Die Cast & Forging Steels

DH31-EX

Hardenability:

High toughness is obtained even in large size dies due to high hardenability. 

  • Continuous cooling transformation curve

  • Bainite hardenability
    As Bainite transformation starting time is twice as that of SKD61, 130min., quenching operations is easily and safely carried out without troubling such as toughness deterioration in large size dies.

     
  • Quenching cooling time vs. toughness
     

    Cooling time of mid portion from 1030C to 300C (min)
      
  • TP size: 440
     
  • Quenching temp: 1030C
