Hastelloy C-276 is a nickel-molybdenum-chromium superalloy with tungsten expansion, designed to have excellent corrosion resistance in various severe conditions. The high nickel alloy and molybdenum content make the nickel steel alloy particularly resistant to pitting and crevice corrosion in reducing conditions, while chromium has the ability to resist oxidative media. The low carbon content minimizes carbide precipitation during the welding process to maintain the corrosion resistance of the welded structure. These nickel alloys can resist the accelerated formation of grain boundaries in the heat-affected zone during welding, making them suitable for most chemical process applications in the welded state.
