Application
DURAMAX NA117 (ENiCrCoMo-1) has a nominal composition (wt.-%) of 52 Ni, 23 Cr, 12 Co, 9 Mo, 2 Fe, 1.5 Mn. Electrodes of this classification are used for welding Ni-Cr-Co-Mo (nickel- chromium- cobalt-molybdenum) alloys (UNS Number N06617) to themselves and to steel and for surfacing steel with Ni-Cr-Co-Mo weld metal. The electrodes are also used for applications where optimum strength and oxidation resistance are required above 1500°F up to 2100°F, especially when welding on base metals of Ni-Fe-Cr (nickel-iron-chromium) alloys.
DMNA117 electrodes resists corrosion, pitting, and stress-corrosion cracking. It offers superb strength and high temperature oxidation resistance. Typical applications include furnace equipment, heat exchangers, pipelines, and industrial plants.
