* Alloy C276 is a nickel-chromium-molybdenum alloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. The high nickel and molybdenum contents make the nickel steel alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. The N10276 alloy also has good high temperature strength and moderate oxidation resistance although the alloy will eventually form embrittling high temperature precipitates. Although there are several variations, alloy C276 is the most widely used. * Chemical and petrochemical processing, pollution control, waste treatment, pulp and paper, sour gas applications (NACE MR0175), flue gas desulfurization (FGD).
