Quenching: Quenching is a rapid cooling process that involves immersing the steel billets in a quenching medium, such as water, oil, or polymer, after they have been heated to a high temperature. This process creates a hardened and stronger steel with improved wear resistance, but it may also result in increased brittleness. 4. Tempering: Tempering is a heat treatment process that follows quenching and involves reheating the hardened steel billets to a specific temperature and then cooling them in still air. This process helps to relieve residual stresses, reduce brittleness, and improve the toughness and ductility of the steel. 5. Austempering: Austempering is a heat treatment process that involves quenching the steel billets in a bath of molten salt or other medium at a temperature just above the critical range, followed by holding them at that temperature until the desired transformation occurs. Austempering produces a steel with high strength, improved ductility, and reduced distortion. 6. Martempering: Martempering is a quenching process similar to austempering, but with a shorter holding time at the quenching temperature. This process results in a steel with a combination of high strength and toughness, as well as reduced distortion. 7. Case hardening: Case hardening is a heat treatment process that involves adding carbon to the surface layer of the steel billets, typically through carburizing or nitriding. This process forms a hardened case with increased wear resistance, while maintaining a more ductile core. These are just a few examples of the heat treatment processes that can be applied to steel billets. The specific process used will depend on the desired properties of the final product and the type of steel being treated.
