  • Quick Details

    1: 34CrNiMo6 steel introduction
        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.

    4: 34CrNiMo6 steel mechanical properties  

      The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

    6: Heat Treatment
    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.

        Hot forming temperature: 1100-900oC.
        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.
        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.

    7: Delivery condition
        For hot forged bar, usually the delivery condition is hot forged, annealed/QT rough turned/Black surface.
        For hot rolled bar, usually the delivery condition is hot rolled, annealed/QT, Black surface.
        For hot forged plate, usually the delivery condition is hot forged, annealed/QT, milled surface
        For hot rolled plate, usually the delivery condition is hot rolled, annealed/QT, black surface.
