Quick Answer: What Is Hastelloy C-276? Hastelloy C-276 (UNS N10276, W.Nr. 2.4819) is a nickel-molybdenum-chromium-tungsten alloy designed for outstanding resistance to an extensive range of severe corrosive environments. With approximately 16% molybdenum and 15% chromium, it provides exceptional resistance to pitting and crevice corrosion. It is one of the few materials capable of withstanding the corrosive effects of wet chlorine gas, hypochlorite, and chlorine dioxide. Its low carbon content minimizes carbide precipitation during welding, ensuring its integrity in as-welded structures.
Key standards: ASTM B574 (bar/rod), ASTM B622 (tube), ASTM B575 (plate/sheet), ASTM B564 (forgings), NACE MR0175.
