There are several different types of heat treatments for steel, including annealing, normalizing, quenching, tempering, and case hardening. Annealing involves heating the steel to a specific temperature and then slowly cooling it to relieve internal stresses and improve its ductility. Normalizing is similar to annealing, but the steel is cooled in still air instead of a controlled environment. Quenching involves rapidly cooling the steel to increase its hardness, while tempering is a subsequent heat treatment that reduces the brittleness caused by quenching. Case hardening is a process where only the outer surface of the steel is hardened, making it more wear-resistant while maintaining a tough core.
