Hastelloy C276 is a nickel-molybdenum-chromium superalloy supplemented with tungsten, produced to have top-notch corrosion resistance in a vast range of critical environments. With high nickel and molybdenum contents, it makes nickel steel alloy resistant to crevice corrosion and pitting in reducing environments, while chromium channels resistance to oxidizing media. Hestelloy C276 suppliers and Hestelloy C276 manufacturers like Supreme Engineering Limited are at the forefront of the industry.
The low carbon content reduces carbide precipitation during welding to preserve corrosion resistance in as-welded structures. This is a nickel alloy that is resistant to the formation of grain boundary precipitates in the weld heat-affected area, making it a fitting alloy for chemical process application in an as-welded state. There are different variations of Hastelloy nickel alloy, but C276 is the most consumed.
