The Weld Star Alloy C22 (ERNiCrMo-10) TIG wire is a high-performance nickel-chromium-molybdenum TIG filler designed for welding Alloy C22 and other corrosion-resistant nickel alloys such as Alloy 625, Alloy 825 and Alloy 926. It delivers weld deposits that excel in stress corrosion cracking resistance, pitting corrosion resistance and crevice corrosion resistance, making it ideal for the most demanding environments.
This filler is widely used for overlays, cladding of lower alloy steels, and dissimilar welding between super-austenitic alloys and stainless or low-alloy steels, particularly where aggressive corrosive media are encountered — such as chemical processing, offshore and petrochemical plants.
Key Features
