    Detailed Product Description
    Shape: Sheet/Round Bar Type: Alloy Steel
    Surface Treatment: Black Temperings: 530-560℃
    Casting Type: Static Ingot Technology: Hot Rolled

    AISI 4140 steel is the stand of the USA. And the GB 42CrMo steel has the same properties and chemical composition for 4140 steel in China. But at the part of extensibility is lower than 4140. But the gap is not big. It is high has high strength and toughness. And the hardening capacity also is good. After the processing of hardening and tempering, the shock resistance capability and fatigue value will be getting better.

    4140 Steel Chemical composition:

    Carbon: 0.38%-0.43%
    Silicon: 0.15%-0.35%
    Manganese: 0.75%-1.00%
    Sulfur: ≤0.040%
    Phosphorus: ≤0.030%
    Chromium: 0.80%-1.10%
    Nickel: ≤0.030%
    Copper: ≤0.030%
    Molybdenum: 0.15%-0.25%

    Mechanical Property:
    Intensity of tension: ≥110MPa
    Yield Strength: ≥95MPa
    Hardness: ≤217HB

    4140 Steel Application:

    After the heat treatment, its total properties will be improved. Such as strength and mechanical properties. Its technological properties are good, the lumber recovery also at a high level. The highest temperature of use is 427℃. It is used to make the forgeable piece with high strength and big section of quenching and tempering.
