Overview
2205 duplex stainless steel is composed of 22% chromium,3% molybdenum and 5-6% nickel nitrogen duplex stainless steel. It has high strength, good impact toughness and good overall and local resistance to stress corrosion. Compared with 316L and 317L austenitic stainless steel,2205 alloy in the resistance to point corrosion and gap corrosion performance is better, it has a high corrosion resistance, compared with austenite, its coefficient of thermal expansion is lower, higher thermal conductivity. The yield strength of 2205 is twice that of austenitic stainless steel, which allows designers to reduce weight when designing products, giving this alloy a price advantage over 316,317L. This alloy is particularly suitable for the -50°F/+600°F temperature range At the same time, it has also become an important engineering material, which is widely used in petrochemical industry, offshore and coastal facilities, oilfield equipment, paper making, shipbuilding environmental protection and other fields.
