Changes in the structure of steel due to quenching and the hardening mechanism, the influence of carbon content, and its applications.
[Reproduction of Private Spring Preparatory School Lecture 54] Changes When Hardening is Done! Explanation of Carbon Content and Hardness from Hardening.
Today, let's investigate the changes that occur when quenching. First of all, it is absolutely necessary to heat the steel to a red heat for quenching. The temperature for this is the standard quenching temperature found in the familiar JIS spring steel material table. However, this is an example for heat treatment of tensile test specimens. In reality, whether it is a leaf spring or a coil spring, there is a forming process involved, so the temperature at the end of the forming process corresponds to this temperature. Now, let's consider what significance this quenching temperature has. *For detailed content of the article, please refer to the PDF. For more information, feel free to contact us.*
