FTCo steel:
high temper resistance and wear resistance.

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.

  • High contents of carbide-forming elements.
  • High temper resistance.
  • Good wear resistance.
  • Dies and mandrels for forging applications with very high thermal and abrasive loads.
  • Particularly suitable for mandrels in fast cutting machines.
