Stainless steel is an alloy steel of Fe with over 11% of chromium. It has corrosion resistance by passive coat on the surface of the steel and lasts beautiful conditions longer.Corrosion resistance of stainless steel is improved as chromium content rate becomes higher and passive coat becomes better.

Stainless steel is applied to a variety of field, e.g. tableware, kitchen tool, construction material, parts for machinery, medical appliances, chemical equipment and aircraft.Stainless steel type has 304, 316,420,430 and so on. During stainless steel manufacturing process, heat treatment is an essential part. 

Stainless steels are generally heat-treated based on the stainless steel type and reasons for carrying out the treatment. Heat treatment methods, such as stress relieving, hardening and annealing, strengthen the ductility and corrosion resistance properties of the metal that is modified during fabrication, or generate hard structures capable of tolerating abrasion and high mechanical stresses.

Heat treatment of stainless steels is mostly carried out under controlled conditions to avoid carburization, decarburization and scaling on the metal surface.
