2205 duplex stainless steel

Detail

2205 duplex stainless steel standard number: ASTM A240/A240M--01 Duplex stainless steel 2205 alloy is a composite stainless steel composed of 22% 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 2205 duplex stainless steel is more than double that of ordinary austenitic stainless steel, which allows designers to reduce weight when designing products. Advantages: high yield strength, sufficient toughness; excellent resistance to stress corrosion cracking; extremely high corrosion resistance; good local corrosion resistance
Application areas: pressure vessels, high pressure storage tanks, high pressure pipelines, heat exchangers, food processing equipment, oil and gas pipelines, sewage treatment systems, pulp and paper industry classifiers, bleaching equipment, etc.
