Duplex Stainless Steel (DSS) refers to approximately 50% of ferrite and austenite, and generally contains less than 30% of stainless steel.

In the case where the C content is low, the Cr content is 18% to 28%, and the Ni content is 3% to 10%.

Some steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N.

This type of steel combines the characteristics of austenitic and ferritic stainless steels. Compared with ferrite, it has higher plasticity and toughness, no brittleness at room temperature,

significantly improved resistance to intergranular corrosion and welding performance, and at the same time retains iron. The 475°C brittleness

and high thermal conductivity of the ferritic stainless steel make it superplastic.

Compared with austenitic stainless steels, the strength and resistance to intergranular corrosion and chloride stress corrosion resistance are significantly improved.

Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel-stainless steel.

such as adding S, Ca, Se, Te and other elements. It has good cutting ability.
