Hastelloy C276 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. The high nickel and molybdenum contents make the nickel steel alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures. This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process application in an as welded condition.

Hastelloy C276 Main Characteristics

▪ Excellent corrosion resistance in reducing environments
▪ Exceptional resistance to strong solutions of oxidizing salts, such as ferric and cupric chlorides
▪ High nickel and molybdenum contents providing good corrosion resistance in reducing environments
▪ Low carbon content which minimizes grain-boundary carbide precipitation during welding to maintain resistance to corrosion in heat-affected zones of welded joints
▪ Resistance to localized corrosion such as pitting and stress-corrosion cracking
▪ One of few materials to withstand the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide
