Steel FTCo
FTCo steel:
high temper resistance and wear resistance.
What?
FTCo is a special tool steel with high contents of carbide-forming elements (Cr, Mo, V, W, Nb), which guarantee particularly high temper resistance and wear resistance.
Material properties
- High contents of carbide-forming elements.
- High temper resistance.
- Good wear resistance.
Application
- Dies and mandrels for forging applications with very high thermal and abrasive loads.
- Particularly suitable for mandrels in fast cutting machines.
