6. Annealing treatment
The aim of annealing is to give the steel a structure and a level of softening that will make it easier to process. The expected consequences of this treatment are :
easier machining;
easier shaping by mechanical transformation;
a structure suitable for subsequent heat treatments.
The main types of annealing are described in the articles on heat treatment of tool steels
