    Heat treatment Related

    • Annealing of 65Mn Spring Steel

    At first Slowly heated to 730 ℃ and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. Then 65Mn tool steel will get MAX 250 HB (Brinell hardness).

    • Hardening of 65Mn Spring Steel

    At the beginning, 65Mn steels should be heated uniformly to 830-860°C (1526-1580°F) until completely heated through. After about 30 min per 25 mm of ruling section is to be provided and then the steels should be immediately quenched in oil. Tempering of 65Mn Spring Steel

    Tempering of 65Mn steels is performed at 540°C, Soak well at the selected temperature and soak for at least one hour per 25mm of total thickness. Hardness values at different temperatures after tempering


    Mechanical Properties

    The mechanical properties of 65Mn Spring Steels are outlined in the following table.

    Tensile strengthConditions to yield strengthElongationReduction of areaHardness (Hot Rolled)Hardness (Cold Drawn)
    σb (MPa):≥980σ0.2 (MPa):≥785δ 5 (%):≥8ψ (%):≥30≤302HB;

    Applications

    65Mn steel, after heat treatment and cold drawing hardening, high strength, it has a certain toughness and plasticity; In the same surface hardening case, completely and the fatigue limit and alloy spring. But hardenability poor, mainly for the smaller size of the spring, such as regulating speed regulating spring, spring load, general machinery in the round, square spiral spring or pull wire for small mechanical spring.
