62070900 - Bonarc ER308LSi .035 Stainless MIG Wire - 15kg Spool

Superior Wetting and Bead Profile

Elevate your stainless steel welding applications with the Bonarc ER308LSi HiSil .035" MIG Wire. This consumable is engineered to meet the rigorous demands of professional welders who refuse to compromise on bead aesthetics or metallurgical integrity. The ER308LSi classification indicates a modification to the standard 308L analysis, featuring a higher silicon content (typically 0.65-1.00%). This metallurgical adjustment significantly enhances the wetting characteristics of the molten pool, promoting a smooth wash-in at the weld edges and a flatter overall profile.

The "L" in 308LSi stands for Low Carbon, a critical factor when welding austenitic stainless steels. By maintaining a maximum carbon content of 0.03%, this wire minimizes the risk of carbide precipitation during the welding process. This ensures that the weldment retains its corrosion resistance, particularly against intergranular corrosion, which is vital for equipment used in chemical processing, food service, and dairy industries. It is perfectly suited for joining base metals like ASTM 304 and 304L, as well as stabilized grades like 321 and 347 (for service temperatures below 400°C).

This 15kg (33lb) spool is optimized for high-volume production. The wire surface is clean and free of contaminants, ensuring stable electrical conductivity and a crisp arc. Compatible with standard MIG welding setups using Argon/CO2 or Tri-Mix shielding gases, the Bonarc ER308LSi delivers spatter-free performance and excellent crack resistance. Choose this wire for applications requiring both structural strength and a high-quality cosmetic finish.
