Microalloyed Steels Chrome Rod For Hydraulic Cylinders With Energy Conservation
Product Description
1. Environments protection: Production no quenched and tempered process meets the requirements of
environmental protection.
2. Energy conservation: Production no quenched and tempered process greatly saves the energy
consumption.
3. The micro alloy steel products are developed on the basis of the proprietary technology of the control
rolling and cooling for substituting quenched and tempered 42CrMo4, 40Cr and CK45 with a variety of
mechanical performance requirements.
4. It is mainly used in mechanical manufacturing for the directly turning part of shaft and rod, etc
5. Stable and uniform mechanical properties.
6. Save manufacturing expenses and avoid waste in the tempering process
