1. Duplex stainless steel 2205 alloy, compared with 316L and 317L austenitic stainless steel,2205 alloy is superior in the performance of corrosion resistance and crack corrosion, it has a high corrosion resistance, compared with austenitic, its thermal expansion coefficient is lower, higher thermal conductivity.
2. Duplex stainless steel 2205 alloy has twice the compressive strength compared with austenitic stainless steel, and designers can reduce its weight compared with 316L and 317L.The 2205 alloy is particularly suitable for the temperature range of -50°F/+600°F, and can also be used at lower temperatures under strictly restricted conditions (especially for welded structures).
Chemical composition :C≤0.030, Mn≤2.00, Si≤1.00, P≤0.030, S≤0.020, Cr 22.0~23.0, Ni 4.5~6.5, Mo 3.0~ 3.5n 0.14~0.20(austenitic iron body type)
2205 dual phase steel
Duplex stainless steel 2205 alloy is 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.
