TG62512538 - Techalloy 625 1/8" TIG Welding Rod - ERNiCrMo-3 Nickel Alloy

Techalloy 625 Nickel Alloy TIG Rod - 1/8" (3.2mm)

Elevate your welding capabilities with Techalloy 625, a top-tier ERNiCrMo-3 TIG rod manufactured by Lincoln Electric's Techalloy division. This 3.2mm (1/8") filler metal is the industry standard for welding nickel-chromium-molybdenum alloys like Inconel 625. It is specifically formulated to combat extreme corrosion mechanisms, including pitting, crevice corrosion, and stress-corrosion cracking, making it indispensable for projects in harsh marine or chemical environments.

Beyond its corrosion resistance, Techalloy 625 is renowned for its mechanical properties. It delivers exceptional fatigue strength and oxidation resistance at temperatures ranging from cryogenic levels to 1800°F. This thermal stability allows it to be used in everything from cryogenic storage tanks to jet engine parts. The alloy's composition also makes it a superior choice for overlaying (cladding) on carbon steel to improve surface properties, extending the lifespan of equipment subject to wear and corrosion.

Welders appreciate the smooth running characteristics of Techalloy 625. It flows evenly, wets out the toes of the weld nicely, and provides a bead appearance that requires minimal post-weld cleaning. It is also the go-to filler for dissimilar joints, such as joining 9% nickel steel or super austenitic stainless steels to standard grades. Each 10lb tube contains 36-inch straight lengths, stamped or flagged for identification, ensuring you always have the right filler metal for your critical welding procedures.
