Heat Treatment
Heat treatment is a controlled process of heating and cooling metals and alloys to alter their physical and mechanical properties without changing their shape. The primary goal of heat treatment is to improve characteristics such as hardness, strength, ductility, toughness, and wear resistance to meet specific engineering requirements. Common heat treatment processes include annealing, quenching, tempering, normalizing, and case hardening. During heat treatment, the metal is heated to a specific temperature where its microstructure changes, then cooled at a controlled rate to achieve the desired properties.
Stress Relieving
Stress relieving is a heat treatment process used to reduce or eliminate residual stresses that develop in metal components.
Hardening
Hardening is a heat treatment process used to increase the hardness and strength of metals, particularly steels.
