Processing
Heat treatments
Increases hardenability (the
higher the carbon content the better the
hardenability)
nQuenching – medium
or high carbon content
nheat to critical temperature, dip in oil or water
natomic structure, magnetism and electrical resistance change
nTempering – quench
first, reheat then slowly cool
nAnnealing – heat to
critical temperature and slowly cool
neliminates residual
stresses created during forming the part
