In annealing steel is heated to a temperature which is slightly above the critical temperature, followed by slow cooling. Annealing is used to reduce hardness and increases ductility. Normalizing. Normalizing is similar to annealing, but in normalizing the heated steel is cooled in air.
Background Unit: Heat Treatment of Steel Introduction Figure 1 shows a slightly simplified version of the Fe- Fe3C alloy system.
