This versatile nickel alloy welding wire is ideal for joining and overlaying components made of Inconel alloys, nickel-chromium-iron materials, and dissimilar metals. It maintains structural integrity at elevated temperatures, making it suitable for demanding industries such as petrochemical processing, power generation, heat exchangers, and furnace equipment. Its metallurgical composition promotes resistance to carburization, scaling, and chloride-induced stress corrosion cracking, ensuring long-term durability under mechanical and thermal stress.
The ERNiCrFe-12 filler metal provides a precise chemical balance of nickel, chromium, and iron, resulting in a tough, stable weld deposit that resists cracking and maintains corrosion resistance in both oxidizing and reducing atmospheres. This wire performs exceptionally well in welding joints exposed to high-temperature gases or combustion byproducts, maintaining mechanical properties without degradation. When used for overlaying or cladding, it enhances surface resistance to oxidation and corrosion, extending the service life of components in aggressive environments.

Welding Processes
MIG (GMAW) and TIG (GTAW) — suitable for manual, semi-automatic and automated operations.
Available Forms & Diameters
Solid wire on spools and coils; common diameters: 0.8 mm (0.030"), 1.0 mm (0.040"), 1.2 mm (0.045"), 1.6 mm (1/16"), 2.4 mm (3/32") — custom sizes available on request.
Recommended Shielding Gases
High-purity Argon for TIG; Argon or Argon/Helium blends for MIG; small additions of O₂ or CO₂ may be used for transfer characteristics in specified applications — follow welding procedure specification.
Typical Applications
Cladding, overlay and joining of nickel-chromium-iron alloys and Inconel-type materials; petrochemical process equipment, heat exchangers, furnace components, power generation, and wherever high temperature corrosion and oxidation resistance are required.
Corrosion & High-Temperature Performance
Good resistance to oxidation, carburization and chloride-induced attack at elevated temperatures; maintains mechanical stability in oxidizing and reducing atmospheres typical of industrial service.
Heat Treatment
Generally used in the as-welded condition for most applications; post-weld heat treatment depends on base material and component requirements — consult metallurgical guidance for critical components.
Packaging
Wire supplied on sealed spools with desiccant, standard spool weights (e.g., 5 kg, 15 kg, 20 kg) or as customer-specified coils; labeled with batch and heat number for traceability.
Surface Condition & Cleanliness
Bright, oil-free, and oxidation-minimized surface finish to ensure consistent feeding and clean weld deposition; stored and packaged to prevent moisture pick-up.
Quality & Certification
Manufactured under controlled quality assurance with traceable lot identification. Conformity to ASTM A5.14 available upon request; full material test report (MTR) and chemical analysis can be provided.
Handling & Storage Recommendations
Store in a dry, temperature-stable environment. Avoid prolonged exposure to moisture and contaminants. Use within recommended shelf-life for optimal welding performance.
