Heat treatment and stress elimination method of hydraulic piston rod
Nov 05, 2018

Heat treatment is required during the processing of hydraulic piston rods, usually after annealing and forging. The heat treatment can further improve the performance of the hydraulic piston rod, and can improve its overall toughness, achieve good performance, and help prevent deformation in later use.


After processing in different processes, a certain amount of stress may be generated inside the hydraulic piston rod. Therefore, it is necessary to take certain measures to remove the internal stress. In fact, during the processing, the quenching and tempering process is an important step. The purpose of this process is to make the piston rod have comprehensive mechanical properties with good matching of strength, hardness, plasticity and toughness. The internal structure is uniform and fine tempered sorbite. Prepare for subsequent surface quenching.


As for the stress removal, it is usually arranged before the electroplating after the grinding process so that the residual stress inside the hydraulic piston rod is sufficiently eliminated. And help to improve coating quality and product qualification rate.https://www.xhychromerod.com/
