ED035602 - Murex 308LSi Stainless Steel MIG Wire - 1/16 Inch Diameter

Industrial-Grade Murex 308LSi Stainless MIG Wire

The Murex 308LSi Stainless MIG Wire (SKU: ED035602) is a premium consumable designed for high-performance gas metal arc welding (GMAW) of austenitic stainless steels. Engineered with a 1/16-inch (1.6mm) diameter, this wire is specifically optimized for applications requiring higher deposition rates and penetration on thicker base materials. The "Si" designation indicates a higher silicon content (typically 0.65-1.00%) compared to standard 308L wires. This metallurgical adjustment significantly lowers the surface tension of the molten weld pool, enhancing wetting action and allowing the puddle to flow out smoothly towards the toes of the weld. This results in a flatter bead profile and reduced grinding time post-weld.

Metallurgically, the wire maintains a low carbon content (0.03% maximum), which is critical for preventing carbide precipitation at the grain boundaries during the welding thermal cycle. This feature preserves the corrosion resistance of the base metal, making it an ideal choice for welding ASTM 304 and 304L stainless steels in industrial environments. The Murex manufacturing process ensures consistent wire feeding, stable arc characteristics, and minimal spatter, reducing downtime and cleanup costs in production settings.

Technical Application

This wire is suitable for welding 18Cr-8Ni steels and is widely used in the fabrication of chemical processing equipment, food service machinery, and architectural structures where both structural integrity and aesthetic finish are paramount. The 1/16" diameter requires appropriate power source capability to sustain the spray transfer mode effectively, ensuring deep fusion and structural soundness.
