Duplex Stainless Steel
It has austenite + ferrite dual phase structure, Cr content is 18%~28%, Ni content is 3%~10%. Some steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N, which have the characteristics of high strength, pitting resistance, corrosion resistance, and fatigue resistance. Mainly used in oil refining, chemical fertilizer, paper making, petroleum, chemical industry, seawater and high tempe
