Dual phase stainless steel 2205 standard number: ASTM A240/A240M-01 Dual phase 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 excellent overall and local stress corrosion resistance.
The yield strength of 2205 duplex stainless steel is more than twice that of ordinary austenitic stainless steel, which allows designers to reduce weight when designing products and gives this alloy a price advantage over 316317L. This alloy is particularly suitable for the temperature range of -50 ° F/+600 ° F. Applications beyond this temperature range can also consider this alloy, but there are some limitations, especially when applied to welded structures.
Application fields:
·Pressure vessels, high-pressure storage tanks, high-pressure pipelines, heat exchangers (chemical processing industry).
·Oil and gas pipelines, heat exchanger fittings.
·Sewage treatment system.
·Paper pulp and paper industry classifiers, bleaching equipment, storage and processing systems.
·Rotary shafts, press rollers, blades, impellers, etc. in high-strength and corrosion-resistant environments.
·Cargo boxes for ships or trucks
·Food processing equipment
