(Typical analysis %) | 0.90 | 0.38 | 0.35 | 4.10 | 6.00 | 4.80 | 1.80 | 1.40 |
End mill, Slitting saws, extra hard lathe bit, machine tap, circular saw blades, etc. When processing stainless steel and titanium alloy, DF6Co has better efficiency than M2
Cutting tool | End mill, side and face cutter |
Slitting saws blade | Extra hard lathe bit | Screw Tap | H.S.S. Circular Saw Blade |
Workable hardness | 65-66 | 64-66 | 65-67 | 64-66 | 64-66 |
Temperature is 40 lower than tempering temperature, and the specific temperature Is determined by mould design.
Steel temperature is 15-20°C lower than tempering temperature, keep the temperature for 2 hours and then air cooling.
