About Alloy C276

Alloy C276, with a high nickel contents, is immune to chloride-induced stress corrosion cracking. The high molybdenum and chromium contents allow the alloy to perform in oxidising, non-oxidising and mixed acids media, whilst exhibiting outstanding resistance to pitting and crevice corrosion attack. The addition of tungsten inhibits the development of pits. Finally, C276 is suitable for off-shore applications where hydrogen-sulphide(H2S) stress corrosion cracking resistance is essential.

In aggressive or corrosive environments when other alloys have failed, many companies have then turned to C276 alloy – one of the most corrosion resistant alloys on the market.

Industries where C276 is utilised are petrochemical and chemical processing, power generation, pharmaceutical, pulp and paper production and waste treatment to name a few.
