2.2.4 Annealing
The term annealing refers to processes that reduces the hardness of the steel or gives it a
microstructure that is better suited for subsequent processes. The collective name annealing
usually means soft annealing, which is a process that maximizes the softness of the steel. It is
usually used for low alloy steels with a high carbon fraction. The steel is heated to 700-800°C
and kept at this temperature for several hours before it is slowly cooled down again. If cold
processing is carried out before the annealing, the process time can be significantly reduced.
