High Strength Hard Chrome Plated Rod Micro Alloy Steel Grades
 

 
Product Description


1. The micro alloy steel products are developed on the basis of proprietary technology of the control

    rolling and cooling for substituting quenched and tempered piston rods with a variety of mechanical

    performance requirements.

2. Micro alloy steel rod mainly used in mechanical manufacturing for the directly turning part of shaft
   and rod, ect. For instance, it is used for manufacturing injection molding machine draglink, engineering

    machinery push rod and hydraulic prop with the feature that hardened and tempered steel machanical

    property needless quenched and tempered process
3. The mechanical property is correspond to quenched and tempered piston rods or over them and

    very uniform on the whole cross section.
4. Hardness is more uniform on the whole cross section than quenched and tempered piston rods

5. Turning performance is commensurate to quenched and tempered piston rods or be superior to them.
6. Micro structure: Ferrite and pearlite with fine and uniform grain size.
7. The processing period is shortened, and the productivity is enhanced and the occupied capital is
    reduced..
8. 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
