EX316LSI-045M - Exocor ER316LSi .045 Stainless MIG Wire 33lb Spool

High-Performance Stainless Steel MIG Wire for Industrial Fabrication

The Exocor ER316LSi .045" Stainless Steel MIG Welding Wire is a premium filler metal designed for the Gas Metal Arc Welding (GMAW) of austenitic stainless steels. This wire is formulated with a higher silicon content (0.65-1.00%) than standard 316L, which significantly improves the wetting characteristics of the molten weld pool. The result is a smoother bead appearance, better tie-in at the toes of the weld, and increased travel speeds, making it an excellent choice for high-production environments.

Metallurgically, this wire mirrors the composition of type 316L base metals but with the added benefit of enhanced fluidity. It contains Molybdenum (2.0-3.0%), which provides superior resistance to pitting and crevice corrosion, particularly in chloride-containing environments like marine atmospheres or chemical processing plants. The "L" designation indicates an extra-low carbon content (maximum 0.03%), which is critical for preventing carbide precipitation during welding. This ensures the weldment maintains its corrosion resistance without the need for post-weld annealing, preserving the integrity of the joint in harsh service conditions.

Packaged in a 33lb (15kg) spool, this wire is precision layer-wound to ensure consistent feeding and electrical conductivity, reducing liner wear and contact tip burn-back. It is compatible with standard DC+ (DCEP) MIG welding setups and performs optimally with Argon/CO2 blends or Helium-based tri-mix gases. Whether used for structural fabrication, pipe welding, or tank manufacturing, the Exocor ER316LSi delivers reliable, high-quality results that meet stringent AWS A5.9 specifications.
