ED035601 - Murex 308LSi .035 Stainless MIG Wire 33lb Spool

Premium Murex 308LSi Stainless Steel MIG Wire

The Murex ER308LSi .035" MIG Wire in a 33 lb spool is a high-performance stainless steel welding consumable designed for precision and aesthetic quality. Manufactured under the renowned Murex brand, a subsidiary of Lincoln Electric, this wire is engineered to meet the rigorous demands of modern industrial fabrication. The "Si" in the classification denotes a higher silicon content compared to standard 308L wires. This chemical modification is not merely for specification compliance; it serves a critical functional purpose. The increased silicon lowers the surface tension of the molten weld pool, significantly improving fluidity and wetting action. This results in a weld bead that ties in smoothly with the base metal, reducing the need for post-weld grinding and finishing.

This wire is specifically formulated for joining austenitic stainless steels of the 18-8 type, such as AISI 304 and 304L. The "L" designation indicates a low carbon content (maximum 0.03%), which is essential for preventing carbide precipitation during the welding process. By minimizing carbide precipitation, the wire maintains the corrosion resistance of the weldment, particularly against intergranular corrosion, ensuring the longevity and structural integrity of the final product. It is an excellent choice for industries ranging from food and beverage processing equipment to architectural structures where visual appeal is paramount.

Packaged in a substantial 33 lb spool, this product is optimized for high-volume production environments. The precision layer winding ensures consistent feeding through the liner and contact tip, reducing downtime associated with bird-nesting or arc instability. Murex ensures quality control through their Q2 Lot program, providing users with access to actual wire composition certificates and calculated ferrite numbers (FN), ensuring compliance with AWS A5.9 and ASME SFA-5.9 standards.

Whether utilized in automated robotic cells or manual welding stations, the Murex 308LSi provides a stable arc and minimal spatter. It is compatible with a variety of shielding gases, including Argon/CO2 and Argon/Oxygen mixtures, allowing fabricators flexibility based on their specific procedure specifications. This wire represents a convergence of metallurgical science and practical welding performance.
