62180900 - Bonarc ER316LSi Stainless Steel MIG Wire - 0.035 Inch - 15kg Spool

Premium Stainless Steel Welding Wire for Clean Results

The Bonarc ER316LSi MIG Wire is a top-tier choice for fabricators demanding excellence in stainless steel welding. This 15kg spool of 0.035-inch wire is specifically engineered with a high silicon content, which significantly improves the wetting action of the weld metal. For professionals working in industries where aesthetic finish and corrosion resistance are paramount—such as food processing, pharmaceutical manufacturing, and architectural fabrication—this wire delivers superior results.

One of the standout features of this product is its "Low Carbon" (L) designation combined with high silicon (Si). The low carbon content is critical for preventing intergranular corrosion, ensuring that your welds remain durable even in harsh environments. Meanwhile, the added silicon helps the molten pool flow more smoothly, resulting in flatter beads with smoother tie-ins. This reduces the need for extensive post-weld grinding and polishing, saving you valuable time and labor costs on every project.

Designed for use with standard MIG welding equipment, this solid wire feeds smoothly thanks to Bonarc's precision winding and quality manufacturing processes. Whether you are welding tanks, piping systems, or marine hardware, the Bonarc 316LSi provides the consistency and arc stability required for high-quality production welding. The 15kg spool size is ideal for industrial setups, minimizing downtime caused by frequent spool changes.

Key Benefits:

• Superior Finish: High silicon improves bead appearance.


• Corrosion Resistant: Molybdenum content protects against pitting.


• Efficient: Excellent feedability reduces bird-nesting and downtime.
