The 2205 alloy is a 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 resistance to stress corrosion. The 2205 duplex stainless steel has twice the yield strength of austenitic stainless steel. This feature allows designers to reduce weight when designing products, making this alloy more cost-effective than 316,317L. This alloy is especially suitable for use in the temperature range of -50°F / +600°F.
