HC276--Hastelloy C-276 is a nickel-chromium-molybdenum alloy containing tungsten, with extremely low silicon and carbon content, and is considered a universal corrosion-resistant alloy. It primarily resists wet chlorine, various oxidizing chlorides, chloride salt solutions, sulfuric acid, and oxidizing salts, exhibiting excellent corrosion resistance in both low and medium temperature hydrochloric acid. Therefore, over the past thirty years, it has been widely applied in harsh corrosive environments, such as in the chemical, petrochemical, flue gas desulfurization, pulp and paper, and environmental protection industries.
