EDM23447735 - Murex ER316LSi .045 Stainless MIG Wire 25lb Spool

Premium Murex Stainless Steel Welding Wire

The Murex 316LSi .045" MIG Wire is a top-tier consumable designed for professional fabricators who demand excellence in their stainless steel welding applications. As an OEM product from Murex, a brand synonymous with welding heritage and quality, this wire is engineered to deliver consistent results in demanding environments. The "LSi" designation indicates a specific chemical composition that sets this wire apart from standard 316L options. The "L" stands for Low Carbon, which is critical for maintaining corrosion resistance after welding, while the "Si" denotes a higher Silicon content. This unique blend ensures that the molten weld pool flows more freely, wetting out at the toes of the weld to create a smooth, flat bead that requires minimal post-weld grinding or finishing.

Packaged in a substantial 25lb spool, this product is tailored for industrial setups where downtime for spool changes needs to be minimized. The wire is precision-wound, a feature that cannot be overstated in importance; it ensures that the wire feeds smoothly through the liner and contact tip without snagging or tangling, which is a common cause of arc instability and burn-backs. Whether you are fabricating large chemical storage tanks, pharmaceutical equipment, or architectural stainless steel structures, the reliability of Murex wire helps maintain production schedules and weld quality standards.

This wire is specifically formulated to weld molybdenum-bearing austenitic stainless steels, such as type 316 and 316L. The addition of molybdenum provides exceptional resistance to pitting and crevice corrosion, particularly in chloride-rich environments like marine applications or chemical processing plants. By choosing Murex 316LSi, you are investing in a consumable that not only joins metal but enhances the longevity and durability of the final assembly. It is an ideal choice for shops looking to upgrade their stainless steel welding capabilities with a wire that offers both mechanical strength and aesthetic superiority.
