SUPER DUPLEX 2507 / UNS S32750 / SUPER DUPLEX STEEL WNR 1.4410

A combination of nickel-molyoaenum-chromium having excellent corrosion resistance in severe environments due to the addition of tungsten in it. Duplex 2507 is highly resistant to pitting and crevice corrosion because of high molybdenum content present in it. The less carbon content lessens Carbide precipitation while soldering to sustain rust resistance in soldered objects. Has lower rate of thermal expansion. Suggested for applications up to 600°F

Used in Desalination Equipment, Chemical process pressure vessels, piping and heat exchangers, Oil and gas industry equipment, Offshore Oil production/technology, Pulp & Paper Mill Equipment, Marine Applications and Flue Gas Scrubbing Equipment. Standard product forms are round, forging stock, tube, pipe, plate, sheet, strip and wire.
