The ESAB OK Tigrod 309L is a high-performance, corrosion-resistant chromium-nickel TIG welding rod designed for the Gas Tungsten Arc Welding (GTAW) process. Classified as AWS ER309L, this filler metal features a nominal composition of 23% Chromium and 13% Nickel. This specific alloy chemistry makes it the industry standard for welding dissimilar metals, such as joining stainless steel (AISI 304, 316, etc.) to unalloyed or low-alloy carbon steels. The "L" designation indicates a low carbon content (maximum 0.03%), which is critical for preventing carbide precipitation during the welding process, thereby maintaining the corrosion resistance of the weld zone and reducing the risk of intergranular corrosion.
Industrial fabricators and MRO professionals rely on the OK Tigrod 309L for its superior metallurgical properties. It is frequently used to deposit buffer layers on mild steel components before applying a final overlay of 308L or 316L stainless steel. This technique ensures a sound metallurgical bond and prevents dilution issues that could compromise the final cladding. The rod produces a weld metal with a ferrite content of approximately FN 10, providing excellent resistance to hot cracking, a common issue in fully austenitic weld deposits.
Supplied in a robust 5kg tube, these 1.6mm diameter rods are precision-manufactured to ensure consistent diameter and surface cleanliness. This attention to manufacturing quality translates to stable arc characteristics, excellent fluidity, and a bead profile that requires minimal post-weld cleaning. The ESAB OK Tigrod 309L is suitable for applications in the chemical, petrochemical, and power generation industries, as well as general fabrication where high-integrity dissimilar joints are required.
