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.

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