    L3 General Information

    L3 tool steel is an oil hardening cold work steel with good hardenability, wear resistance, toughness and good cutting-edge retention as well as good impact resistance. As a medium alloyed cold steel L3 offers a high hardenability, however, its hardening depth is low. It finds its uses in a wide range of industries and applications, like in the wood and paper industry for paper cutters and circular saw blades. As it reliably retains its dimensions it is also well suited for measuring tools, i.e., a caliper. Apart from roller- and ball bearings this steel grade is used for drills, thread taps and treading dies.


    Heat treatment


    Annealing

    To anneal L3 tool steel, heat the parts uniformly to a temperature of 1382-1472°F (750-800°C), following this with a slow cooling of the material in the furnace.


    Normalizing

    Heat the material uniformly to a temperature of 1598-1652°F (870-900°C) and then cool in air.


    Stress relieving

    The work pieces is heated uniformly to a temperature of 1112-1202°F (600-650°C) and hold for 1-2 hours at the temperature. Then cool, to start off with, in the furnace and follow it up with cooling in air.


    Hardening

    Heat the L3 tool steel parts slowly to a temperature range of 1472-1598°F (800-870°C). The holding time for this material is 65 minutes per inch (25.4 mm) of thickness. To avoid loss of hardness, the material has to be transferred quickly from the furnace to the oil.


    Quenching media
    • Water for a temperature of up to 1526°F (830°C) and above that temperature with the following
    • Oil, 356-428°F (180-220°C)
    • Hot bath, 356-428°F (180-220°C)

    Tempering

    Slowly and uniformly heat the L3 material to the chosen tempering temperature and hold for 2 hours.

    Welding

    L3 tool steel grade is not suitable for welding.
