Product Description
1. The directly turning non-quenched and tempered steel products are used for manufacturing injection
molding machine draglink, engineering machinery push rod and hydraulic prop with the feature that
hardened and tempered steel mechanical property needless quenched and tempered process.
2. Hardness: Hardness is more uniform on the whole cross section than quenched and tempered
42CrMo4, 40Cr and CK45
3. Turning performance: Turning performance is commensurate to 42CrMo4, 40Cr and CK45 or be
superior to them.
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
