What Is Heat Treatment?

Heat treatment is used to toughen metals and improve their mechanical properties. By carefully controlling time and temperature during tempering, the steel’s microstructure is transformed from brittle martensite to tougher phases such as bainite or ferrite, achieving a balanced combination of strength and durability.
