Hastelloy C-276 (UNS N10276)
Introduction of Hastelloy C-276
Hastelloy C-276 (UNS N10276), also known as Alloy C276, is a nickel molybdenum chromium alloy renowned for its exceptional corrosion resistance in some of the most aggressive industrial environments. The alloy offers excellent resistance to oxidizing and reducing media, making it one of the most versatile corrosion resistant alloys available today.
Due to its outstanding resistance to pitting, crevice corrosion, stress corrosion cracking, wet chlorine, ferric chloride, sulfuric acid, and hydrochloric acid, Alloy C276 is widely used in chemical processing equipment, pollution control systems, offshore platforms, pharmaceutical plants, and oil & gas facilities.
