Hastelloy® Alloy C276

Hastelloy® Alloy C276 is a tungsten added nickel-molybdenum-chromium super alloy designed to offer excellent corrosion resistance in wide range of severe environments. The chromium in Hastelloy® Alloy C276 conveys resistance to oxidizing media while high molybdenum and nickel content makes the nickel alloy specially resistant to pitting and crevice corrosion in reducing environments.
