[Metal Heat Treatment Guide] What is Quenching?

Heat treatment that changes the state of martensitic structure! A method used when forging Japanese swords!

"Quenching" is a heat treatment process that involves heating steel to an austenitic structure and then rapidly cooling it in water or oil, transforming it into a martensitic structure. Depending on the cooling medium, it is referred to as water quenching or oil quenching, and it is also a method used in the forging of Japanese swords. This process is performed to increase the hardness of the steel, but it reduces toughness, so it is common to perform tempering after quenching to achieve ductility. 【What is Quenching】 ■ A process that changes the state of steel from an austenitic structure to a martensitic structure by heating it and then rapidly cooling it in water or oil. ■ A method used in the forging of Japanese swords. ■ The quenching effect cannot be expected unless the carbon content is 0.3% or higher. *For more details, please refer to the PDF document or feel free to contact us.

Metal Heat Treatment Guide: What is High-Frequency Quenching?

A suitable method for steel with a carbon content of 0.3% or more! Introduction to the basics of heat treatment.

"High-frequency quenching" is a heat treatment method that induces electromagnetic induction in metals using high-frequency electromagnetic waves, overheating the surface to perform quenching. This process hardens only the surface of the metal, increasing its hardness while maintaining the original state of toughness in the interior, allowing for the creation of materials rich in flexibility. Depending on the type of steel, the surface hardness generally increases by about 1 to 2 Rockwell hardness (HRC) compared to conventional quenching. 【What is high-frequency quenching】 - It is possible to create materials rich in flexibility by hardening only the surface of the metal to increase hardness while maintaining the original state of toughness in the interior. - The surface hardness generally increases by about 1 to 2 Rockwell hardness compared to conventional quenching. - This method is mainly suitable for steel with a carbon content of 0.3% or more. *For more details, please refer to the PDF document or feel free to contact us.
