Product Description

ERNiCr-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.
