100996 - ER308LSi .035 Stainless MIG Wire - 33lb Spool

High-Performance Stainless Steel Welding Wire for Industrial Fabrication

The ER308LSi .035" Stainless Steel MIG Wire on a 33lb spool is a premium consumable designed for high-volume industrial welding of austenitic stainless steels. Manufactured to meet rigorous AWS A5.9 specifications, this wire is the preferred choice for professional fabricators working with ASTM 304 and 304L base metals. The "LSi" classification denotes a modification to the standard 308L chemistry, incorporating a higher silicon content (typically 0.65-1.00%) alongside the low carbon formulation. This precise chemical balance delivers superior arc stability and weld puddle fluidity, essential for automated and high-speed manual welding operations.

In industrial environments, efficiency and weld quality are paramount. The increased silicon in this wire improves the "wetting" action of the molten pool, allowing the metal to flow more smoothly into the toes of the weld. This results in a flatter bead profile with exceptionally smooth tie-ins, significantly reducing the labor hours required for post-weld grinding and polishing. Furthermore, the low carbon content (maximum 0.03%) minimizes the risk of carbide precipitation, ensuring the weld zone maintains high resistance to intergranular corrosion—a critical factor for tanks, piping, and structural components in chemical and food processing industries.

Packaged on a durable 33lb (15kg) spool, this wire is optimized for stationary shop welders and industrial wire feeders, reducing downtime associated with frequent spool changes. The precision layer winding ensures consistent wire feeding without tangles or snags, promoting a stable arc and reducing contact tip wear. Whether utilized in spray transfer or short-circuit transfer modes, the ER308LSi wire provides reliable, defect-free welds with excellent cosmetic appearance and mechanical integrity. It is compatible with standard shielding gas mixtures, including Argon/CO2 and Helium-based Tri-mixes, offering versatility across various joint configurations and material thicknesses. For facilities demanding consistent metallurgical properties and high productivity, this Central Wire product delivers proven performance.
