Duplex stainless steels are known for having a two-phase microstructure consisting of 50% austenitic grains and 50% ferritic stainless steel. This sort of steel has a variety of advantages and is often selected owing to its enhanced strength over standard ferritic or austenitic stainless steels – it is about twice as powerful as these metals. Due to its enhanced yield strength, it is possible to create thinner parts of stainless duplex steels, resulting in important weight savings. For structural applications and pressure vessels, this makes duplex stainless steel a common option.
Duplex 2205 steel is widely used in applications requiring excellent resistance and strength to corrosion. The stainless steel grade S31803 has experienced several changes arising in UNS S32205. This grade provides higher corrosion resistance. At temperatures above 300 ° C, this grade's brittle micro-constituents are precipitated, and the micro-constituents undergo ductile-to-brittle transition at temperatures below -50 ° C; hence, this grade of stainless steel is not suitable for use at these temperatures. In the as-annealed and as-welded conditions, Duplex 2304 Steel has excellent intergranular corrosion resistance due to its low carbon content. In the hot rolling unsealed condition, some intergranular attack may occur.
