2205 belongs to duplex stainless steel, and its strength is twice that of austenitic stainless steel.

Chemical composition: C≤0.030?Mn≤2.00?Si≤1.00?p≤0.030?S≤0.020?Cr?22.0～23.0?Ni?4.56.5?Mo3.0～3.5?N0. 14～0.20? Shanghai Xiangqia Metal Team is looking forward to your consultation!

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 stress corrosion resistance. The yield strength of duplex stainless steel is twice that of austenitic stainless steel. This feature allows designers to reduce weight when designing products, making this alloy more cost-effective than 316 and 317L. This alloy is particularly suitable for use in the -50°F/+600°F? temperature range. For applications outside this temperature range, this alloy can also be considered, but there are some limitations, especially when used in welded structures. ?

Compared with austenitic stainless steel, duplex stainless steel has twice the compressive strength. Compared with 316L and 317L, designers can reduce its weight. Alloy 2205 is particularly suitable for use in the -50°F/+600°F temperature range and can also be used at lower temperatures under severe restrictions (especially for welded structures).

Application areas?:

Pressure vessels, high-pressure storage tanks, high-pressure pipelines, heat exchangers (chemical processing industry).

Oil and natural gas pipelines, heat exchanger fittings.

Sewage treatment system.

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.
