S32205 stainless steel welded steel pipe is formed by rolling 2205 stainless steel strip. 2205 steel pipe is duplex stainless steel composed of 21% chromium, 2.5% molybdenum, and 4.5% nickel-nitrogen alloy. It has high strength, good impact toughness, and good overall and local stress corrosion resistance. The yield strength of duplex stainless steel is twice that of austenitic stainless steel. This feature allows designers to reduce weight when designing products, making this alloy more than 316 and 317L. This alloy is particularly suitable for temperatures within the range of -50°F/+600°F. This alloy can also be considered for applications outside this temperature range, but there are some restrictions, especially when applied to welded structures.
