Hastelloy C276

Hastelloy 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 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.
