ERNiCrMo-4 Nickel-Chromium-Moly Alloy Welding Wire

ERNiCrMo-4 Nickel-Chromium-Moly Alloy Welding Wire Introduction

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.

It can be used for gas-tungsten-arc and gas-metal-arc welding of INCONEL alloy C-276 and other nickel-chromium-molybdenum alloys. It is also used for surfacing of steel. The weld metal has excellent corrosion resistance in many aggressive media and is especially resistant to pitting and crevice corrosion.

Dissimilar-welding applications include welding INCONEL alloy C-276 to other nickel alloys, to stainless steels, and to low-alloy steels.
