    H13 Tool Steel is chromium hot work tool steels which are widely used in hot and cold work tooling applications. H13 tool steel is classified as group H steels by the AISI classification system. This series of steels start from H1 to H19.

    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.

      Due to H13
      tool steel excellent combination of high toughness and fatigue
      resistance, AISI H13 hot work tool steel is used more than any other
      tool steel in tooling applications.

      4.Forging of H13 Tool Steel
      Heating for forging must be done slowly and uniformly. Soak through at
      1900°-2000°F and reheat as often as necessary, stopping work when the
      temperature drops below 1650°F. After forging, cool slowly in lime,
      mica, dry ashes or furnace. H-13 should always be annealed after
      forging.

      5.Heat Treatment for H13 Tool Steels

        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).

            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.

  • H11 Resource Metal http://www.techsteel.web/alloy/tool-metal/h11

    H-eleven tool metal is a five% chromium incredibly hot get the job done metal that is characterized by superb impact toughness

    It includes fewer vanadium than the commonly-used H13 tool metal furnishing for the better toughness, with some reduction in use resistance and mood resistance.
    H11 tool metal is a deep-hardening, air-hardening metal that reveals small dimensions improve during warmth procedure.
    As a consequence, H11 tool metal is commonly used in the aerospace marketplace.

    H11 tool metal is proposed for incredibly hot tooling purposes exactly where greatest resistance to cracking is necessary this kind of as:

    ● Plane landing equipment
    ● Hot punches
    ● Die casting dies
    ● Forging dies
    ● Hot shear blades
    ● Hot gripper dies
    ● Extrusion tooling

    H11 tool metal is produced to four AMS specs:
