Description
Harris ER309LSi Stainless Steel MIG Welding Wire
Harris ER309LSi stainless steel MIG welding wire is designed for GMAW / MIG welding of stainless steels with similar composition in wrought or cast form. It is also used for welding Type 304 and similar base metals where severe service conditions may exist and may be used for selected dissimilar-steel welding applications. The higher silicon content improves the wetting and washing behavior of the weld metal.
Select the required wire diameter and spool configuration from the product options above. Each available variation is tied to the corresponding Harris item number, package weight, selling price and cost.

Why Choose ER309LSi MIG Welding Wire?
Improved Wetting & Washing
The higher silicon content of ER309LSi improves the wetting and washing behavior of the weld metal, helping produce smooth, consistent weld beads.
Dissimilar-Steel Capability
ER309LSi may also be used for selected dissimilar-steel welding applications. Confirm filler-metal selection with the applicable welding procedure, engineering specification and materials being joined.
Product Selection Considerations
Wire Diameter
Select the MIG wire diameter appropriate for the base-metal thickness, joint design, welding procedure, equipment setup and required deposition rate.
Spool Configuration
Spool availability varies by wire diameter. Select the diameter and spool configuration required for the application and verify compatibility with the applicable welding procedure.
