    Product Description


    1. The micro alloy steel products are developed on the basis of proprietary technology of the control

        rolling and cooling for substituting quenched and tempered piston rods with a variety of mechanical

        performance requirements.
    2. The mechanical property is correspond to quenched and tempered piston rods or over them and

        very uniform on the whole cross section.
    3. Hardness is more uniform on the whole cross section than quenched and tempered piston rods

    4. Turning performance is commensurate to quenched and tempered piston rods or be superior to them.
    5. Micro alloy steel rod mainly used in mechanical manufacturing for the directly turning part of shaft
       and rod, ect
    6. The processing period is shortened, and the productivity is enhanced and the occupied capital is
        reduced..
    7. The processing cost is low, there is no need of quenched and tempered process and the second
        turning but the mechanical property is correspond to quenched and tempered piston rod
