Piston Rod Material Selection

When processing the piston rod, if 45 # steel is used. Under normal circumstances, in terms of the load on the piston rod is not big, that is, will be used to make 45 # steel. As 45 # steel is more commonly used in a medium-carbon quenched structural steel, in terms of this, it is because it itself will have a higher strength and better machinability.

In the 45 # steel production of the piston rod, especially after it has been properly heat treatment, it would be more realistic that is to obtain a certain degree of toughness, ductility and related wear resistance, in view of this, on the 45 # Steel, in fact, it is actually one of the most commonly used important material when the piston rod in the processing.

Furthermore, the processing of piston rod, if the use of 45 # steel, the piston rod when the load is relatively large, that is, the use of 40Cr steel for manufacturing. As 40Cr steel is a medium-carbon quenched and tempered steel, its own hardenability is better, its low temperature impact toughness. Especially when it is after quenching, it will have a better overall mechanical properties.

In this way, we actually have to pay attention to that it can guarantee that the piston rod can have enough work intensity. In view of this, the use of 40Cr steel for the manufacture of a piston rod is often the case that it will be used for high impact or heavy-load transmissions that require large piston rod equipment.

Finally, in fact, we should pay attention to the above description of the material, that is, when the piston rod processing more commonly used materials. However, in addition to the above-mentioned two kinds of materials for processing piston rod, there is also there will be GCR15 steel or SUS304, which is directly used to make the processing material on the piston rod.
