ISO Micro Alloy Steel Hard Chrome Plated Rod Directly Turning
 
 
Product Description
1. The mechanical property of non-quenched and tempered steel products is correspond to quenched
    and tempered 42CrMo4, 40Cr and CK45 or over them and very uniform on the whole cross section.
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. Save manufacturing expenses and avoid waste in the tempering process.
5. Shortened processing periods, enhance productivity and reduce the occupied capital.
6. Low processing cost, needless quenched and tempered process and the second turning.
