ERNiCrMo-4 (Alloy C276)
Alloy Type: A5.14, NICKEL AND NICKEL ALLOY Bare Electrodes and Welding Rods
ERNiCrMo-4 Nickel Alloy C276 is used for welding materials of similar chemical composition as well as dissimilar materials of nickel base alloys, steels and stainless steels. This alloy can also be used for cladding steel with nickel-chrome-molybdenum weld metal. The higher molybdenum content provides great resistance to stress corrosion cracking, pitting and crevice corrosion.
