JIS SKT6 DIN 45NiCrMo16 Hot Work Tool Steel Round Bar

1:  JIS SKT6  steel introduction

   SKT6 has the advantages of good abrasion resistance, high toughness, high hardness, high compressive strength and dimensional stability, as well as good corrosion resistance. Polishing and cutting pin performance is also very good, it is easy to achieve the mirror effect.

3:   JIS SKT6  steel chemical composition

4:   JIS SKT6  steel mechanical properties   
  The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

6. Heat Treatment

Forging

     Heat slowly and evenly to 1050 ºC. Reheat the steel if necessary to avoid working at temperatures below 850 °C. After forging the steel, cool slowly in a furnace or in an insulating material.

Annealing

   The components are homogeneously heated 630 - 650 ºC to soak and then slowly cooled in an oven to about 600 °C and cooled in air.

Hardening

   Heat the tool slowly and evenly to 650 - 700 °C and soak thoroughly continue to the hardening temperature of 840 - 870 °C and heat the assembly through. Quench the assembly or cool it in air.

7: Delivery condition
    For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
    For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.

    For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
