Corrosion resistance and main use environment:
Hastelloy C-276 is a nickel-chromium-molybdenum alloy containing tungsten, an extremely low silicon carbon content, and is considered a universal corrosion resistant alloy. The alloy has the following characteristics: ①In the state of oxidation and reduction, it has excellent corrosion resistance to most corrosive media. ②It has excellent resistance to pitting corrosion, crevice corrosion and stress corrosion. The higher content of molybdenum and chromium makes the alloy resistant to chloride ion corrosion, and the tungsten element further improves the corrosion resistance. At the same time, C-276 alloy is one of the only materials resistant to the corrosion of wet chlorine gas, hypochlorite and chlorine dioxide solutions, and has a significant effect on high-concentration chloride salt solutions such as ferric chloride and cupric chloride. Corrosion resistance. It is suitable for sulfuric acid solutions of various concentrations and is one of the few materials that can be used in hot concentrated sulfuric acid solutions.
