Low carbon steel is cheap and easily available, having all material properties that are acceptable for many applications. Heat treatment carried out on low carbon steel is to improve the properties such as ductility, toughness, machinability, refine grain structure, strength, hardness, tensile strength and to relive internal stress developed in the materials during cold or hot working. An AISI8620, American standard mild steel was subjected to different heat treatment operations. Low carbon steel with varying mechanical properties that can be utilized in different engineering applications was obtained.
