308L32 - ER308L 1/8" Stainless TIG Filler Metal - 10lb Tube

High-Performance ER308L Austenitic Stainless Steel TIG Rods

The Central Wire ER308L TIG Welding Rod is a premium-grade consumable designed for the rigorous demands of industrial stainless steel fabrication. Engineered to meet AWS A5.9 and ASME SFA 5.9 classifications, this filler metal is the industry standard for joining Type 304 and 304L austenitic stainless steels. The "L" designation indicates a controlled low carbon content (maximum 0.03%), which is critical for minimizing carbide precipitation during the welding process. This feature significantly enhances the weld's resistance to intergranular corrosion, making it suitable for applications where the finished product will be exposed to corrosive environments or high temperatures.

With a diameter of 3.2mm (1/8 inch), this rod is optimized for welding medium to heavy gauge plates and piping. It provides a higher deposition rate compared to thinner diameters, allowing for efficient fill passes in multi-pass welding procedures. The chemical composition includes approximately 20% chromium and 10% nickel, ensuring that the weld metal matches the base material's mechanical properties and corrosion resistance. Central Wire Industries employs strict quality control measures during manufacturing, resulting in a rod with a clean, consistent surface finish that promotes stable arc characteristics and excellent wetting action.

Fabricators in the petrochemical, food and beverage, and power generation sectors rely on ER308L for its consistent performance and metallurgical integrity. The rods are supplied in a durable 10lb tube, protecting them from atmospheric moisture and physical damage during storage and transport. Each rod is typically stamped or identified to ensure material traceability on the shop floor, a vital requirement for code-compliant welding operations.
