WebMay 31, 2024 · There are five basic heat-treating processes: hardening, tempering, annealing, normalizing, and case hardening. Although each of these processes brings about different results in metal, all of them involve three basic steps: heating, soaking, and cooling (Fig. 1.45). What is the purpose of annealing? WebOften, annealing is the final step of manufacturer if a part maker such as a company deep drawing material orders the material in the annealed form. Annealed material is typically softer and easier to work with for operations with tooling setups that may break or deform easily. When material is ordered to DQ (deep draw quality), this is just a ...
