A Brief Introduction To The Heat Treatment Method Of The Piston Rod Material
Nov 10, 2017

【Summary】 When it comes topiston rod material, we may first think of the 45# steel. The heat treatment process includes preparing heat treatment, low temperature spheroidizing annealing and quenching, critical temperature quenching and high frequency quenching. The internal tissue and properties of the steel are changed by the heating, heat preservation and cooling of the steel in solid state。 


The surface hardness of the 45# piston rod material  can reach 45 ~ 52 HRC after quenching. In this way, it can obtain a series of comprehensive mechanical properties such as high strength and toughness.


If the heat treatment process of 40Cr is used, after the preparing heat treatment, the stress in the workpiece should be eliminated, the quenching and tempering operation should be carried out, and the quality of the workpiece should be inspected. 40Cr steel is a kind of thermal refined steels with low hardenability, which has high strength and good plasticity.


40Cr piston rod material has strong toughness and mechanical properties. It can improve the plasticity and toughness of steel by appropriate tempering, and make its strength, hardness, toughness and plasticity fit properly, and adapt to the performance requirements of piston rod.


2Cr13 piston rod material has good mechanical processing performance. Because of this, after a series of heat treatment, it will have better corrosion resistance and strong toughness. In order to maximize the 2Cr13 piston rod material, pay attention to its heating temperature and time.
