ERNiFeCr-2 Welding Wire (Inconel 718 / UNS N07718)

Nickel-Iron-Chromium alloy filler metal for high-strength, high-temperature applications

Product Description

ERNiFeCr-2 is a high-strength, corrosion-resistant nickel-iron-chromium alloy welding wire used for welding Inconel 718 and similar materials. It contains significant amounts of niobium (columbium), molybdenum, and titanium, which promote precipitation hardening and provide excellent tensile, fatigue, creep, and rupture strength.

This filler metal is ideal for demanding aerospace, power generation, and cryogenic applications that require mechanical strength at elevated temperatures. It is suited for both TIG (GTAW) and MIG (GMAW) welding processes and produces welds with good ductility, excellent strength, and resistance to cracking.
