Corrosion resistance and main operating environment:
Hardy alloy C-276 is a tungsten-containing nickel-chromium-molybdenum alloy with very low silicon carbon content and is considered as a universal corrosion resistant alloy. The alloy has the following characteristics :1 in the oxidation and reduction atmosphere, it has excellent corrosion resistance to most corrosive media. Excellent resistance to pitting corrosion, crevice corrosion and stress corrosion. The high content of molybdenum and chromium makes the alloy resistant to chloride ion corrosion, and tungsten further improves the corrosion resistance. At the same time, C-276 alloy is one of the only materials that can resist the corrosion of moisture chlorine, hypochlorite and chlorine dioxide solution. It has remarkable corrosion resistance to high concentration chloride solution such as ferric chloride and copper chloride. Suitable for various concentrations of sulfuric acid solution, is one of the few materials can be used in hot concentrated sulfuric acid solution.
