High Speed Steel With Strong Ductility
|(Typical analysis %)
- On the basis of DF6(M2), EAST TOOL developed DF6M, a high speed steel with strong ductility, which improves
the ability to resist tipping and rupture.
- DF6M controls the chemical composition, especially the carbon content and its carbide particle is even and fine.
For this reason, DF6M has strong ductility and excellent thermoplasticity.
- Adding small amount of cobalt in DF6M improve the ability to resist to hot crackability when over loading.
- Through Electro Slag Remelting (ESR) the composition of DF6M is purified and improved to resist crack and
Be used for tools and dies to resist tipping and stand wear & tear better then M2
Steel density 8.16g/cm3
General Method of heat treatment
Temperature is 40°C 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.
