    In ASTM A681 standard, L6 steel grade is in L-type for special purpose tool steels. AISI L6 tool steel
    is in the general class of alloy, oil-hardening tool steel that is
    characterized by good toughness. ASTM L6 tool steel is suitable for use
    as tools, dies, and machine parts, which require a good combination of
    hardness and toughness.

    Due to its lower carbon content and
    relatively high nickel content, L6 tool steel has slightly better
    shock-resistance than more highly alloyed types and should be used where
    some wear-resistance can be sacrificed for increased toughness.

    • Thermal conductivity [W/m.K]: 36.0

    • Electric resistivity [Ohm mm2/m]: 0.30

    • Specific heat capacity[J/g.K]: 0.46

    Mechanical Properties of L6 Steels

    Properties Metric Imperial
    Poisson’s ratio 0.27- 0.30 0.27- 0.30
    Elastic modulus 190-210 GPa 27557-30457 ksi

    4. Forging of L6 Tool Steel

    Forge at 1079°C (1975 F) down to 871°C (1600 F). Do not forge below 843°C (1550 F).

    5. AISI L6 Tool Steel Heat Treatment

    Hardening

    Preheating:
    Heat steel L6 at a rate not exceeding 204°C (400°F) per hour (222°C per
    hour) to 621-677°C (1150-1250°F) and equalize. Soak for 30 minutes for
    the first inch (25.4 mm) of thickness, plus 15 minutes for each
    additional inch (25.4 mm).

    Quenching

    Quench L6 tool steel in oil to 66-51°C (150-125°F).

    Tempering

    Temper
    L6 steels immediately after quenching. Hold at temperature for 1 hour
    per inch (25.4 mm) of thickness when tempering at 204°C (400°F), 4 hours
    minimum, then air cool to ambient temperature.
    However, where increased toughness is desired, at a sacrifice of some hardness, higher tempering temperatures are often used.

    AISI L6 steel does not become brittle, as many other die steels do, when tempered in the range of 232°C to 426°C (450 to 800°F).

    To
    minimize the possibility of cracking, the steel should be tempered
    immediately after hardening and should be heated slowly to the desired
    tempering temperature.

    Annealing

    Annealing of steel L6 must be performed after hot working and before re-hardening.

    Heat
    to 760°C (1400°F) and hold one hour per inch of maximum thickness. Then
    cool slowly with the furnace at a rate not exceeding 28°C per hour(50°F
    per hour) to 538°C (1000°F). Continue cooling to ambient temperature in
    the furnace or in air.

    For improved machinability, hold at 760°C
    (1400°F) for 1 hour per inch (25.4mm) of maximum thickness; 2 hours
    minimum. Then cool slowly with the furnace cool from 677°C (1250°F) to
    760°C (1400°F), hold for 8 hours, then air cool to ambient temperature.

    Because of its air-hardening ability, steel L6 should not be normalized.

    6. Machinability of Steel L6

    Machinability
    of tool steel L6 is very good. It rates 90% of the machinability of the
    W-group water hardening low alloy steels rated 100% as a baseline.

    7. Applications of ASTM A681 L6 Tool Steel

    AISI
    L6 cold working tool steel is for general purpose tools and dies where
    greater toughness is required, but with some sacrifice of
    abrasion-resistance.

    Typically used below applications:

    • spindles,

    • forming rolls,

    • punches,

    • blanking and forming dies,
