ERNiCr-3 MIG & TIG Welding Wire

Metals And Welding Specialities offers high-quality ERNiCr-3 MIG & TIG Welding Wire welding wires designed for superior performance across demanding industrial applications. This premium nickel-chromium alloy filler metal provides exceptional resistance to corrosion and oxidation, making it the preferred choice for welding nickel-based alloys and dissimilar metals. Known under the UNS N06082 designation and conforming to ASTM A494 Grade CW-6M and ISO 18274: S Ni 6082 (NiCr20Mo9Nb), this filler ensures consistent weld integrity even in extreme environments such as chemical plants, marine systems, and power generation units.

The ERNiCr-3 wire from Metals And Welding Specialities is engineered for both MIG (GMAW) and TIG (GTAW) welding processes. It delivers smooth arc stability, low spatter levels, and excellent weld pool control, enabling welders to achieve clean, strong joints with minimal post-weld finishing. The composition includes a precise balance of nickel, chromium, iron, and trace elements that promote resistance to pitting and stress-corrosion cracking, particularly in oxidizing and reducing environments. This makes it ideal for joining Inconel 600, Inconel 601, and Inconel 690 alloys, as well as for overlaying and cladding carbon or stainless steels where superior corrosion resistance is needed.

Applications of AWS Class ERNiCr-3 filler wires span across industries requiring high heat and corrosion endurance. These include nuclear reactors, gas turbines, chemical processing equipment, and aerospace components. The filler metal maintains high strength and ductility even under cyclic thermal stresses, ensuring reliability in service conditions involving fluctuating temperatures and aggressive chemicals. Metals And Welding Specialities ensures every spool or rod meets stringent quality standards through advanced testing and precision manufacturing, guaranteeing weld metal purity and mechanical stability.

Another key advantage of ERNiCr-3 is its versatility in joining dissimilar metals. It is widely used for welding between nickel-chromium alloys and stainless steels, offering outstanding metallurgical compatibility. This property minimizes the risk of intergranular corrosion and thermal fatigue, improving service life in pressure vessels, pipelines, and heat exchangers. Welders appreciate its easy arc initiation and excellent bead appearance, while engineers value its predictable performance under pressure and heat.

Metals And Welding Specialities stands as a trusted supplier of ERNiCr-3 MIG & TIG welding wires due to its commitment to precision, quality assurance, and technical excellence. Each product is manufactured using premium-grade raw materials and packed with care to preserve cleanliness and weldability. Whether for critical repair work or high-performance fabrication, Metals And Welding Specialities’ AWS Class ERNiCr-3 ensures dependable results every time.
