Super Duplex 2507


Super Duplex 2507 is a nickel-molybdenum-chromium alloy designed for applications demanding outstanding strength and corrosion resistance. The nitrogen, chromium, and high molybdenum content results in excellent resistance to crevice corrosion and chloride pitting. Super Duplex 2507 is often found in offshore platforms, heat exchangers, chemical processing, seawater equipment, and in the petrochemical industry.
