INC625-116-10 - Inconel 625 TIG Rod 1/16" - ERNiCrMo-3 Nickel Alloy Filler Metal

Premium Inconel 625 TIG Wire (ERNiCrMo-3) for Critical Applications

The Josef Gas Inconel 625 TIG Wire (AWS Class ERNiCrMo-3) is a high-performance nickel-chromium-molybdenum alloy filler metal designed for the most demanding industrial environments. Engineered to provide exceptional resistance to pitting, crevice corrosion, and stress-corrosion cracking, this 1/16" (1.6mm) diameter wire is the industry standard for welding Inconel 625, Inconel 825, and a variety of other high-alloy steels. Its unique chemical composition, fortified with niobium, ensures high tensile strength and toughness without the need for heat treatment, making it an indispensable consumable for fabrication in aerospace, marine, chemical processing, and power generation sectors.

Technical Performance and Metallurgy

This filler metal is formulated to meet the rigorous requirements of AWS A5.14. The high nickel content provides immunity to chloride-ion stress-corrosion cracking, while the molybdenum and niobium stiffen the alloy matrix, delivering high strength across a vast temperature range—from cryogenic lows up to 1800°F (982°C). It is particularly effective for overlay cladding on carbon steel to improve surface corrosion resistance and for joining dissimilar metals, such as stainless steels to nickel alloys or carbon steels. The wire exhibits low dilution characteristics and produces sound, defect-free welds with excellent mechanical properties.

Industrial Applications

Inconel 625 is widely utilized in pollution control equipment, such as scrubbers and flue gas desulfurization systems, due to its resistance to sulfuric and phosphoric acids. In the offshore oil and gas industry, it is the material of choice for piping systems and sour gas service components exposed to high pressure and corrosive seawater. Additionally, its high fatigue strength makes it suitable for bellows, expansion joints, and aircraft ducting systems. This 10lb tube packaging ensures that professionals have an ample supply of clean, straight-cut lengths for precision TIG welding operations.

Quality Assurance

Every batch of our ERNiCrMo-3 wire is manufactured under strict quality control protocols to ensure consistent diameter, surface cleanliness, and alloy composition. The 36-inch cut lengths are stamped or flagged for easy identification, preventing material mix-ups in critical shop environments. When reliability and performance in extreme environments are non-negotiable, this Inconel 625 filler metal delivers the results required by certified welding inspectors and engineers.
