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.
Hold the work piece at the hardening temperature until it is completely and uniformly heated. QUENCHING. A2 is an air hardening steel and will develop full hardness on cooling in still air. To avoid scaling of the work piece surface, controlled atmosphere or vacuum furnaces are recommended.
