Product Description
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.
Key Features
- Excellent high-temperature strength, fatigue resistance, and stress rupture properties
- Precipitation-hardenable alloy with niobium and titanium for enhanced mechanical performance
- Outstanding resistance to corrosion, oxidation, and heat scaling
- Designed for welding Inconel 718 and similar age-hardenable nickel alloys
- Suitable for aerospace, turbine, cryogenic, and nuclear components
- Smooth arc, minimal spatter, and crack-resistant welds
- Conforms to AWS A5.14 ERNiFeCr-2 and UNS N07718 standards
Common Names / Designations
- AWS: ERNiFeCr-2
- UNS: N07718
- Equivalent Alloy: Inconel 718
- Other Names: Alloy 718 welding wire, 2.4668 TIG wire, Nickel 718 MIG rod
Typical Applications
- Jet engine components (discs, blades, fasteners)
- Gas turbines and aerospace hardware
- Cryogenic storage tanks and equipment
