SPECIFICATION FOR NICKEL AND NICKEL-ALLOY BARE WELDING ELECTRODES AND RODS

A7.9.3 ERNiFeCr-3. The nominal composition (wt %) of filler metal of this classification is 47 Ni, 23 Fe, 20.5 Cr, 2

Cu, 3 Nb, 3.2 Mo, and 1.5 Ti. Filler metal of this classification is used for welding nickel-iron-chromium alloy approved by NACE MR0175/ISO 15156-3 for oil and gas applications (having UNS number N09945 or N09946) to itself, to steels, and to weld overlay steels using the GTAW and GMAW processes. The weld metal will age harden on heat treatment. For specific information concerning age hardening consult the supplier or the supplier’s technical literature. The alloy is resistant to sulfide-induced stress corrosion cracking and stress cracking in hydrogen sulfide environments.
