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.
The most common question about heat treating What is the difference between case hardening and through hardening? The most common metal is steel which is available in many different alloys. The most common type of steels are: 1: Those which may be grouped under the heading mild steel and generally contain less than 0.25% carbon. 2: Those classed as medium to high carbon which contain carbon over 0.25%. medium carb. 0.25% - 0.5%.
