S512346-I12 - Hobart ER316L 1/8" Stainless Steel TIG Welding Rods, 10lb Tube

Hobart ER316L Stainless Steel TIG Wire Overview

The Hobart ER316L Stainless Steel TIG Wire (SKU: S512346-I12) is a premium filler metal designed for the rigorous demands of industrial stainless steel fabrication. Engineered to meet AWS A5.9 specifications, this wire carries both ER316 and ER316L classifications, ensuring versatility and compliance with strict engineering standards. The 1/8-inch diameter and 36-inch cut lengths are optimized for manual Gas Tungsten Arc Welding (GTAW) processes, providing consistent feeding and arc stability.

A key metallurgical advantage of this alloy is the addition of molybdenum. This element significantly enhances the weld deposit's resistance to pitting corrosion, a common failure mode in chloride-rich environments. Furthermore, the "L" designation indicates a low carbon content (maximum 0.03%), which is critical for preventing carbide precipitation during the welding process. This feature preserves the corrosion resistance of the grain boundaries, mitigating the risk of intergranular corrosion—often referred to as weld decay—in the heat-affected zone. This makes the wire an excellent choice for welding Type 316 and 316L base metals.

Traceability and quality control are paramount in sectors such as petrochemical, pulp and paper, and food processing. To support these requirements, Hobart stamps each individual 36-inch rod with the AWS classification and the manufacturing lot number. This permanent identification ensures that welders and inspectors can verify the material used even after the packaging has been discarded. The product is supplied in a rigid 10lb tube, protecting the rods from contamination and physical damage during storage and transport.

Applications for the Hobart ER316L include the fabrication of chemical storage tanks, food and beverage processing equipment, and piping systems exposed to corrosive media. By choosing this high-performance filler metal, fabricators ensure the longevity and structural integrity of their stainless steel assemblies.
