EXERNICRNMOH - Exocor ERNiCrMo-4 (C-276) TIG Rod 1/8" 10lb Tube

High-Performance Nickel-Chromium-Molybdenum TIG Filler Metal

The Exocor ERNiCrMo-4 is a premium Nickel-Chromium-Molybdenum welding rod designed for the Gas Tungsten Arc Welding (GTAW) process. Commonly referred to in the industry as C-276 (UNS N10276), this filler metal is engineered to provide exceptional resistance to a wide range of severe chemical environments. It is manufactured to meet AWS A5.14 specifications, ensuring consistent chemistry and mechanical properties for critical industrial applications.

The alloy composition includes significant additions of Molybdenum (15-17%) and Tungsten (3-4.5%), which are critical for its outstanding resistance to pitting and crevice corrosion. The low carbon content is a vital feature that minimizes the precipitation of carbides during welding, thereby maintaining the corrosion resistance of the as-welded structures without the need for post-weld heat treatment. This makes it an indispensable consumable for fabricating process equipment that handles aggressive media.

Technical Capabilities:

• Corrosion Resistance: Exhibits excellent stability in ferric and cupric chlorides, hot contaminated mineral acids, solvents, chlorine, and formic and acetic acids.
• Dissimilar Welding: Highly effective for joining nickel-based alloys to steel or stainless steel, as well as for cladding/surfacing steel to improve surface properties.
• Mechanical Strength: Provides robust tensile strength and ductility, suitable for high-stress environments.

This 1/8" (3.2mm) diameter rod is supplied in a 10lb tube, ideal for heavy fabrication tasks requiring substantial filler metal deposition. It is the preferred choice for engineers and metallurgists specifying materials for pollution control, chemical processing, and waste treatment sectors.
