00Cr15Ni60Mo16W4 TIG MIG Wire ERNiCrMo-4 C276 Nickel Base Alloy Welding Wire

Production Description

ERNiCrMo-4 (UNS N10276)

C-276 alloy Welding Wire is used for welding Hastelloy C276, nickel-based alloys and dissimilar materials, nickel alloys and steel or stainless steel, and also for cladding nickel-chromium-molybdenum alloy composite layers on steel. The alloy is resistant to corrosion by various acids and acid vapors. Due to its high molybdenum content, it has strong resistance to stress corrosion cracking, pitting and crevice corrosion. It is widely used in chemical container pipelines, pumps and valves, flue gas desulfurization in the power industry, and welding of 9% Ni steel for -196℃ applications.
