Normalizing: The steel billet is heated above its critical point and then allowed to cool in still air. Normalizing refines the grain structure of the steel, resulting in improved mechanical properties and uniformity. 3. Quenching: This process involves rapidly cooling the steel billet from a high temperature by immersing it in a quenching medium, such as water, oil, or polymer. Quenching creates a hardened structure, thereby increasing the steel's hardness and strength. 4. Tempering: After quenching, the steel billet is heated to a lower temperature and slowly cooled. Tempering reduces the brittleness caused by quenching and improves the toughness, ductility, and machinability of the steel. 5. Austempering: The steel billet is quenched to a temperature slightly above the martensite transformation range and held at that temperature until it transforms to bainite. Austempering results in a structure with improved strength, toughness, and wear resistance. 6. Martempering: Similar to austempering, the steel billet is quenched into a medium slightly above the martensite transformation range and then held until it cools below that temperature. Martempering produces a structure with enhanced toughness and reduced distortion compared to conventional quenching. These examples represent only a fraction of the numerous heat treatment processes employed for steel billets. The selection of the appropriate process depends on the desired mechanical properties and application requirements of the steel.
