Product DescriptionERNiFeCr-1 is a nickel-iron-chromium alloy welding wire designed
for joining alloys of similar composition, such as Inconel 600 and
Inconel 690, and for dissimilar welding between nickel alloys and
stainless or low-alloy steels. It is particularly valued for its
excellent resistance to stress corrosion cracking, thermal fatigue,
and oxidation at elevated temperatures. Commonly used in nuclear power generation, chemical processing, and
heat exchanger fabrication, this wire ensures structural integrity
under high-stress environments. It is suitable for both TIG (GTAW)
and MIG (GMAW) welding processes.
Key FeaturesExcellent resistance to stress corrosion cracking, oxidation, and thermal fatigue High metallurgical compatibility with Inconel 600, 690, and
dissimilar base metals Stable arc, low spatter, and smooth bead appearance in TIG and MIG
welding Suitable for high-pressure steam environments and nuclear reactor components High mechanical strength and metallurgical stability at elevated
temperatures Conforms to AWS A5.14 ERNiFeCr-1 and UNS N08065
Common Names / DesignationsAWS: ERNiFeCr-1 UNS: N08065 Equivalent Alloys: Inconel 600/690 welding wire Other Names: Nickel Iron Chromium welding filler, Alloy 690 welding
