Product Description
1. Save manufacturing expenses and avoid waste in the tempering process
2. Shortened processing periods, enhance productivity and reduce the occupied capital.
3. The mechanical property is correspond to quenched and tempered 42CrMo4, 40Cr and CK45 or over
them and very uniform on the whole cross section.
4. Turning performance: Turning performance is commensurate to 42CrMo4, 40Cr and CK45 or be
superior to them.
5. Hardness: Hardness is more uniform on the whole cross section than quenched and tempered
42CrMo4, 40Cr and CK45.
6. Mainly used in mechanical manufacturing for the directly turning part of shaft and rod, ect.
