Hydraulic cylinder is an important executive element in the hydraulic system of construction machinery, used to perform reciprocating motion and drive construction machinery to complete various functions. The piston rod is a key force transmission part with high technical requirements for connecting the piston and working parts in the hydraulic cylinder. It needs to withstand greater tensile stress during the working process. Therefore, the piston rod must have sufficient strength, rigidity, and toughness. It is easily worn out by abrasive particles and must have high wear resistance.
