Overview of Hastelloy C-276 properties and application areas: This 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. The alloy is suitable for use in a variety of chemical process industries containing oxidizing and reducing media. The higher molybdenum and chromium content makes the alloy resistant to chloride ion erosion, and the tungsten element further improves its corrosion resistance. Hastelloy C-276 is one of the only materials resistant to corrosion by wet chlorine, hypochlorite and chlorine dioxide solutions. The alloy has significant corrosion resistance to high concentrations of chloride salt solutions (such as chlorine iron and copper chloride).

characteristic

Hastelloy C-276 is a tungsten-containing nickel-chromium-molybdenum alloy with extremely low silicon-carbon content. It is considered a universal anti-corrosion alloy and has good resistance to localized corrosion, stress corrosion cracking, oxidizing and reducing media. The ability can be applied to many chemical working conditions, such as ferric chloride, copper chloride, thermal pollution solutions (organic and inorganic), formic acid, acetic acid, seawater and brine solutions. It is one of the few materials resistant to corrosion by wet chlorine, hypochlorite and chlorine dioxide. Hastelloy C-276 is widely used in most chemical industries and high temperature environments.

Typical application areas:

1. Flue gas desulfurization system

2. Pickling and acid regeneration plants

3. Acetic acid and agricultural chemical production

4. Titanium dioxide production (chlorine method)

5. Electrolytic plating
