ERNiCrMo-14 welding wire is used for welding low-carbon nickel-chromium-molybdenum alloys (especially UNS N06686) and nickel-chromium-molybdenum stainless steel. It is also used for the welding of low-carbon nickel-chromium-molybdenum alloy composite steel surface, the welding of low-carbon nickel-chromium-molybdenum and steel and other nickel-based alloys, and the surfacing of the nickel-chromium-molybdenum-tungsten layer on the steel surface.
