62070800 - Bonarc ER308LSi HiSil Stainless Steel MIG Wire 0.030 15kg Spool

Premium Stainless Steel MIG Wire for Industrial Fabrication

The Bonarc ER308LSi HiSil MIG Wire is a high-quality austenitic stainless steel solid wire designed specifically for the welding of 18% Chromium - 8% Nickel stainless steels. This product carries the AWS classification ER308LSi, where the "Si" denotes a higher silicon content than standard 308L wires. This elevated silicon level improves the fluidity of the molten weld pool, resulting in exceptional wetting properties. Consequently, welders can achieve a flatter bead profile with smoother tie-ins at the toes of the weld, significantly reducing the labor required for post-weld cleaning and grinding.

Engineered for precision and consistency, this 0.030-inch diameter wire is precision-wound on a 15kg spool, ensuring tangle-free feeding during high-volume operations. The "L" in the classification indicates a low carbon content (maximum 0.03%), which is critical for preventing carbide precipitation and maintaining resistance to intergranular corrosion. This makes the wire suitable for applications where the finished product will be exposed to corrosive environments or high temperatures.

This wire is primarily used to join AISI types 301, 302, and 304 stainless steels. It is an excellent choice for fabricating food processing equipment, chemical storage tanks, architectural structures, and general stainless steel manufacturing. The wire performs best with Argon-based shielding gas mixtures, such as Argon/Oxygen or Argon/CO2, providing a stable arc with minimal spatter. Trust Bonarc ER308LSi for reliable, high-strength, and corrosion-resistant welds in your critical stainless steel projects.
