HASTELLOY C-276 (Alloy C276, 2.4819, UNS N10276)
HASTELLOY C276 (UNS N10276) is a nickel-chromium-molybdenum alloy with very high corrosion resistance to many chemical environments. Like other nickel alloys, Hastelloy C276 is also ductile, easy to shape and weld. It is resistant to oxidizing and non-oxidizing acids with its high chromium and molybdenum content.
Hastelloy C276 alloy plate, sheet, strip, billet, rod, wire, pipe, tube and welding wire are available in the form of electrodes. Hastelloy C276 is widely used in the chemical processing industry.
Hastelloy C276 has excellent wear resistance in a wide range of abrasive media with the addition of tungsten.

Hastelloy C276 alloy is suitable for Gas Metal Arc (GMA / MIG), Gas Tungsten Arc (GTA / TIG) and Shielded Metal Arc (SMA / Stick) welding processes. The forged products of the Hastelloy C276 alloy, unless otherwise indicated, are supplied annealed.
Cold work often does not affect the resistance of the Hastelloy C276 alloy to general corrosion and chloride-induced pitting and crack attack, while stress can affect resistance to corrosion cracking. For optimum corrosion performance, it is important that the cold-machined parts are re-annealed.
