IANICROMO4000930TL - C-276 TIG Rod 3/32" - ERNiCrMo-4 Nickel Alloy Filler Metal

Premium ERNiCrMo-4 TIG Welding Rods for Extreme Environments

The Josef Gas C-276 (ERNiCrMo-4) TIG Rod is a high-performance nickel-chromium-molybdenum filler metal designed for the most demanding industrial applications. Engineered to meet AWS A5.14 specifications, this alloy is primarily used for welding base metals of similar composition, such as UNS N10276 (commonly known as Hastelloy C-276). Its unique chemical composition delivers outstanding resistance to a wide variety of severe chemical environments, making it an essential consumable for fabrication and maintenance in the chemical processing, pollution control, and waste treatment industries.

Unmatched Corrosion Resistance

One of the defining characteristics of the C-276 alloy is its exceptional resistance to pitting and crevice corrosion. The high molybdenum content (typically 15-17%) works in synergy with chromium and tungsten to provide robust protection against reducing and oxidizing acids. This TIG rod is particularly effective in environments containing ferric and cupric chlorides, hot contaminated mineral acids, solvents, chlorine, and chlorine-contaminated water (both organic and inorganic). It also exhibits excellent resistance to sulfide stress cracking and stress-corrosion cracking due to chloride ions, ensuring the structural integrity of welds in harsh conditions.

Versatile Application Range

Beyond welding C-276 base metals, this filler metal is highly versatile. It is frequently used for welding dissimilar metals, such as joining nickel-based alloys to steel or stainless steel. It is also suitable for cladding steel with C-276 weld metal. The 3/32" (2.4mm) diameter offers excellent control for root passes and fill passes on pipe and plate, providing a stable arc and clean weld puddle. Packaged in a durable 10lb tube, these 36-inch cut lengths are protected from moisture and contamination, ensuring they arrive ready for critical code work.

Technical Reliability

Fabricators rely on ERNiCrMo-4 for its mechanical stability and weldability. The low carbon content minimizes carbide precipitation during welding, maintaining corrosion resistance in as-welded structures. Whether you are repairing scrubbers, ducts, stacks, or pharmaceutical reaction vessels, the Josef Gas C-276 TIG rod delivers the consistent quality and metallurgical performance required for high-stakes projects.
