Introduction of non-quenched and tempered steel products:
The directly turning non-quenched and tempered steel products are developed on the basis of the proprietary technology of the control rolling and cooling for substituting quenched and tempered 42CrMo, 40Cr and ck45 with a variety of mechanical performance requirements. It is mainly used in mechanical manufacturing for the directly turning part of shaft and rod, etc. For instance, it is 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.

 Advantages of non-quenched and tempered steel product:

Stable and uniform mechanical properties;

Save manufacturing expenses and avoid waste in the tempering process;

Shortened processing periods, enhance productivity and reduce the occupied capital;

Low processing cost, needless quenched and tempered process and the second turning;

The steel directly turning saves the logistics cost;

Energy conservation: Production no quenched and tempered process greatly saves the energy consumption;

Environmental protection: Production no quenched and tempered process meets the requirements of environmental protection.
