AWS Class ENiCrMo-4 coated electrodes are nickel-based electrodes alloyed primarily with chromium and molybdenum. This composition delivers excellent resistance to corrosion, oxidation, and high-temperature creep. The weld metal offers high tensile strength, good ductility, and superior toughness even at elevated temperatures. These electrodes provide stable arc characteristics, smooth slag removal, and crack-resistant welds. Their mechanical properties make them suitable for welding nickel alloys, stainless steels, and dissimilar metals where strength and metallurgical stability are essential.
