Description

High Strength Steel Thread Rod Instead Of Quenched And Tempered Rod For Cylinder

Product Description
1. Stable and uniform mechanical properties.
2. Save manufacturing expenses and avoid waste in the tempering process.
4. Shortened processing periods, enhance productivity and reduce the occupied capital.

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