101006 - ER316LSi Stainless MIG Wire - 0.035 in - 10 lb Spool

High-Performance 316LSi MIG Welding Wire

Achieve superior weld quality and aesthetic results with the Central Wire ER316LSi Stainless Steel MIG Wire. This 0.035-inch solid wire comes in a convenient 10 lb spool, making it an ideal choice for professional welders tackling medium-sized projects or production runs. The ER316LSi classification represents a premium upgrade over standard 316L wires, specifically formulated to address common challenges in stainless steel welding. The higher silicon content acts as a deoxidizer and improves the surface tension of the molten pool, allowing the weld metal to wet out smoothly against the base material. This results in exceptionally clean, flat welds with smooth transitions, minimizing the labor required for grinding and polishing.

Metallurgically, this wire is designed for joining type 316 and 316L stainless steels, as well as 318 type steels. It offers robust mechanical properties and exceptional corrosion resistance, thanks to the addition of molybdenum. This makes it highly effective in harsh environments where the metal is exposed to organic and inorganic acids, salts, and chlorides. The low carbon content is a critical safety factor, preventing sensitization and ensuring the longevity of the weld zone against intergranular attack.

For optimal performance, this wire should be used with Direct Current Electrode Positive (DCEP) polarity and appropriate shielding gases. While Argon/CO2 blends (such as 98/2) are common, using a Tri-Mix gas can further enhance the arc stability and bead color. Whether you are fabricating custom kitchen equipment, repairing marine hardware, or building industrial heat exchangers, this ER316LSi wire delivers the consistency and quality professional welders demand. The precision winding of the spool ensures smooth feeding through your MIG gun liner, reducing downtime caused by bird-nesting or feed interruptions.

Features & Benefits:

• Enhanced Wetting: High silicon content ensures flat, smooth beads.
• Corrosion Resistance: Molybdenum and low carbon protect against pitting and decay.
• Versatile Diameter: 0.035" size is perfect for a wide range of material thicknesses.
• Reliable Feeding: Precision-wound 10 lb spool fits most standard wire feeders.
