Alloy C-276 is a nickel-molybdenum-chromium alloy with additional tungsten. Alloy C-276 exhibits excellent resistance in a wide variety of chemical process environments including those with ferric and cupric chlorides, hot contaminated organic and inorganic media, chlorine, formic and acetic acids, seawater, brine and hypochlorite and chlorine dioxide solutions. In addition, alloy C-276 resists formation of grain boundary precipitates in the weld heat affected zone making it useful for most chemical processes in the as-welded condition.

This alloy has excellent resistance to pitting and stress corrosion cracking and oxidizing atmospheres up to 1040°C.
