IANICRM0400125OTL0 - Exocor ERNiCrMo-4 C-276 TIG Welding Rod 1/8" (3.2mm) - 10lb Tube

Premium Nickel-Chromium-Molybdenum TIG Rod for Extreme Environments

The Exocor C-276 (ERNiCrMo-4) TIG Welding Rod is a high-performance nickel-based consumable designed for the most demanding industrial applications. Engineered with a precise composition of nickel, molybdenum, and chromium, this alloy delivers exceptional resistance to a wide range of corrosive environments. It is specifically formulated to withstand both oxidizing and reducing media, making it an indispensable resource for maintenance and fabrication in chemical processing plants, pollution control facilities, and waste treatment sectors.

One of the defining characteristics of the C-276 alloy is its high molybdenum content, which provides superior resistance to pitting and crevice corrosion—common failure modes in chloride-rich environments. Additionally, the low carbon content ensures that grain boundary carbide precipitation is minimized during the welding process, thereby maintaining the corrosion resistance of the as-welded heat-affected zone. This makes Exocor C-276 an excellent choice for welding materials of similar composition as well as for joining dissimilar metals, such as nickel alloys to stainless or carbon steels.

This 1/8" (3.2mm) diameter rod is supplied in a 10 lb tube, ensuring ample material for substantial projects while protecting the rods from contamination. The 36-inch length is standard for manual TIG applications, offering excellent control and feedability. Whether used for fabricating flue gas desulfurization systems, pharmaceutical equipment, or petrochemical piping, Exocor C-276 ensures weld integrity and longevity in the harshest conditions.
