Stainless Steel Sheet And Plate Product Description Duplex Stainless Steel (DSS) describes approximately 50% of ferrite and austenite and Steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N. Content, the Cr content is 18% to 28 percent, and the Ni content is 3% to 10%. Some Contains less than 30 percent of stainless steel. In the case of diminished C This type of steel unites the characteristics of ferritic and austenitic stainless steels. In comparison with ferrite, it has higher plasticity and toughness, no
