Product Overview
Introduction to Hastelloy C276 / Alloy C276 / UNS N10276
Hastelloy C276 is one of the world's most widely used corrosion-resistant nickel alloys. Its unique combination of nickel, molybdenum, chromium, tungsten, and iron provides exceptional resistance to both oxidizing and reducing chemicals, making it suitable for applications where conventional stainless steels fail.
The alloy performs exceptionally well under harsh operating conditions involving hydrochloric acid, sulfuric acid, wet chlorine, ferric chloride, seawater, acidic gases, and chloride-containing solutions. It also exhibits excellent resistance to pitting corrosion, crevice corrosion, stress corrosion cracking, and localized corrosion.
Besides its outstanding corrosion resistance, Hastelloy C276 offers excellent weldability, high ductility, superior mechanical strength, and long service life even at elevated temperatures. These characteristics make it an ideal material for pressure vessels, reactors, heat exchangers, piping systems, scrubbers, storage tanks, valves, and other critical process equipment.
Today, engineers, project consultants, EPC contractors, and procurement professionals across industries rely on Hastelloy C276 supplied by Moksh Tubes & Fittings LLP whenever equipment must operate continuously in aggressive environments without compromising safety or performance.
