    Applications:

     

    Single-acting/double-acting hydraulic cylinders --- Garbage trucks, dump trucks, agricultural equipment, ships, mines, drilling platforms, machinery in harsh environments

     

    Crafts Process Hardening Force Remove

     

    In the whole crafts process, there are 2 times remove hardening forces: the first remove hardening force in the heat treatment process, hardening force remove is about 80%; the second remove hardening force in the surface treatment process, hardening force remove is about 90%-95%. Therefore, the piston rod is not easily deformed during use or transportation.
