S512337-I12 - Hobart ER316L Stainless Steel TIG Wire 3/32" x 36" - 10lb Tube

Premium Hobart ER316L Stainless Steel TIG Welding Wire

The Hobart ER316/ER316L Stainless Steel TIG Welding Wire is a high-performance filler metal engineered for the most demanding industrial applications. Supplied in a durable 10-pound tube, this 3/32-inch diameter wire is cut to standard 36-inch lengths, making it the ideal choice for manual Gas Tungsten Arc Welding (GTAW) processes. This product strictly adheres to AWS A5.9 specifications, carrying both ER316 and ER316L classifications, which ensures broad compatibility and versatility across a wide range of austenitic stainless steel fabrication projects.

A critical feature of this alloy is its specific chemical formulation, which includes molybdenum. This addition significantly enhances the weld deposit's resistance to pitting and crevice corrosion, a vital property for components exposed to salt, acids, or other chloride-containing environments. Furthermore, the "L" designation signifies a low carbon content (maximum 0.03%). This controlled chemistry is essential for preventing carbide precipitation at the grain boundaries during the thermal cycle of welding. By minimizing this risk, the wire preserves the corrosion resistance of the heat-affected zone, effectively mitigating intergranular corrosion which can compromise structural integrity over time.

For industries requiring rigorous quality control, such as petrochemical processing, food and beverage manufacturing, and power generation, traceability is paramount. Hobart addresses this by individually stamping each 36-inch rod with its AWS classification and manufacturing lot number. This feature ensures that welders and inspectors can instantly verify the material being used, facilitating code-compliant work and reducing the risk of costly material mix-ups. The wire is designed to be used with 100% Argon shielding gas, producing clean, defect-free welds with excellent bead aesthetics and smooth wetting characteristics.

Whether you are fabricating pressure vessels, complex piping systems, or sanitary pharmaceutical equipment, the Hobart ER316L TIG wire delivers consistent, high-quality performance. Its balanced chemical composition ensures a ferrite number that resists hot cracking while maintaining excellent ductility and toughness. This makes it the preferred choice for professional fabricators seeking reliability and superior results in challenging stainless steel joining applications.
