    Tool Steel Cold Finished Bar AISI H12 High Toughness For Extrusion Industry


    AISI H12 / DIN EN X35CrWMoV5 1.2605/1.2606 Tool Steel Bar / Rod 20-1000 mm


    INTRODUCTION


    For hot works tool steels application, we could supply some common tool steels, like H10 steel, H11 steel and H13 steel, and we could also supply AISI H12 tool steel materials for your hot works applications.


    AISI h12 tool steel is a 4.75~5.5% chromium, general-purpose hot work steel. H12 tool steel contains (0.2~0.5%) less vanadium than the widely-used H13 hot works tool steel (0.8~1.2%). ASTM/AISI H12 Steel is a deep-hardening, air-hardening steel that exhibits minimal size change during heat treatmnet. H12 tool steel material has good resistance to thermal fatique cracking (heat cracking) and excellent resistnce to gross cracking and thermal shock when water cooled in service. So, we could say H-12 tool steel mainly has the following characteristics:

    • Excellent resistance to wear, high strength at elevated temperature.
    • Good homogenizing with high toughness.
    • Extra- fine- structure without grain-boundary carbide.
    • Inclusion shape controlled with high cleanliness.

    APPLICATIONS


    AISI H12 hot work tool steel is usually used for hot tooling applications where maximum resistance to cracking is required. Such typical applications include the following:

    • Extrusion indushry: dies and inner liner for extrusion, extrusion tools
    • Forging Industry: forming dies, press dies
    • Die casting industry: dies for die-carbide
    • Tool Industry: hot punch, hot shear blades, immediate roller for cold rolling

    PROCESSING


    Forging of AISI H12 Tool Steel


    Hot forming temperature: 1100-850oC.


    AISI H12 Tool Steel Heat Treatment


    Annealing

    Heating Steel H-12 slowly and uniformly to 845~900℃, furnace cooling to 540℃ at a rate 10~20℃/hr. Hardness HB 229 max


    Stress Relieving

    Stress relieving to remove machining stresses should be carried out by heating H12 steel to approx.650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.


    Hardening

    • Preheating (1): Heat H-12 steel to approx. 540~650℃, holding 30 minutes per 25mm.
    • Preheating (2): Heat H12 tool steels to approx. 845~870℃, holding 30 minutes per 25mm.
    • Austenitizing: Heat steel H12 to approx. 1010~1050℃, holding 30 minutes per 25 mm.
    • Quenchant: By oil or air.

    Tempering

    Tempering temperature: 520-700oC, hold at least 2 hours, air cooling and double tempering.
