General attributes:

Duplex stainless steel has an α + γ dual-phase structure, so its performance characteristics are built of austenitic stainless steel and ferritic stainless steel. It is a type of stainless steel with high strength and best corrosion resistance. Generally, in the case of low C content, 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.
Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, significantly improved intergranular corrosion resistance and welding performance, while maintaining the 475 ° C brittleness and high thermal conductivity of ferritic stainless steel, and has superplasticity, etc. Features. Compared with austenitic stainless steel, the yield strength is significantly improved, and the resistance to intergranular corrosion, stress corrosion, corrosion fatigue and abrasion is significantly improved.
