Super duplex steel is a type of duplex stainless steel that has higher corrosion resistance and mechanical strength than standard duplex steel. It contains a higher percentage of chromium, nickel, and molybdenum, as well as other alloying elements like nitrogen, copper, and tungsten. There are several grades of super duplex steel, each with unique properties that make them suitable for specific applications. Here is a brief description of super duplex steel products with grades
