Explaining heat treatment! By using different methods according to the purpose, it is possible to impart various properties to the products.

In this column, we will provide a detailed explanation of four representative heat treatment methods: "quenching," "tempering," "annealing," and "normalizing," aimed at those who have questions such as, "I want to know how to differentiate between the commonly used heat treatments of quenching, tempering, annealing, and normalizing," or "I want to use heat treatment to improve the quality of my company's products, but what methods would be best?" Each of the four heat treatments utilizes heat to change the structure of the steel material, and they are differentiated to achieve desired properties such as hardness and toughness. We will introduce the characteristics, applications, and temperature patterns of each heat treatment method in detail. *For more detailed information about the column, please refer to the related links.
