C-276 Hastelloy alloy belongs to the nickel-molybdenum-chromium-iron-tungsten nickel-based alloy, which is the most corrosion-resistant one among modern metal materials. It is mainly resistant to wet chlorine, various oxidizing chlorides, chloride salt solutions, sulfuric acid and oxidizing salts, and has good corrosion resistance in low-temperature and medium-temperature hydrochloric acid. Therefore, in the past thirty years, it has been widely used in harsh corrosive environments such as chemical industry, petrochemical industry, flue gas desulfurization, pulp and papermaking, environmental protection and other industrial fields.
The various corrosion data of Hastelloy C-276 alloy are typical, but they cannot be used as specifications, especially in unknown environments. Materials must be selected after testing. Hastelloy C-276 alloy does not contain enough Cr to resist corrosion in strong oxidizing environments, such as hot concentrated nitric acid. This alloy is mainly produced for chemical process environments, especially in the presence of mixed acids, such as the discharge pipe of the flue gas desulfurization system.
The mechanical properties of Hastelloy alloy are very outstanding. It has the characteristics of high strength and high toughness, so it is difficult to machine. When the deformation rate reaches 15%, it is about twice that of 18-8 stainless steel. Hastelloy alloy also has a medium-temperature sensitization zone, and its sensitization tendency increases with the increase of deformation rate. When the temperature is high, Hastelloy alloy easily absorbs harmful elements, which reduces its mechanical properties and corrosion resistance.
