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.
Flame-hardening is an ideal, time-tested method for steel hardening. And there are several types of steel that work well for the flame-hardening process. One example is hardening 4140 steel. Another is hardening 1045 steel. Flame-hardening cast iron has also been done with success. The clutch plate shown in the photo below is made of cast iron, as is the cam shaft sample shown to the right.
