SUPER DUPLEX 2507 / UNS S32760

An excellent corrosion resistance with a combination of nickel-molyoaenum-chromium duplex with addition of tungsten suits a wide range of severe environments. Properties include robustness, attrition resistence in a widespread number of ordinary and inorganic acids. At long last it includes high obduracy to hard salts and compete against erosion in various non-oxidizing acids. The substance structure of S32750 and S32760 are relative; nevertheless, the last contains rather more copper and tungsten.

Resistant to pitting and crevice corrosion. Contains low carbon contents which minimizes carbide precipitation in soldered structures while being welded. Used in pollution control, chemical processing pulp and paper production and waste treatment Standard product forms are round, forging stock, tube, pipe, plate, sheet, strip and wire.
