Product Description
ERNiFeCr-2 is a nickel-iron-chromium solid welding wire conforming to AWS A5.14/A5.14M standards, primarily designed for welding nickel-based alloys such as Inconel® 718, 706, and X-750 . This welding wire features a unique chemical composition, with nickel content ranging from 50.0-55.0wt.%, chromium from 17.0-21.0wt.%, and key alloying elements including Niobium+Tantalum (4.75-5.50wt.%), Molybdenum (2.80-3.30wt.%), and Titanium (0.65-1.15wt.%) . Its strict compositional control ensures excellent mechanical properties and corrosion resistance. ERNiFeCr-2 is compatible with both GTAW (TIG) and GMAW (MIG) welding processes; however, caution is advised with high heat input processes like MIG, which may lead to microfissuring. This wire is widely used in applications requiring high strength, high-temperature resistance, and corrosion resistance, particularly in critical sectors such as aerospace and nuclear energy.
Features
▪ Superior Mechanical Properties and High-Temperature Stability: ERNiFeCr-2 weld metal exhibits outstanding mechanical properties. After age hardening, it achieves a tensile strength of up to 165,000 psi (1138 MPa) and an elongation of 27% .Its performance is comparable to that of the base metals, making it a preferred choice for high-strength applications. This alloy demonstrates good stability in both cryogenic and high-temperature environments, suitable for extreme thermal conditions
▪ Excellent Corrosion Resistance: The alloy composition of this welding wire provides good corrosion resistance, effectively resisting various corrosive media. This ensures the long-term reliability of welded structures in harsh environments
▪ Good Weldability: ERNiFeCr-2 welding wire is compatible with GTAW (TIG) and GMAW (MIG) processes, allowing for the formation of high-quality welds. Nevertheless, appropriate precautions should be taken when using high heat input processes to avoid potential microfissuring issues
Applications
▪ Due to its high strength, high-temperature resistance, and corrosion resistance, ERNiFeCr-2 welding wire is extensively used in the following demanding fields:
▪ Aerospace Industry: Utilized in the manufacturing of high-strength aircraft components, rocket engine parts, and spacecraft components exposed to cryogenic environments
▪ Nuclear Energy Industry: Employed in nuclear reactors for critical components requiring high reliability and corrosion resistance
▪ Petrochemical Industry: Used in equipment such as pumps and other industrial applications where corrosion resistance and high strength are essential
