2205 demister

Duplex stainless steel 2205 alloy is a duplex stainless steel made of 21% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. It has high strength, good impact toughness and good overall and local resistance to stress corrosion.

Features:

1. Duplex stainless steel 2205 alloy Compared with 316L and 317L austenitic stainless steel, 2205 alloy in the anti-pitting and crevice corrosion performance is superior, it has a high corrosion resistance, compared with austenite , It has a lower thermal expansion coefficient and higher thermal conductivity.

2. Duplex Stainless Steel 2205 has twice the compressive strength of austenitic stainless steel, allowing designers to reduce their weight compared to 316L and 317L. The 2205 alloy is especially suitable for use in the -50 ° F / + 600 ° F temperature range and can be used for lower temperatures under severe restrictions (especially for welded construction). Main components: 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 Mo3.0-3.5 N0.14-0.20 (austenite-ferrite type)

National standards: NAS 329J3L, UNS S32205 / S31803, DIN / EN 1.4462, ASTM A240, ASME SA-240.
