Heat Treatment Processes Hardening. Hardening involves heating of steel, keeping it at an appropriate temperature until all pearlite is transformed into austenite, and then quenching it rapidly in water or oil. The temperature at which austentizing rapidly takes place depends upon the carbon content in the steel used.
After steel has been tempered, it can be easily shaped, cut and filed, which is important in the manufacturing process. Outside of manufacturing, heat treatment of steel is carried out in metal workshops for students. When metal is tempered, it turns different colors based on the amount of heat to which it is exposed.
