades. It has today found in many applications because of being corrosion resistant and has high tensile strength. By many steel suppliers, the standard duplex S31803 composition has been greatly refined and it thus results in restricting the composition ranges that were authorized as UNS S32205. Grade S32205 is providing well-assured corrosion resistance. For duplex S31803 recently produced is complying with S32205. But grade 2205 is not suitable for the usage of the temperature ranging more than 300 Deg C. The reason is that it suffers from the precipitation of the brittle micro constituents.
