Alloy C276

UNS N10276

Description

A nickel-molybdenum-chromium alloy with an addition of tungsten used in chemical processing, pollution control, waste treatment, and pulp and paper production. The carbon content in alloy C-276 minimizes the carbide precipitation during welding to keep corrosion resistance in as-welded structures. The high molybdenum content makes C-276 particularly resistant to pitting and crevice corrosion.
