    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). 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.

    Allotropes Of Carbon

    The different forms or allotropes of carbon (see below) include the hardest naturally occurring substance, diamond, and also one of the softest known substances, graphite. Moreover, it has an affinity for bonding with other small atoms, including other carbon atoms, and is capable of forming multiple stable covalent bonds with such atoms. As a result, carbon is known to form almost ten million different compounds; the large majority of all chemical compounds. Carbon also has the highest melting and sublimation point of all elements. At atmospheric pressure it has no melting point as its triple point is at 10.8 ± 0.2 MPa and 4600 ± 300 K, so it sublimates at about 3900 K
    Carbon sublimes in a carbon arc which has a temperature of about 5800 K. Thus, irrespective of its allotropic form, carbon remains solid at higher temperatures than the highest melting point metals such as tungsten or rhenium. Although thermodynamically prone to oxidation, carbon resists oxidation more effectively than elements such as iron and copper that are weaker reducing agents at room temperature.
    Carbon compounds form the basis of all known life on Earth, and the carbon-nitrogen cycle provides some of the energy produced by the Sun and other stars. Although it forms an extraordinary variety of compounds, most forms of carbon are comparatively unreactive under normal conditions. At standard temperature and pressure, it resists all but the strongest oxidizers. It does not react with sulfuric acid, hydrochloric acid, chlorine or any alkalis. At elevated temperatures carbon reacts with oxygen to form carbon oxides, and will reduce such metal oxides as iron oxide to the metal. This exothermic reaction is used in the iron and steel industry to control the carbon content of steel:
    Fe3O4 + 4 C(s) → 3 Fe(s) + 4 CO(g)
    with sulfur to form carbon disulfide and with steam in the coal-gas reaction:
    C(s) + H2O(g) → CO(g) + H2(g).
    Carbon combines with some metals at high temperatures to form metallic carbides, such as the iron carbide cementite in steel, and tungsten carbide, widely used as an abrasive and for making hard tips for cutting tools.
    As of 2009, graphene appears to be the strongest material ever tested. However, the process of separating it from graphite will require some technological development before it is economical enough to be used in industrial processes.
    The system of carbon allotropes spans a range of extremes:
    Synthetic nanocrystalline diamond is the hardest material known.Graphite is one of the softest materials known.
    Diamond is the ultimate abrasive.
    Graphite is a very good lubricant.

    Diamond is an excellent electrical insulator.
    Graphite is a conductor of electricity.

    Diamond is the best known naturally occurring thermal conductor
    Some forms of graphite are used for thermal insulation (i.e. firebreaks and heat shields)

    Diamond is highly transparent.Graphite is opaque.

    Diamond crystallizes in the cubic system.
    Graphite crystallizes in the hexagonal system.

    Amorphous carbon is completely isotropic.
    Carbon nanotubes are among the most anisotropic materials ever produced.
