ASTM B622 – Standard Specification For Seamless Nickel And Nickel-Cobalt Alloy Pipe And Tube
ASME B622 /ASME SB622 UNS N10276, A nickel-molybdenum-chromium-iron-tungsten alloy, Low C Ni-Cr-Mo alloy C-276, C276 exhibits excellent corrosion resistance in a wide range of severe environments.
Hastelloy C276 is a nickel-molybdenum-chromium superalloy with 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 applications 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.
