S512511-017 - Hobart ER308/308L Stainless Steel TIG Rod 1/16" - 1lb Tube

Technical Overview of Hobart ER308/308L TIG Filler Metal

The Hobart S512511-017 is a premium quality stainless steel TIG welding rod designed for precision joining of austenitic stainless steels. Conforming to AWS A5.9 specifications, this filler metal carries a dual classification of ER308 and ER308L. The 'L' designation indicates a maximum carbon content of 0.03%, which is critical for minimizing carbide precipitation during the welding process. This feature significantly reduces the risk of intergranular corrosion, ensuring the longevity and integrity of the weldment in corrosive environments.

With a diameter of 1/16 inch (1.6mm) and a standard cut length of 36 inches, this rod is optimized for manual Gas Tungsten Arc Welding (GTAW) applications requiring fine control. The chemical composition includes chromium (19.5-22.0%) and nickel (9.0-11.0%), providing excellent resistance to scaling and oxidation. The rod is specifically formulated to weld base metals of similar composition, such as AISI types 301, 302, 304, 305, and 308. It is also suitable for welding type 321 and 347 stabilized grades when service temperatures do not exceed 750°F (399°C).

This product is packaged in a durable 1-pound tube, ensuring moisture protection and easy storage in industrial MRO environments. The rods are stamped for identification, aiding in quality control and material traceability compliance. Recommended welding parameters typically involve Direct Current Electrode Negative (DCEN) polarity with 100% Argon shielding gas to maintain a stable arc and clean puddle.
