Stress Relieve Anneal: Sub-critical thermal treatment
applied after cold drawing. Removes residual stresses in the bar and may also
increase yield strength.
Straightening: Bending applied to bar through a set of rolls. Improves
straightness.
Cutting: Separates into desired lengths by cold shearing or sawing.
Improved length tolerance, end distortion and perpendicularity.
Chamfering: Cutting a taper and end-facing the bar. Eliminates end
distortion and improves bar feeding.
Annealing: Heating above the critical temperature and slow coating the
bar. Controls microstructure and softens the bar.
Normalizing: Heating above the critical temperature and air cooling the
bar. Improves uniformity of microstructure.
Quenching and Tempering: Heating above the critical temperature and
quenching the bar in oil or water followed by a tempering operation increased
strength, hardness and toughness.
