Introducing the basics of heat treatment! The changes in structure vary depending on the holding temperature after reheating.
"Tempering" is a heat treatment performed to impart toughness to steel that has been hardened by quenching. It involves reheating the steel from a martensitic state, holding it at a certain temperature for a specific period, and then cooling it slowly. After reheating, the changes in the microstructure vary depending on the holding temperature. Tempering at approximately 600 degrees Celsius yields a sorbite structure, while tempering at around 400 degrees Celsius results in a troostite structure. Additionally, the series of processes where the steel is tempered at a temperature that produces a sorbite structure after quenching is specifically referred to as "quenching and tempering." [What is Tempering] - A heat treatment performed to impart toughness to steel that has been hardened by quenching. - The process of reheating the steel from a martensitic state, holding it for a certain period, and then cooling it slowly. - Tempering at approximately 600 degrees Celsius yields a sorbite structure, while tempering at around 400 degrees Celsius results in a troostite structure. *For more details, please refer to the PDF document or feel free to contact us.*
