Classification

| EN ISO class | S Fe 4 |
Purpose
- Highly alloyed Mo-V-W solid TIG rod (S Fe 4), high-speed-steel type, 57-62 HRC hardness — the highest in the TLS line.
- Repair and new manufacture of cutting tooling: cutting tools, planer blades, lathe tools, broaches.
Why it works
Molybdenum (8.3%) together with vanadium (1.9%) and tungsten (1.8%) on a high-carbon base (1.0%) reproduces high-speed-steel metallurgy — the deposit is only machinable by grinding without prior annealing, the same trait that distinguishes a high-speed steel from a conventional tool steel.
Fields of application
- Cutting tools, planer blades, lathe tools, broaches.
- Repair and new manufacture of demanding cutting tooling.

Advantages
- Highest hardness in the TLS line (57-62 HRC).
- High-speed-steel metallurgy — retains cutting edge at elevated temperature.
Limitations
- The deposit is only machinable by grinding — no conventional machining without prior annealing.
