45 steel piston rods use the advantages of high frequency quenching
Aug 01, 2018

The 45 steel piston rod is specially processed to provide high precision. In the processing process, one of the processes is high-frequency quenching. This process has many advantages. Firstly, it is not necessary to heat the whole. The deformation of the 45 steel piston rod is small, and the electric energy consumption is small. Moreover, the whole process is safe, environmentally friendly and pollution-free.


Secondly, the whole heating process is relatively short, and the oxidative decarburization on the surface of the 45 steel piston rod product is lighter. The surface hardened layer can be adjusted as needed and is easy to control. The heating equipment used can be installed on the machining line, easy to mechanize and automate, easy to manage, and can reduce transportation, save manpower and improve production efficiency.


Moreover, after the quenching treatment, the surface of the 45 steel piston rod product can generate a large compressive internal stress, thereby improving its fatigue breaking resistance. Not only that, the hardened martensite structure of the 45 steel piston rod product is finer, and the hardness, strength and toughness are higher, which ensures the reliability of the product.
