Product DescriptionERNiCr-3 is a solid nickel-chromium alloy welding wire designed for
welding dissimilar metals, especially nickel alloys to stainless
steels and low-alloy steels. It is equivalent to Inconel® 82 and
classified under UNS N06082. The wire provides excellent mechanical
properties and superior resistance to oxidation and corrosion,
particularly in high-temperature service environments. Suitable for both TIG (GTAW) and MIG (GMAW) processes, ERNiCr-3
ensures smooth arc characteristics, minimal spatter, and strong,
crack-resistant welds. It is commonly used in petrochemical, power
generation, and nuclear industries where joint reliability under
thermal stress and chemical exposure is critical.
Key FeaturesExcellent resistance to oxidation, scaling, and corrosion Suitable for welding dissimilar metals (e.g., Ni alloys to
stainless steels or carbon steels) High tensile strength and creep resistance at elevated temperatures Stable arc with clean bead profile and low spatter Good resistance to cracking during welding and service Reliable metallurgical compatibility with a wide range of base
metals Conforms to AWS A5.14 ERNiCr-3 and relevant international standards Used in both overlay and joining applications
