    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.
