    Microalloyed Steel Hydraulic Cylinder Piston Rod Yield Strength Not Less Than 520 Mpa


    Microalloyed Steel Hydraulic Cylinder Piston Rod Yield Strength Not Less Than 520 Mpa


    Product Description


    1. Shortened processing periods, enhance productivity and reduce the occupied capital.
    2. Low processing cost, needless quenched and tempered process and the second turning.
    3. The steel directly directly turning saves the logistics cost

    4. Save manufacturing expenses and avoid waste in the tempering process
    5. Energy conservation: Production no quenched and tempered process greatly saves the energy
    consumption.
    6. Environments protection: Production no quenched and tempered process meets the requirements of
    environmental protection.
