309L TIG Filler Wire

Product Details

309L TIG Filler Wire

309L TIG Filler Wire is a stainless steel welding rod designed for TIG (GTAW) welding applications. It is commonly used for welding stainless steels and for joining dissimilar metals such as stainless steel to mild steel or low-alloy steels. The low carbon content of the 309L alloy helps reduce carbide precipitation during welding, improving resistance to intergranular corrosion and ensuring clean, durable welds.

This filler wire is widely used in fabrication, maintenance, and industrial repair work where corrosion resistance, strength, and reliable weld performance are required.
