Introduction:
2205 duplex stainless steel is a duplex stainless steel composed of 22% chromium, 3% molybdenum and 5-6% nickel nitrogen. It has high strength, good impact toughness and good overall and local stress corrosion resistance. Compared with 316L and 317L austenitic stainless steel, 2205 alloy has superior performance in pitting and crevice corrosion resistance. It has high corrosion resistance. Compared with austenite, its thermal expansion coefficient is lower and heat conduction. Higher sex.
The yield strength of 2205 is twice that of austenitic stainless steel. This feature enables designers to reduce weight when designing products, giving this alloy a more price advantage than 316 and 317L. 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 limitations, especially when applied to welded structures.
Application areas:
Pressure vessels, high-pressure storage tanks, high-pressure pipes, heat exchangers (chemical processing industry).
Oil and gas pipelines, heat exchanger fittings.
Sewage treatment system.
Pulp and paper industry classifiers, bleaching equipment, storage and processing systems.
Rotary shafts, press rolls, blades, impellers, etc. under high-strength and corrosion-resistant environments.
Cargo box of ship or truck
Food processing equipment
