Heat Treatment Normalizing
Heat treatment is a group of industrial and metalworking process used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical.
Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve a desired result such as hardening or softening of a material.
Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, normalizing and quenching.
We would like to introduce Annealing Heat Treatment process for Investment casting, sand casting, precision casting, lost wax casting and hot forging process for you. If need OEM casting parts, please contact us email@example.com or visit www.guokuncasting.com
Normalizing is a technique used to provide uniformity in grain size and composition throughout an alloy. The term is often used for ferrous alloys that have been austenitized and then cooled in open air. Normalizing not only produces pearlite, but also martensite and sometimes bainite, which gives harder and stronger steel, but with less ductility for the same composition than full annealing.
