Daido's Dream Series
DRM2
Warm and Cold Forging Die Steel
High
hard and tough matrix type high speed tool steel
Features
Matrix type high speed tool
steel available for warm and cold forging tools where
critical performance is required. DRM2 prolongs service
life due to its higher hardness and toughness than those of
conventional grades.
- Applicable with the
maximum hardness 62HRC
- Fine microstructure
contributes to high toughness and fatigue strength
- Greater hardenahility
results in high performance even in large dies and gas
quenching in vacuum furnace.
- Double melting realizes
clean and homogeneous steel with less non-metallic
inclusions
Applications
- Warm forging dies and
punches
- Cold forging dies and
punches
