ERNiCrMo-10 Welding Wire (Hastelloy C22 / UNS N06022 / Nickel Alloy) – Premium NiCrMo Alloy Filler Metal for Critical Corrosive Environments
Product Description
ERNiCrMo-10 is a high-performance nickel-chromium-molybdenum alloy welding wire designed for the most severe corrosive environments. It is the designated filler metal for welding Hastelloy® C22 (UNS N06022) and other super austenitic and nickel alloys. With excellent resistance to oxidizing and reducing agents, this wire ensures superior weld integrity even in aggressive chemical environments.
It resists pitting, crevice corrosion, intergranular corrosion, and stress corrosion cracking across a broad range of temperatures and media. ERNiCrMo-10 is ideal for cladding, joining, or overlay welding in the chemical processing, pharmaceutical, pollution control, and marine industries. Compatible with TIG (GTAW) and MIG (GMAW) processes.
