36308L030 - ER308L Stainless TIG Filler Rod .030 x 36 Inch

Premium Grade ER308L Stainless Steel TIG Rods

The Central Wire ER308L TIG Welding Rod in 0.030-inch diameter is a high-quality austenitic stainless steel filler metal designed for the Gas Tungsten Arc Welding (GTAW) process. This specific alloy is engineered to join Type 304 and 304L base metals, which are among the most common stainless steels used in industrial fabrication. The "L" designation indicates a low carbon content (maximum 0.03%), which is critical for minimizing the risk of carbide precipitation during the welding process. This feature significantly enhances the weld's resistance to intergranular corrosion without the need for post-weld heat treatment, making it an excellent choice for as-welded structures.

This 10lb tube of cut lengths offers a consistent chemical composition that meets or exceeds AWS A5.9 specifications. The 0.030" diameter is particularly specialized, catering to applications requiring low heat input and precision deposition on thin-gauge materials. The rod exhibits excellent toughness at cryogenic temperatures and maintains high strength and corrosion resistance in various service environments. Metallurgically, the deposit provides a ferrite number typically between 8 and 12, ensuring high resistance to hot cracking while maintaining ductility.

Central Wire's manufacturing process ensures a clean, contaminant-free surface finish. This attention to surface quality promotes stable arc characteristics and reduces the likelihood of porosity in the weld metal. The rods are straightened and cut to a standard 36-inch length, providing optimal handling for the welder. Whether used for pressure vessels, piping systems, or architectural components, this ER308L filler metal delivers reliable, code-compliant results.
