How to choose the material of quenched and tempered piston rod

In order to increase the service time of the piston rod and reduce the wear of the piston rod, 38crmoalan alloy structural steel is selected as the blank.

Judgment of blank shape and dimension:

1. Blank shape

According to the machining accuracy requirements of each part in the part drawing, the dimension tolerance grade of forgings is 8-12, and the cylindrical blank is selected.

2. Dimension of blank base wood

Because the production method of blank is free casting, according to the dimension requirements of quenched and tempered piston rod part drawing and practical processing requirements.
