Dtabase for the stregth of materials is desired strongly as it is a powerful tool for searching out strength date. But as for fatigue properties,it is rarely possible to get suitable date to design or maintain machines and structures foe a particular material ans testing conditions directly from the database. In general, its fatibue properties must be estimated from the date obtained under similar testing condition. In this paper, a method for prediating the minning properties in fatigue database is discussed. Good correlation between the tensile property data and the exponents or coefficients of the equation for cyclic stress-strain curves and Manson-Coffin law were obtained for steels specified by JIS for machine structural used. By using these relationsships, S-N curves under uniaxial tension-compression can be predicted for steel, if their tensile properties are known. A conversion method of fatigue strength is also proposed between rotating bending and uniaxial conditions or between reversed torsion and uniaxial conditions.
