    Product Description
    1. Turning performance: Turning performance is commensurate to 42CrMo4, 40Cr and CK45 or be
        superior to them.
    2. Hardness: Hardness is more uniform on the whole cross section than quenched and tempered
        42CrMo4, 40Cr and CK45
    3. Micro struction: Ferrite and pearlite with fine and uniform grain size.
    4. The steel directly directly turning saves the logistics cost
    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.
