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. 

  1. Applicable with the maximum hardness 62HRC
  2. Fine microstructure contributes to high toughness and fatigue strength
  3. Greater hardenahility results in high performance even in large dies and gas quenching in vacuum furnace. 
  4. Double melting realizes clean and homogeneous steel with less non-metallic inclusions

Applications

  • Warm forging dies and punches 
  • Cold forging dies and punches
