C276 Alloy
C276 Alloy is a nickel-molbdenum-chrome alloy with an addition of tungsten. The material was designed to have high resistance to severe corrosive media. With the high molybdenum  and nickel provide good corrosion resistance in reducing environments and is particularly resistant to pitting and crevice corrosion. The chromium resists oxidation C276 Alloy maintains high strength at room temperatures as well as elevated temperatures.
