2205 stainless steel coil

2205 duplex steel has better abrasion resistance in the seawater environment, and is more suitable for application in seawater corrosion and wear environment than 316L stainless steel.

Product Description

2205 stainless steel increases the nitrogen content and enhances the stress corrosion resistance and pitting corrosion resistance in acidic media with high chloride ion concentration. Nitrogen is a strong austenite-forming element. When added to duplex stainless steel, it can not only increase the strength without significantly damaging the ductility of the stainless steel but also inhibit the precipitation of carbides.

The structural characteristics of 2205 duplex stainless steel are remarkable. In the greenhouse, austenite, and ferrite each account for about half of the steel solid solution, and both have the characteristics of the two-phase structure. It retains the characteristics of low thermal conductivity of ferritic stainless steel, resistance to pitting corrosion, crevices, and chloride stress corrosion, and also has austenitic stainless steel with good toughness, low brittle transition temperature, resistance to intergranular corrosion, mechanical properties, and welding performance.
