Selectarc FCW 309LMO

This high productivity cored wire, designated FCW 309LMO, is a rutile flux cored wire specifically formulated for gas shielded arc welding of stainless steel 309L alloys enriched with Molybdenum. It’s designed for heterogeneous assembly with both stainless steel and low alloy steels, suitable for applications up to a service temperature of +350°C. The wire is particularly well-suited for downhand and horizontal welding positions. The flux provides excellent weld quality and penetration. Consult the Material Safety Data Sheet (MSDS) for detailed fume information.

This cored wire is ideal for welding stainless steel 309L in applications like welding similar composition stainless steels, serving as a buffer layer, and rebuilding before hardfacing operations. It’s commonly used in positions where downhand and horizontal welding are required. The specified welding parameters (shielding gas, current, voltage, and stick out) are suitable for FCAW (Flux Cored Arc Welding) with an Ar + CO2 or 100% CO2 shielding gas.
