35mm - 140mm Micro Alloyed Steel Rod Tensile Strength Not Less Than 750mpa
 

 
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.
