Description
Harris ER309L Stainless Steel MIG Welding Wire
Harris ER309L stainless steel MIG welding wire is a low-carbon ER309L filler metal 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 lower carbon content of 0.03% maximum helps reduce the possibility of intergranular carbide precipitation.

Why Choose ER309L MIG Welding Wire?
Low-Carbon Stainless Filler
ER309L contains a maximum of 0.03% carbon, helping reduce the possibility of intergranular carbide precipitation in appropriate stainless steel welding applications.
Dissimilar-Steel Capability
ER309L is also 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.
Package Configuration
Package availability varies by wire diameter. Select the diameter and package combination required for the application and verify compatibility with the applicable welding procedure.
