Product Description

Product Details

Duplex 2205 stainless steel (UNS S32205 formerly known as UNS S31803 and commonly known as “alloy 2205”) has a mixed microstructure of austenite and ferrite, and is a two-phase alloy based on the Fe-Cr-Ni series. Alloy 2205 material has lower nickel and molybdenum contents than austenitic stainless steel and have similar corrosion resistance. Because the price of Ni and Mo is relatively high, duplex stainless steel 2205 is often regarded as a cost-effective alternative to austenitic stainless steel.

Compared with the conventional 300 series stainless steel (e.g. SS 304, SS 316, SS 301, SS 904L, and 303, etc.), the special advantages of duplex 2205 stainless steel are strength (about twice that of austenitic stainless steel), and excellent resistance to chloride SCC and pitting corrosion. High yield strength has sufficient pressure and load capacity, and thin-wall materials can be made to greatly reduce weight.
