Application
ENiCrMo-3 (Alloy 112) is an electrode that is used to weld nickel-chromium-molybdenum alloys. Its applications include dissimilar joints between nickel-chromium-molybdenum alloys to either stainless steels, carbon steels or low alloy steels.

These electrodes are used in applications where the temperature ranges up to 1800ºF.
