ERNiCr-4 Welding Wire (Inconel 600 / UNS N06600) – Nickel-Chromium Alloy Filler Metal for Corrosion and Oxidation Resistance
Product Description
ERNiCr-4 is a solid nickel-chromium alloy welding wire specifically designed for welding base metals of similar composition such as Inconel® 600 (UNS N06600). Known for its excellent resistance to oxidation, corrosion, and carburization, this filler metal is ideal for use in high-temperature and chemically aggressive environments.
It is suitable for both TIG (GTAW) and MIG (GMAW) welding processes, offering stable arc characteristics, smooth bead formation, and good mechanical performance. ERNiCr-4 is widely used in the chemical processing, nuclear, aerospace, and marine industries.
