Material selection of pneumatic cylinder piston rod

October 25, 2024
When processing the piston rod of a Pneumatic Cylinder, if 45 steel is used. Under normal circumstances, the load on the piston rod is not large, which means it will be made of 45 steel. Due to the fact that 45 # steel is more commonly used for medium carbon quenched structural steel, it is because it will have higher strength and better machinability.
 
When producing piston rods from 45 # steel, especially after appropriate heat treatment, it is more practical to obtain a certain degree of toughness, ductility, and related wear resistance. Therefore, for 45 # steel, in fact, it is one of the most commonly used important materials in piston rod processing.

In addition, in the processing of piston rods, if 45 # steel is used, the piston rod will be manufactured using 40Cr steel when the load is relatively large. Due to its medium carbon quenched and tempered nature, 40Cr steel has good hardenability and low temperature impact toughness. Especially after quenching, it will have better overall mechanical properties.
 
In this way, what we actually need to pay attention to is that it can ensure that the piston rod has sufficient working strength. In view of this, using 40Cr steel to manufacture piston rods is commonly used for high impact or heavy-duty transmissions that require large piston rod equipment.

Finally, in fact, we should pay attention to the above description of materials, which are more commonly used in the processing of piston rods. However, in addition to the two materials used for machining piston rods mentioned above, there are also GCR15 steel or SUS304, which are directly used for manufacturing machining materials on piston rods.
