Selectarc FCW 307M

This metal cored wire, designated FCW 307M, is specifically formulated for the gas shielded (Ar + CO2) arc welding of challenging stainless steels and manganese steels. It is non-magnetic and resists hot cracking and work hardening in the weld deposit. This makes it ideal as a buffer layer before hardfacing grades sensitive to cracking or for dissimilar joints between stainless steel and steel construction. It’s commonly used in civil engineering projects, particularly for road, rail, and fluvial works, as well as in quarry and cement applications.

The FCW 307M wire is particularly well-suited for applications requiring robust welding of difficult-to-weld materials. Its properties make it ideal for situations demanding resistance to cracking and work hardening, such as preparing for hardfacing, joining dissimilar metals, or welding in demanding environments like road construction or quarrying. Welding parameters and shielding gas selection (Ar/CO2) are crucial for optimal results.
