3.Product Features
- AWS A5.14 ERNiFeCr-2 Classification: Exact chemistry match for Inconel 718 base metal, ensuring weld deposits retain the same high-temperature strength and corrosion resistance as the parent material.
- Precision Layer Wound Spooling: Diamond-precision layer wound for smooth, uninterrupted wire feeding with zero tangling or bird-nesting.
- Vacuum-Sealed Packaging: Each spool is vacuum-packed with desiccant to prevent moisture absorption and oxidation during storage and shipping.
- Clean Weld Deposit: Low impurity levels (S, P, O, N) guarantee clean, crack-free weld beads suitable for radiographic inspection.
- Mill Test Certificate (MTC): Full chemical and mechanical traceability per EN 10204 3.1 included with every shipment.
4. Typical Applications
- Aerospace: Repair and fabrication of turbine discs, compressor blades, and combustion chambers
- Oil & Gas: Welding of downhole tools, valve bodies, and wellhead equipment in sour service environments
- Power Generation: Gas turbine hot-section component repair and overlay welding
- Nuclear: Reactor internals and structural component welding
- General Industry: Joining Inconel 718 to dissimilar alloys for high-temperature applications
