63060900 - Bonarc ER308L Stainless Steel TIG Welding Rod - 0.035 Inch - 5kg Tube

Premium Grade ER308L Stainless Steel TIG Rods

The Bonarc ER308L TIG Welding Rod is a high-performance stainless steel filler metal designed for the Gas Tungsten Arc Welding (GTAW) process. Engineered to meet the rigorous demands of industrial fabrication, this rod is classified under AWS A5.9 as ER308L. The 'L' designation indicates an extra-low carbon content (maximum 0.03%), which is critical for preventing carbide precipitation during the welding process. This feature significantly enhances the weld metal's resistance to intergranular corrosion, making it suitable for applications where the finished product will be exposed to corrosive environments or high service temperatures up to 350°C (660°F).

This 0.035-inch (0.9mm) diameter rod is particularly well-suited for precision welding on thin-gauge base metals, offering excellent control over the heat input and weld puddle. It is primarily formulated for joining austenitic stainless steels of the 18Cr-8Ni type, such as AISI 304 and 304L. It can also be used for welding stabilized grades like 321 and 347 if the service temperature does not exceed 350°C. The chemical composition is tightly controlled to ensure consistent mechanical properties, including high tensile strength and ductility.

Packaged in a durable 5 kg tube, these rods are protected from moisture and contamination, ensuring they arrive ready for critical code work. The Bonarc ER308L is a staple for industries ranging from food and beverage processing to chemical manufacturing and architectural fabrication, providing a reliable solution for joining common stainless steel grades with confidence.
