Purpose
- Metal-cored wire for UNI 430/510 steel and fine-grained equivalents, especially suited to automation (AWS E70T15-M21A8-CS1-H4/E70T1, EN ISO T46 6 M M1 H5/T42 5 M C1 H5).
Why it works
The metal core gives high yield, good operating behavior and no slag or spatter to manage — characteristics that make it particularly suited to automated and robotized machines.
Fields of application
- UNI 430, UNI 510 steel and fine-grained equivalents, automated and robotized welding in all positions.

Advantages
- Especially suited to automation and robotization — stable arc with no slag to manage.
- Weldable in all positions, unlike FERVEO STL BF31 FCW (restricted to flat and horizontal-fillet).
Limitations
- For the same type of steel with basic instead of metal-cored character, see FERVEO STL BF31 FCW.
