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.
Heat Treatment, annealing, and tempering are three of the most well-known methods for treating metals. Depending on the treatment used, a material may become more or less brittle, harder or softer, or stronger or weaker. The method chosen depends on the desired characteristics of the material.
