Hastelloy C-276

Hastelloy C276 is a nickel-molybdenum-chromium super alloy with an addition of tungsten and is 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.
