Hastelloy C-276 ingredient analysis
C-276 Hastelloy is a nickel-molybdenum-chromium-iron-tungsten nickel-based alloy and is the most corrosion-resistant among modern metal materials. Mainly resistant to wet chlorine, various oxidizing chlorides, chloride salt solutions, sulfuric acid and oxidizing salts, and has good corrosion resistance in low 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 paper making, 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, and materials must be selected after testing. There is not enough Cr in Hastelloy C-276 alloy to resist corrosion in strong oxidizing environments, such as hot concentrated nitric acid. The production of this alloy is mainly for chemical process environments, especially in the presence of mixed acids, such as the discharge pipe of flue gas desulfurization systems.
Hastelloy C-276 performance
The alloy has excellent corrosion resistance to most corrosive media in both oxidized and reduced states. Excellent resistance to pitting corrosion, crevice corrosion and stress corrosion cracking. Alloys are suitable for use in a variety of chemical process industries containing oxidizing and reducing media. The corrosion-resistant C276 high-temperature alloy sheet has high molybdenum and chromium content, which makes the alloy resistant to chloride ion erosion. The tungsten element also further improves its corrosion resistance.
