Hastelloy C-276

Designated as UNS N10276 or DIN 2.4819, Hastelloy C-276 (also known as Alloy C-276), is a nickel-molybdenum-chromium alloy with an addition of tungsten having excellent corrosion resistance in a wide range of severe environments. The high molybdenum content makes the alloy especially resistant to pitting and crevice corrosion. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures. Hastelloy C-276 are typically used in a variety of industries such as pollution control, chemical processing, pulp and paper production, and waste treatment, etc. Hebei Metals provides Alloy C-276 materials in the form of plates, sheets, strips, billets, bars, wires, pipes, tubes, flanges, pipe fittings, and covered electrode.
