    EN 34CrNiMo6 Steel

    is an important alloy engineering steel grade as per BS EN
    10083-3:2006. 34CrNim06 steel has high strength, high toughness and good

    hardenability. EN / DIN 34CrNiMo6 alloy steel has the stability of
    resistance to overheating, but the white sensitivity of 34CrNiM06 is
    high. It also has the temper brittleness, so the weldability of
    34CrNiMo6 material is poor. The steel 34CrNiMo6 needs the high
    temperature preheating before welding in order to eliminate the stress
    after welding processing.

    5.Heat Treatment of 34CrNiMo6 Engineering Steel

    Quenched and Tempered (Q+T) of 34CrNiMo6 Steel

    • Heat 34CrNiMo6 round steel slowly to the temperature of 850°C;

    • Soak at this hardening temperature quench in oil;

    • Temper as soon as 34CrNiMo6 steels reach room temperature.

    • Heat uniformly to the suitable temperature;

    • Withdraw from the furnace and cool in the air.

    • The usual tempering temperature is 600°C which depending on the actual requirements.

    6.Forging of DIN 34CrNiMo6 / 1.6582 Steel

    Hot forming temperature: 1100-900oC.

    7.Machinability of Steel 34CrNiMo6

    Machining

    is best done with this 1.6582 alloy steel in the annealed or normalized

    and tempered condition. It can be machined by all conventional methods.

    8.Welding

    The

    alloy materials can be fusion or resistance welded. Preheat and post
    heat weld procedures should be followed when welding this alloy by
    established methods.

    9.Application

    EN DIN
    34CrNiMo6 steel is used to make tools which demands good plasticity and
    high strength. It is usually selected to make the big size and important

    parts, such as heavy machinery axle,turbine shaft blade, high load of
    transmission parts, fasteners, crank shafts, gears, as well as heavily
    loaded parts for motor construction etc.
