Diameter 35 - 140 Mm Micro Alloy Steel Thread Rod Chrome Plating
 

 
Product Description
1. Micro struction: Ferrite and pearlite with fine and uniform grain size.
2. Turning performance: Turning performance is commensurate to 42CrMo4, 40Cr and CK45 or be
    superior to them.
3. Hardness: Hardness is more uniform on the whole cross section than quenched and tempered
    42CrMo4, 40Cr and CK45
4. Shortened processing periods, enhance productivity and reduce the occupied capital.
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.
