Length 1m - 8m Micro Alloyed Steel Rod For Mechanical Manufacturing
Product Description
1. ISO9001:2008, stable and uniform mechanical properties, the directly turning saves the logistics cost.
2. Save manufacturing expenses and avoid waste in the tempering process.
3. Shortened processing periods, enhance productivity and reduce the occupied capital
4. The mechanical property is correspond to quenched and tempered 42CrMo4, 40Cr and CK45 or over
them and very uniform on the whole cross section.
5. It can be 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.
6. Production no quenched and tempered process meets the requirements of environmental protection
