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 the temperature range of-50 F/+600 F. For applications beyond this temperature range, this alloy can also be considered, but there are some restrictions, especially when it is applied to welded structures. ?
