about us
1.Introduction
Hastelloy C276 is a nickel-molybdenum-chromiumsuperalloywith 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 low carbon content
minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures.
This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone,
thus making it suitable for most chemical process application in an as welded condition.
Although there are several variations of the Hastelloy nickel alloy, Hastelloy C-276 is by far the most
widely used.
Alloy C-276 is widely used in the most severe environments such as chemical processing,
pollution control,pulp and paper production, industrial and municipal waste treatment, and recovery of
sour natural gas.
