Hastelloy C276, Alloy 276 (UNS N10276), A Nickel-Base Alloy with Resistance in a Wide Range of Aggressive Media.
Alloy 276 is a nickel-molybdenum-chromium-iron-tungsten alloy which is among the most corrosion resistant alloys currently available. Alloy 276 also has good high temperature strength and moderate oxidation resistance although the alloy will eventually form embrittling high temperature precipitates. Alloy 276 has been available for several years and has been used in ASME Boiler and Pressure Vessel related construction.

Spiral Wound Gasket C276 Style applications:
> Chemical and petrochemical processing;
> Flue gas desulfurizationg;
> Pulp and paper equipments;
> Industrial and municipal waste equipments.

General Corrosion:
> The alloy 276 is used in a range of environments from moderately oxidizing to strongly reducing;
> One application is in the more corrosive area of flue gas desulfurization system, such as outlet ducting;
> Alloy 276 compared to that of SS316 in the "GREEN DEATH" simulated scrubber solution
