FOXcore 307-MC is a high alloyed austenitic stainless metal-cored wire of the EC 307 type for special applications and dissimilar joints, with good resistance to embrittlement down to minus 60 degrees C.
The wire gives a high deposition rate and a wide, flat penetration profile with a stable spray arc, and it runs well on robot and mechanised stations. Its deposit has an austenitic structure that resists corrosion.
Classification EN ISO: 17633-A T 18 8 Mn M M12 1
AWS classification: A5.22 / SFA-5.22 EC307 (mod.)
Shielding gas: M12
Diameters: 1.2 / 1.6 mm
Approvals: TÜV (10871), DB (43.014.27), CE
Use brushes and discs kept only for stainless steel, carbon steel particles cause rust staining on the bead face. Set the parameters for spray arc, in the short arc range a metal-cored wire loses its deposition advantage.

Typical weld metal values from the voestalpine Böhler Welding data sheet, issue 05/2024. The minimum or the range guaranteed by the maker is given in brackets. The figures depend on the heat treatment condition and the shielding gas stated in the row and do not replace testing the joint to your own WPS.

For which materials and machines
Base materials
Material group: stainless and acid-resistant steels. The exact grades and thicknesses are in the manufacturer data sheet, and for an unusual joint call us, we will pick the filler metal.
Process and machines
Flux-cored wire, works on any sound machine for this process: welders. Shielding gas: M12: Ar with CO2 added (up to 5 %).
