Each piston rod has passed 32 processes.
The material of piston rod is 38CrMoAL and is ion-nitrided, which harden the surface of the piston rod.
To some gases contain significant amounts of H2S or CO2,the piston rod will require to be processed specially.

Features:
Precise processed,
Surface hardened processed,
Lone service time,
High intensity,
Strong impact force.
