Hastelloy C276

C276 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. C276 alloy is suitable for various chemical process equipment containing oxidizing or reducing media. The higher molybdenum and chromium content and low carbon content make the alloy resistant to corrosion by chloride ions, and the addition of tungsten further improves its corrosion resistance. C276 is one of the only materials that is resistant to corrosion by wet chlorine, hypochlorite, and chlorine dioxide solutions. The alloy has significant corrosion resistance to high-concentration chloride salt solutions (such as ferric chloride and chlorine dioxide). copper).

Hastelloy C276 Features Supplement

This alloy has the following characteristics:

① It has excellent corrosion resistance to most corrosive media in both oxidizing and reducing atmospheres.

②Excellent resistance to pitting corrosion, crevice corrosion and stress corrosion.

The higher Mo and Cr content make the alloy resistant to chloride ion corrosion, and the W element further improves the corrosion resistance. At the same time, Hastelloy C-276 alloy is one of the only materials resistant to corrosion by moist chlorine, hypochlorite and chlorine dioxide solutions, and is resistant to high-concentration chloride solutions such as ferric chloride and copper chloride. Remarkable corrosion resistance. It is suitable for sulfuric acid solutions of various concentrations and is one of the few materials that can be used in hot concentrated sulfuric acid solutions.
