Hunan Hemway Steel Co., Ltd.
Alloy 2205 is a duplex stainless steel with a nitrogen addition for improved corrosion resistance, particularly where welding is required. In the annealed condition, alloy 2205 has more than twice the strength of conventional austenitic stainless steels and, in many environments, exhibits corrosion resistance superior to alloy 316. It is the most widely used of the duplex stainless steels. Alloy 2205 is commonly referred to as 22 Chrome and the universal designation of UNS S31803.
