Quick Details

1: AISI D6 steel introduction
    AISI D6 tool steel is a high-carbon, 12% chromium alloy cold work tool steel with tungsten. D6 steel is an air hardening alloy tool steel with excellent resistance to wear and abrasion. As a high carbon high chromium tool steel D6 has better through hardening properties than D3 steel and dimensional stability combined with high resistance to tempering.

4: AISI D6 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 to 700°C and then more rapidly to 900-1050°C.  After forging cool slowly, preferably in a furnace.
Annealing
    As this grade is supplied in the annealed and machineable condition re-annealing will only be necessary if it has been forged or hardened. Anneal the steel at 800-840°C  and slow furnace cool. Hardness after annealing will be approximately 225HB.
Stress Relieving
    When machining operations have been heavy or if the tool has an unbalanced section, remove stresses before hardening by heating up to 650-700°C, equalise, cool slowly.
Hardening
    Pre heat slowly to 750-800°C and soak thoroughly. Continue heating up to the final hardening temperature of 950-980°C, allow the component to be heated through. Cool in air or quench in oil. X210CrW12 is suitable for vacuum (high speed gas) hardening.
Tempering
    Heat the steel uniformly and thoroughly at the selected tempering temperature and hold for at least one hour per 25mm of total thickness. Double tempering of X210CrW12 should be carried out with intermediate cooling to room temperature.

Temperature [°C]	100	200	300	400	500	600
Hardness [HRc]	63	62	60	58	56	48

Heat Treatment
    Heat treatment temperatures, rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, the quenching medium and work piece transfer facilities. Please consult a heat treatment specialist for full guidance on heat treatment.

 

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.
