HY4520 HY4700 Micro Alloy Steel Rod With Ferrite And Pearlite Structure
Product Description
1. The mechanical property of micro alloy steel rod is stable and uniform
2. Production no quenched and tempered process can greatly save the energy consumption.
3. Production no quenched and tempered process meets the requirements of environmental protection
4. Micro alloy steel rod mainly used in mechanical manufacturing for the directly turning part of shaft
and rod, ect
5. The processing period is shortened, and the productivity is enhanced and the occupied capital is
reduced..
6. The processing cost is low, there is no need of quenched and tempered process and the second
turning but the mechanical property is correspond to quenched and tempered piston rod
