Composite stainless steel consisting of 2 1% 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, which enables designers to reduce the weight when designing products, and also makes this alloy more competitive than 3 16, 3 17L. This alloy is especially suitable for -50 F/+600 F? In this temperature range. For applications beyond this temperature range, this alloy can also be considered, but there are some limitations, especially when applied to welded structures. ?

Compared with austenitic stainless steel, the compressive strength of duplex stainless steel is twice that of austenitic stainless steel. Compared with 3 16L and 3 17L, designers can reduce their weight. Alloy 2205 is especially suitable for the temperature range of-50 F/+600 F, and can also be used at lower temperatures under strict restrictions (especially for welded structures).
