On this page, we have summarized specialized terms related to heat treatment in an easy-to-understand manner. "Annealing," also known as "softening," is a heat treatment process where metal is held at a high temperature and then slowly cooled. It is similar to quenching, but differs in that it does not expect effects such as precipitation. The main purpose of this process is to refine the microstructure of steel that has been processed at high temperatures or to soften the material. In addition, terms such as "atmosphere furnace," "tempering," and "bonding" are also included. You can view detailed information through the related links.
