Corrosion Resistance:Haynes Alloy C-276 is a tungsten-containing nickel-chromium-molybdenum alloy with extremely low silicon and carbon content, considered to be a universal corrosion-resistant alloy. The alloy exhibits the following characteristics: 1. Excellent corrosion resistance to most corrosive media in both oxidizing and reducing atmospheres. 2. Outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. Its higher molybdenum and chromium content enable it to resist corrosion by chloride ions, while the tungsten element further enhances its corrosion resistance. Additionally, C-276 alloy is one of the few materials resistant to corrosion by wet chlorine gas, hypochlorite, and chlorine dioxide solutions, as well as having significant resistance to highly concentrated chloride solutions such as ferric chloride and cupric chloride. It is suitable for various concentrations of sulfuric acid solutions and is one of the few materials that can be used in hot concentrated sulfuric acid solutions.

Applications:Desulfurization and denitrification in power plants, petrochemical equipment, coal chemical industry, fluorine chemical industry, fine chemical industry, PTA, aerospace manufacturing, marine platforms, seawater desalination, papermaking machinery, pharmaceutical equipment, heat exchange equipment, electrochemistry, metallurgy, nuclear energy, chlor-alkali, shipbuilding, cement manufacturing, composite boards, acetic acid and acetic anhydride, salt making, plate heat exchangers, bellows expansion joints, etc.
