35EA12982V - E309LMoT1-1 Stainless Flux Core Wire .045 33lb Spool

Industrial Grade Stainless Steel Flux-Core Wire

The E309LMoT1-1 Stainless Steel Flux-Core Wire is a premium consumable designed for demanding industrial fabrication and maintenance operations. Engineered with a specific alloy composition that includes Molybdenum, this wire provides enhanced corrosion resistance compared to standard 309L wires. It is the go-to solution for maintenance departments and fabrication shops tasked with joining dissimilar metals, specifically when welding Type 316 stainless steel to mild or low-alloy carbon steels.

Packaged in a substantial 15kg (33lb) spool, this .045" diameter wire ensures long run times and reduced downtime for spool changes, making it highly efficient for continuous production environments. The flux-cored design allows for higher deposition rates than solid wires and supports all-position welding, giving operators the flexibility to tackle complex structural repairs or fabrication projects without constantly repositioning the workpiece.

Reliability is key in industrial MRO, and this wire delivers a stable arc with minimal spatter, ensuring high-quality weld deposits that pass rigorous inspections. Whether used for overlay cladding to restore worn parts or for structural joining in petrochemical and power generation facilities, this 309LMo wire offers the mechanical strength and chemical resistance required for critical applications.

Primary Industrial Use Cases

• Dissimilar Metal Joining: Expertly bonds stainless steel to carbon steel.


• Corrosion Resistant Cladding: Ideal for the first layer of overlay on carbon steel.


• Heavy Fabrication: Suitable for tanks, vessels, and structural supports.
