Product Overview
Hastelloy C22 (UNS N06022) Pipes, Sheets, Bars & Applications
MOKSH TUBES & FITTINGS LLP is a trusted supplier, exporter, importer, and stockist of Hastelloy C22 (Alloy C22 / UNS N06022) along with other nickel alloys such as Hastelloy C276 and Incoloy 825. We offer a complete range of products including Pipes & Tubes, Pipe Fittings, Flanges, Fasteners, Sheets & Plates, Coils, Wires, Round Bars, Flat Bars, Angles, Channels, Welding Rods, Wire Mesh, and other Custom Hastelloy solutions.
Unlike conventional stainless steels, Hastelloy alloys such as C22 and C276 are designed for highly corrosive and unpredictable environments. With excellent resistance to both oxidizing and reducing media, Hastelloy C22 provides superior protection against pitting, crevice corrosion, and stress corrosion cracking – even in aggressive chemical processes involving chlorides, wet chlorine gas, ferric and cupric salts, formic and acetic acids. Its unique chemistry and superior mechanical properties make it indispensable in chemical processing, marine, oil & gas, and other critical industries.
