Chemical Composition for Steel C25

Sorry, Not Availble for this Material


Cutting Speeds Recomendations for Non-alloyed steel 0.26-0.50% Carbon

Application Vc (m/min) Vc (SFM)
Turning 240-350 790-1150
Milling 150-220 490-720
Parting 115-170 380-560
Grooving 135-195 440-640
Drilling 95-140 310-460

Important! The speed estimation is given for an ideal situation:
  • Most suitable carbide grade
  • Stable tool clamping
  • Stable workpiece clamping
  • Good quality raw material
  • A short overhang of the cutting tool.
  • Nominal hardness of the material.
  • etc.
