This process refines the grain structure, improves mechanical properties, and enhances machinability. 3. Quenching: Steel billets are rapidly cooled by immersing them in a quenching medium (e.g., water, oil, or polymer) after being heated to high temperatures. This creates a hardened and stronger steel with improved wear resistance, but brittleness may increase. 4. Tempering: After quenching, hardened steel billets are reheated to a specific temperature and then cooled in still air. Tempering relieves residual stresses, reduces brittleness, and improves toughness and ductility. 5. Austempering: Steel billets are quenched in a molten salt bath or another medium just above the critical range and held at that temperature until the desired transformation occurs. Austempering results in high strength, improved ductility, and reduced distortion. 6. Martempering: Similar to austempering, martempering involves a shorter holding time at the quenching temperature. This process produces a steel with high strength, toughness, and reduced distortion. 7. Case hardening: Carbon is added to the surface layer of steel billets through carburizing or nitriding. This forms a hardened case with increased wear resistance while maintaining a more ductile core. These examples illustrate some of the heat treatment processes applicable to steel billets.
