duplex 2205 stainless steel (UNS S32205 formerly known as UNS S31803, commonly referred to as "Alloy 2205") with a mixed microstructure of austenite and ferrite, is a two-phase alloy based on the Fe-Cr-Ni series and is the most widely used duplex stainless steel. The nickel and molybdenum content of 2205 alloy material is lower than that of austenitic stainless steel and has similar corrosion resistance. Due to the relatively high price of Ni and Mo, duplex stainless steel 2205 is often seen as a cost-effective alternative to austenitic stainless steel.
The special advantages of 2205 duplex stainless steel compared to traditional 300 series stainless steels such as SS 304, SS 316, SS 301, SS 904L and 303, etc., are strength (about twice that of austenitic stainless steel) and excellent resistance to chloride SCC and pitting. The high yield strength has sufficient pressure and bearing capacity, and can be made into thin-walled materials, greatly reducing weight.
