8mm 25mm Hydraulic Cylinder Piston Rod Induction Hardened

As we know, chrome-plated rods are a very widely used connecting part, which can be applied to almost all mechanical products. Its commonly used materials mainly include No. 45 steel, 40Cr, 2Cr13... and other steels, and these steels need to go through certain treatment procedures, such as electroplating, heat treatment..., etc., in order to obtain special properties to meet certain requirements. some needs. Therefore, it must be heat-treated to obtain sufficient strength and surface hardness and the ability to resist corrosion, friction, fatigue, and seizure. The following editor will introduce the heat treatment method of chrome-plated rod material for you.
1. No. 45 steel: heat treatment process: preliminary heat treatment - low temperature spheroidizing annealing - quenching - critical temperature quenching - high frequency quenching
No. 45 steel is a kind of medium carbon steel. The heat treatment of 45 steel chrome-plated rods is mainly to change the internal structure and performance of the steel through heating, heat preservation and cooling of the steel in a solid state. After quenching, the surface hardness can reach 45-52HRC, and comprehensive mechanical properties such as high strength and toughness can be obtained.
2. 40Cr:
Heat treatment process: preparatory heat treatment - eliminate internal stress of workpiece - quenching and tempering operation - workpiece quality inspection
40Cr steel is a quenched and tempered steel with low hardenability, which has the characteristics of high strength, good plasticity, strong toughness and good mechanical properties. Moreover, it can improve the plasticity and toughness of steel through proper tempering, so that the strength, hardness, toughness and plasticity can be properly matched, so as to meet the performance requirements of chrome-plated rods.
3. 2Cr13:
Heat treatment process: preliminary heat treatment process - quenching and tempering treatment - stress relief treatment - high frequency quenching, low temperature tempering
2Cr13 steel has good machinability, so it can have excellent corrosion resistance and good toughness after heat treatment. In order to maximize 2Cr13, it is necessary to correctly determine the heating temperature, time, holding time, and cooling method, so that the correct heat treatment process can be used to make the surface of the heat-treated 2Cr13 chrome-plated rod not only have high hardness and high wear resistance , high pitting resistance, high fatigue strength, high strength and toughness, so as to meet the quality requirements of chrome-plated rods.
