IANICRFE-125E - Exocor Inconel 182 Stick Electrode 1/8" (3.2mm) - 10lb Tube

Technical Overview of Exocor Inconel 182 (ENiCrFe-3)

The Exocor Inconel 182 (AWS classification ENiCrFe-3) is a premium coated stick electrode designed for the Shielded Metal Arc Welding (SMAW) of nickel-chromium-iron alloys. This 3.2mm (1/8") diameter electrode is formulated with a specific flux coating that facilitates welding in all positions while maintaining excellent arc stability and bead contour. The core wire chemistry is balanced to produce a deposit consisting primarily of nickel, chromium, and iron, with significant additions of manganese and niobium. The manganese content is a critical technical feature, as it effectively suppresses hot cracking and fissuring, which are common challenges when welding fully austenitic nickel alloys.

This consumable is engineered for joining Inconel 600, Incoloy 800, and similar Ni-Cr-Fe alloys to themselves or to carbon steels and stainless steels. It is also the industry standard for surfacing steel with nickel-chromium-iron weld metal. The niobium addition (plus tantalum) acts as a stabilizer, preventing chromium carbide precipitation and ensuring resistance to intergranular corrosion. The weld metal exhibits high strength and good ductility, with tensile strengths typically exceeding 80,000 psi and elongation values greater than 30%. It retains its mechanical properties from cryogenic temperatures up to approximately 900°F (482°C), making it suitable for a wide range of industrial environments.

Fabricators in the power generation, petrochemical, and nuclear industries rely on ENiCrFe-3 for its versatility in dissimilar metal welding. When joining carbon steel to stainless steel or nickel alloys, this electrode accommodates the dilution from the base metals without compromising the metallurgical integrity of the joint. The 10lb tube packaging ensures the electrodes remain protected from physical damage and moisture absorption, although proper storage in a rod oven is recommended to maintain low hydrogen levels and prevent porosity.

In summary, the Exocor Inconel 182 electrode provides a technically robust solution for complex alloy fabrication. Its compliance with AWS A5.11 standards ensures consistent performance and quality assurance for critical code work. Whether used for cladding side-walls of joints in clad steels or welding nickel-alloy piping systems, this electrode delivers the metallurgical reliability required by welding engineers and quality control inspectors.
