Hastelloy C276 Pipe Fittings & Flanges

Made up of nickel-molybdenum-chromium with an incorporation of tungsten, Hastelloy C276 is a superalloy formatted to achieve exceptional corrosion resistance in a broad range of serious systems. The presence of high nickel and molybdenum elements provide the ability to resist pitting and crevice corrosion in reducing environments, while the chromium content enables to resist oxidizing agents. The less amount of carbon is to control carbon precipitation in the process of welding and helps to keep corrosion resistance in as-welded structures.
Eventhough Hastelloy nickel alloy is available in various different forms, but Hastelloy C276 is by far the most successfully and widely used form.
Proprties of Hastelloy C276
• Outstanding resistance o corrosion under reducing environments
• Resistant to strong oxidizing salt solutions like ferric and cupric chlorides
• Good resistance against restricted corrosion i.e. pitting and stress-corrosion cracking
• Rare ability to bear the corrosion of wet chlorine gas, hypochlorite and chlorine dioxide
• Abundance of nickel and molybdenum that provides corrosion resistance under reducing processes and low carbon content to lower the grain-boundary carbide precipitation in the welding process
