The properties and application fields of Hastelloy C-276 Overview: The alloy in the oxidation and reduction state and having excellent corrosion resistance, the majority of corrosive media. Excellent resistance to pitting, crevice corrosion and stress corrosion cracking. Alloy suitable for various industrial chemical processes containing oxidizing and reducing media. Higher molybdenum, chromium content of the alloy resistant to the erosion of chloride ions, tungsten elements are also further improve its corrosion resistance. Hastelloy C-276 is one of a few can be resistant to moist chlorine, hypochlorite and chlorine dioxide solution corrosion material, one of the significant corrosion resistance of the alloy having a high concentration of chloride salts (such as chlorine ferric chloride and copper chloride).
