2205 Stainless Steel Coil

2205 stainless steel coil is a duplex stainless steel that combines the beneficial properties of both austenitic and ferritic stainless steels. also known as UNS S32205 or EN 1.4462.

It is a stainless steel composed of 22-23% chromium, 3-3.5% molybdenum, 4.5-6.5% nickel, and 0.14-0.2% nitrogen. It has high strength, good impact toughness, and good overall and local stress corrosion resistance.

It is particularly well-suited for applications in aggressive environments where both high strength and corrosion resistance are essential.

Available Forms and Sizes

2205 stainless steel coil is available in different surface finishes, including 2B, NO1, AB, and 8K.

It can be procured in various thicknesses, ranging from 0.3mm to 6mm for cold-rolled coils and up to 200mm for hot-rolled coils. The width and length can be customized according to customer requirements.
