Application
DURAMAX NA182 (ENiCrFe-3) has a nominal composition (wt.-%) of 65 Ni, 15 Cr, 8 Fe, 7.5 Mn, 2 Nb + Ta. Electrodes of this classification are used for welding nickel-chromium-iron alloys, for welding the clad side of joints on steel clad with nickel-chromium- iron alloy and for surfacing steel with nickel-chromium-iron weld metal, when comparatively high manganese contents are not detrimental. The electrodes may be used for applications at temperatures ranging from cryogenic
to around 900°F. These electrodes can also be used for welding steel to other nickel-base alloys. DMNA182 is designed for welding in harsh, corrosive environments, such as desalination plants, petrochemical facilities and power generation plants, and in temperature critical conditions, such as furnace equipment and pipe work.
