Chrome Plating Micro Alloy Steel Piston Rod With High Properties
Product Description
1. 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
42CrMo4, 40Cr and CK45 with a variety of mechanical performance requirements.
2. the mechanical property is correspond to quenched and tempered 42CrMo4, 40Cr and CK45 or over
them and very uniform on the whole cross section.
3. It is mainly used for manufacturing injuection 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.
4. Turning performance: Turning performance is commensurate to 42CrMo4, 40Cr and CK45 or be
superior to them.
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.
