101282 - ER308L Stainless TIG Welding Rods - 2.5mm - 10lb Tube

Premium Grade ER308L Stainless Steel TIG Filler Metal

The Central Wire ER308L TIG Rod (Internal SKU: CWT308L25) is a high-performance austenitic stainless steel filler metal designed for the Gas Tungsten Arc Welding (GTAW) process. This product is manufactured to meet the rigorous requirements of AWS A5.9 specifications, ensuring consistent chemistry and mechanical properties. The 'L' designation indicates a 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 the preferred choice for welding ASTM 304 and 304L base metals.

With a diameter of 2.5mm, this rod provides excellent control for bridging gaps and managing heat input on medium-thickness sections. The chemical composition typically includes 19.5-22.0% Chromium and 9.0-11.0% Nickel, providing a weld deposit with excellent oxidation resistance and toughness. The rods are supplied in a durable 10lb tube, protecting the material from contamination and moisture, which is essential for maintaining X-ray quality welds. This filler metal is also suitable for welding stabilized grades like 321 and 347 if the service temperature does not exceed 750°F (400°C).

Technical professionals will appreciate the consistent diameter tolerance and surface cleanliness of Central Wire products. The rod's surface is free from drawing lubricants and oxides that could introduce porosity or inclusions into the weld pool. It is engineered to operate with 100% Argon shielding gas, producing a stable arc and a fluid puddle that wets out smoothly at the toes of the weld.
