    4340 steel is nickel-chromium-molybdenu m alloy steel.

    High strength is obtained after heat treatment.

    And it has good toughness, fatigue resistance, impact resistance and etc.

    4340 steel properties and 4340 steel composition as follows.

    It is an alloy structural grade used by SAE International (SAE) and is a low alloy chromium-nickel steel.

    4340 steel has high tensile strength, hardness and toughness after heat treatment.

    It is widely used in gear components of heavy chemical machinery.

    Different sections of each part of the casting that cause the temperature difference stress and the phase transformation stress.

    If you don't know their laws and properties, you can't do the right rational processes.

    As a result, there is a risk that the casting will crack during casting or heat treatment.

    Therefore, the control of the chemical composition and the choice of the heat treatment process for the casting are very important.

    Corresponding steel number:

    China GB steel number 40CrNiMoA, German DIN steel number 36CrNiMo4, German DIN material number 1.6511, French NF standard 40NCD3, Japanese JIS standard SNCM439, British BS standard 816M40, American AISI/ASTM4340, American UNS standard G43400
