KDAMAX


JIS :  SKD61 IMP

DAIDO : DH31S

ASSAB : 8407 SUP

HEAT CHECK RESISTANCE

  • The crack length of KDAMAX is 40% shorter than that of SKD61.

    • The KDAMAX slows the expansion of the width of the cracks on the surface of the dies.
    • Occurrence of heat check on the surface of the KDAMAX (47HRC)
    • Relationship between the heat check initiation life and the temperature

    Test conditions

    • High-frequency heating from 100􀋆 to 600􀋆 (with a temperature difference of 500􀋆􀀁between cooling and heating)

    RESISTANCE TO CRACKS FROM ROUNDED CORNERS

    • The crack length of KDAMAX is 40% shorter than that of SKD61.
    • The KDAMAX slows the progress of cracks from the die surface to the water hole.
    • Relationship between the corner shape and Crack initiation life (times)

    RESISTANCE TO EMBRITTLEMENT IN WATER

    • The KDAMAX is more resistant to rust in water than the SDK61 or improved steel.


    Test conditions

    • Water temperature 30􀋆 Immersion time: 50 hours

    RESISTANCE TO FATIGUE LIFE

    • With the KDAMAX, the die is 1.3 to 10 times as resistant to cracks by aging at the water cooling holes as it is with the SDK61 or improved.
    • Result of rotary bending fatigue test (hydrogen embrittled material: 43 HRC)
    • Rotary bending fatigue test (hydrogen embrittled material) Result of rotary bending fatigue test (hydrogen embrittled 􀕳􀰸􀛂􀍛􀵼􀿑

    RESISTANCE TO DISSOLUTION LOSS

    • The KDAMAX is 50% more resistant to dissolution loss than the SKD61.

    Test conditions

    • Molten metal: ADC12
    • Temperature: 700􀋆
    • Retention time: One hour
    • Test sample: 50HRC
