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

• Super duplex 2507: Super duplex 2507 contains 25% chromium, 7% nickel, 4% molybdenum, and 0.25% nitrogen. It has excellent corrosion resistance in various environments, including seawater and acidic solutions. It has high strength and is often used in chemical processing, oil and gas, and marine applications.
• Super duplex Zeron 100: Super duplex Zeron 100 contains 25% chromium, 7% nickel, 3.5% molybdenum, and 0.5% copper. It has excellent corrosion resistance in harsh environments, such as high-temperature seawater, and is often used in oil and gas, chemical processing, and marine applications.

Super duplex steel products with these grades include pipes, tubes, sheets, plates, bars, fasteners, and fittings.
