62060905V - Bonarc ER308L Stainless Steel MIG Wire .035 5kg Spool

Premium Stainless Steel MIG Welding Wire

The Bonarc ER308L MIG Wire is a high-performance consumable designed for the Gas Metal Arc Welding (GMAW) of austenitic stainless steels. Specifically formulated to meet AWS A5.9 specifications, this wire is classified as ER308L, indicating a composition suitable for welding Type 304 and 304L base metals. The 'L' designation signifies 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 an excellent choice for applications where the finished product will be exposed to corrosive environments or high temperatures.

With a diameter of 0.035 inches (0.9 mm), this wire provides a balance between deposition rate and control, allowing for effective welding on both thin-gauge sheets and medium-thickness plates. The 5kg (approximately 11 lb) spool size is optimized for use with a wide range of wire feeders, including portable suitcase feeders and standard shop bench feeders. The wire is precision-wound to ensure consistent feeding, reducing the risk of tangles or 'bird-nesting' that can interrupt production. Metallurgically, the wire contains approximately 18-20% chromium and 8-10% nickel, ensuring that the weld deposit matches the mechanical and corrosion-resistant properties of the base material.

Industrial applications for the Bonarc ER308L are extensive. It is widely utilized in the fabrication of food processing equipment, dairy tanks, chemical storage vessels, and pharmaceutical apparatuses where sanitary finishes are mandatory. Additionally, it serves well in architectural metalworking and general stainless steel fabrication. For optimal results, this solid wire requires a shielding gas, typically a mixture of Argon and CO2 (98/2) or a helium-rich tri-mix, to achieve a stable spray transfer or short-circuit transfer depending on the welding parameters.
