Caractéristiques: Hastelloy C-276 has excellent resistance to localized corrosion, stress corrosion cracking, and to both oxidizing and reducing media, thus making it suitable for a wide variety of chemical process environments, including ferric and cupric chlorides, hot contaminated media (organic and inorganic), formic and acetic acids, seawater and brine solutions. It is one of the few materials that withstands the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide.
Applications: Chemical processing, waste treatment, pollution control, pulp and paper production, and marine engineering.
