When you are tackling heavy stainless steel projects, you need a wire that lays down smooth and fast. The Bonarc 316LSi 1.6mm MIG wire is built exactly for that purpose. The 'Si' stands for High Silicon, and for the welder under the hood, that translates to excellent fluidity. The puddle wets out beautifully to the edges, giving you a flat, professional-looking bead that requires far less grinding and polishing than standard 316L wire. It’s a huge time-saver when aesthetics and finish quality matter.
This 1.6mm (0.063") wire is a heavy hitter, designed for welding thicker plates and structural stainless components where smaller diameter wires just can't keep up with the required deposition rates. Whether you are fabricating large chemical tanks, heavy piping systems, or marine equipment, this wire delivers the penetration and fill speed you need to stay productive. The 15kg spool size is perfect for shop environments, reducing the frequency of spool changes during long production runs.
Bonarc has manufactured this wire to feed reliably through your gun, reducing bird-nesting and liner drag. It works best with DCEP polarity and Argon-based shielding gas mixes. If you are welding 316 or 316L grades and want a wire that combines the corrosion resistance of molybdenum-bearing stainless with the smooth handling of a high-silicon alloy, this is the spool to load into your feeder.
