Application
DURAMAX NA122 (ENiCrMo-10) has a nominal composition (wt.-%) of 56 Ni, 22 Cr, 13 Mo, 4 Fe, 3W. Electrodes of this classification are used for welding nickel chromium-molybdenum alloys, for the welding of the clad side of joints in steel clad with nickel-chromium-molybdenum alloy, to steel and to other nickel-base alloys; and for joining nickel-chromium-molybdenum alloys. Typical specifications for the nickel-chromium-molybdenum base metals are ASTM B 574, B 575, B 619, B 622, and B 626, all of which have UNS Number N06022.
DMNA122 is formulated for welding a wide array of industrial applications including power generation, petroleum and chemical plants, as well as offshore and marine facilities.
