Technology comment
The annealing process involves heating carbon steel above the critical temperature and then slowly cooling it. This process helps eliminate internal stresses in the steel, reduce hardness, and increase ductility and toughness. Such treatment makes annealed carbon steel coils easier to form during processing, especially suitable for applications requiring deep drawing or bending.
