  • Quick Details

    1: AISI H13 steel introduction

        H13 Tool Steel is chromium hot work tool steels which are widely used in hot and cold work tooling applications. AISI H-13 tool steel is characterized by good resistance to abrasion at both low and high temperatures, high level of toughness and ductility, uniform and high level of machinability and polishability, good high-temperature strength and resistance to thermal fatigue, excellent through-hardening properties, very limited distortion during hardening.

        In steel H13, the molybdenum and vanadium act as strengthening agents. The chromium content assists die steel H-13 to resist softening when used at high temperatures. H-13 die steels offers an excellent combination of shock and abrasion resistance, and possesses good red hardness. It is capable of withstanding rapid cooling and resists premature heat checking. Tool Steel H13 has good machinability, good weldability, good ductility, and can be formed by conventional means.

    4: AISI H13 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
    Annealing
        Heat slowly to 1550°-1650°F, hold until entire mass is heated through, and cool slowly in the furnace (40F per hour) to about 1000°F, after which cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization.
    Stress Relieving
        When desirable to relieve the strains of machining, heat slowly to 1050°-1250°F, allow to equalize, and then cool in still air (Strain Relieving). Â
    Preheat Prior to Hardening
        Warm slightly before charging into the preheat furnace, which should be operating at 1400°-1500°F.
    Hardening
        H13 tool steel is a steel having very high hardenability and should be hardened by cooling in still air. The use of a salt bath or controlled atmosphere furnace is desirable to minimize decarburization, and if not available, pack hardening in spent pitch coke is suggested. The temperature employed is usually 1800°-1850°F, depending on size section.
    Quenching
        Quench in still air or dry air blast. If complicated forms are to be hardened, an interrupted oil quench can be used. Quench part in oil and remove from bath when it just loses its color (1000°-1100°F). Finish cooling to below 150°-125°F in air, then temper immediately.
    Tempering
        Tempering practice may vary with size and application, but is usually performed in the range of maximum secondary hardness or higher. Double tempering is recommended. The results below is H13 that was air quenched from 1800°F and tempered for 4 hours at various temperatures. The results may be used as a guide, keeping in mind that parts of heavy section or mass may be several points lower in hardness.


    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.
