Before the heat treatment, we bend a hangar until it breaks
noting the force required to bend it - usually 3-4 bends.
(This is repeated after the heat treatment.)
A quench & temper starts with heating to red hot & quenching in water... 
Spark testing to identify carbon content in steels
... then reheating slowly to purple, followed by annealing or normalizing
