Corrosion resistance of Hastelloy C-276 alloy are nickel - molybdenum - chromium - iron - tungsten nickel-based alloys. It is the most modern corrosion resistant metal material of one kind. The main moisture chlorine, various oxidizing chloride, chloride salts, sulfuric acid and oxidizing salt, in low and medium temperature hydrochloric acid has very good corrosion resistance. Therefore, nearly three decades, corrosion in harsh environments, such as chemical, petrochemical, flue gas desulfurization, pulp and paper, and environmental protection industries have a very wide range of applications. Various corrosion data Hastelloy C-276 alloy has its typical, but can not be used as standard, especially in an unknown environment, it must be tested before they can selection. Hastelloy C-276 alloy is not enough to Cr oxidation resistant to corrosive environments, such as hot concentrated nitric acid. This alloy is produced mainly for the chemical process environment, especially in the presence of mixed acid conditions, such as flue gas desulfurization system discharge pipe. Hastelloy C-276 alloy can be used as components of coal-fired flue gas desulfurization system, in this environment C-276 is the most corrosion resistant material. C-276 alloy, Ni and Mo make high levels of chloride stress corrosion cracking also has a strong resistance. Physical properties of density: 8.90g / cm3, specific heat: 425J / kg / k, elastic modulus: 205Gpa (21 ℃)
