Data SheetERNiCrMo-4
ERNiCrMo-4 can be used for welding nickel-chromium-molybdenum base materials to itself and welding of materials of similar chemical composition, as well as dissimilar material of nickel base alloys, steels and stainless steels.
ERNiCrMo-4 of its high molybdenum content it offers excellent resistance to stress corrosion cracking, pitting, and crevice corrosion, thus it is often used for cladding.
ERNiCrMo-4 often used for groove welding of 9% nickel steels in the production of LGN storage tanks.
