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? WebApr 4, 2024 · To anneal or normalise a metal: An annealed or normalised metal can be returned to a softer, more ductile condition if it has become harder due to heat or work. To harden a material: A material is heated above a specific temperature for this hardening. A substance like water or oil is then used to quench the material quickly.
