The key to the piston rod quenching and tempering treatment
Aug 03, 2018

In actual processing, quenching and tempering is a relatively critical process. Therefore, after the quenching and tempering treatment, the piston rod not only has its toughness improved significantly, but also its comprehensive performance has been improved. The purpose of surface hardening is to obtain a high surface hardness to support the surface chrome plating layer, thereby improving the wear resistance and corrosion resistance of the piston rod.


Usually, in the process of heat treatment, the stress relief annealing process is often arranged before the plating process after the grinding process to fully eliminate the residual stress inside the piston rod, and improve the plating quality and product qualification rate. We know that the actuator is used to perform reciprocating motion, drive engineering machinery to complete various functions, and key transmission parts with high technical requirements, and to withstand large tensile stress during work.


Therefore, in the process of heat treatment, the treatment effect will directly affect the intrinsic quality and mechanical properties of the piston rod. The purpose of quenching and tempering treatment 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, which is ready for subsequent surface quenching.http://www.xhychromerod.com/
