62181600 - Bonarc ER316LSi Stainless MIG Wire 1.6mm 15kg Spool

High-Performance ER316LSi Stainless Steel MIG Wire

The Bonarc ER316LSi is a premium quality austenitic stainless steel solid wire designed for the Gas Metal Arc Welding (GMAW) of type 316 and 316L stainless steels. This specific alloy formulation includes a higher silicon content ('Hi Sil') than standard 316L wires, which significantly improves the wetting characteristics of the molten weld pool. The result is a smoother bead profile with flatter tie-ins at the toes of the weld, reducing the need for extensive post-weld grinding or finishing.

With a diameter of 1.6mm, this wire is engineered for heavy-duty industrial applications requiring higher deposition rates and deeper penetration on thicker base materials. The 'L' designation indicates a low carbon content (maximum 0.03%), which is critical for preventing carbide precipitation during the welding process. This feature ensures the weld metal maintains high resistance to intergranular corrosion, making it suitable for service environments involving chemical processing, marine conditions, and high-temperature applications.

This 15kg spool is precision-wound to ensure consistent feedability and stable arc characteristics, minimizing downtime caused by wire tangling or feeding issues. It meets AWS A5.9 classifications and is compatible with standard MIG welding equipment set up for stainless steel. The wire typically requires an Argon-rich shielding gas mixture, such as Argon/Oxygen or Argon/CO2, to achieve optimal arc stability and mechanical properties.
