This paper describes fatigue properties of plastic deformed stainless steel. Stainless steel has good properties whish are excellent corrosion resistance, tensile strength in high temperature etc. therefore, it has been used for industrial and structural material because of property of maintenance free. Fatigue properties are considered to be one of the most important. There are few reports about which kinds of subjects. Especially, this paper describes fatigue properties of plastic deformed stainless steel which rise remarkably its fatigue limit.
