Alloy C276 Nickel Pipe

Alloy C276 nickel pipe is made from a nickel-molybdenum-chromium alloy with addition of tungsten having excellent corrosion resistance in a wide range of severe environments. The high molybdenum content makes this 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.

Typical applications: pollution control, chemical processing, pulp and paper production, and waste treatment.
