    BS EN 42crmo4 Alloy Steel

    is a common chromium-molybdenum steel that usually used after quenched
    and tempered, with high intensity, high hardenability. BS EN 42CrMo4
    round steel has better performance than 34CrMo4 steel due to the carbon
    and chromium content is higher. 42CrMo4 alloy steel

    has higher strength and hardenability. The 42CrMo4 alloy material also
    has high fatigue strength and good low-temperature impact toughness. The

    temper brittleness is not obvious.

    Although 42CrMo4 steel is more expensive than 41Cr4 steel, it is more

    preferable in terms of material properties. EN 42CrMo4 alloy
    engineering steel materials have been widely used in automotive driving
    elements. Otai Steel is able to supply you prime quality of 42CrMo4
    alloy steel materials with wide range.

    5. Heat Treatment of 42CrMo4 Steels

    Annealing of 42CrMo4 Steels

    • Heat steel 42CrMo4 forged steel slowly and thoroughly to 800-850°C;

    • Cool slowly in the furnace to the temperature 480°;

    • Complete annealing the steel in the air.

    Quenched and Tempered (Q+T)

    • Heat 42CrMo4 steel slowly to 880°C;

    • Soak at this temperature then quench in oil;

    • Temper as soon as 42CrMo4 steel reach room temperature (20°C);

    • Heat uniformly to the suitable temperature of 560°C;

    • Withdraw the 42CrMo4 material from the furnace and cool in the air.

    6. Forging of 42CrMo4 Alloy Steel

    • Preheat 42CrMo4 engineering steel uniformly and slowly;

    • Increase the forging temperature up to 1150-1200°C.

    • Always keep the forging temperature above at least 850°C

    7.Weldability

    Engineering

    steel 42CrMo4 has only limited weldability. Preheating to 200-300°C is
    strongly recommended; the upper limit should not be exceeded because of
    risk for deterioration of the chrome layer.

    Alloy steel 42CrMo4
    can be friction welded. However, precautions are necessary so as to
    limit the formation of undesirable microstructures in the welded zone.

    8.Application of 42CrMo4 Alloy Steels

    EN

    42CrMo4 alloy steel is widely used for engineering steel purpose, such
    as: making various kinds of machinery, automobile, mining spare part,
    the gearwheel of the engine, the driving gear of supercharger, the
    connecting rob, the pinchock under the high pressure, parts for power
    train applications, cold formed fastener components, shafts, gears,
    drill collars for the oil exploration, etc.
