The required mechanical property input from the required mechanical property setting means via the input means is compared with the mechanical property standard value and experimental data in the mechanical property standard memory, and the comparison result is judged as to whether or not the corresponding standard exists. Material classification / standard material standard comparison part to be entered in the part,
Wherein a judgment of the presence or absence of the relevant standard, "present" the request material fall into the third determination of that to extract criteria materials applicable standards in the case of on the basis of a comparison result in the material classification / reference material specifications comparator unit With a controller consisting of parts,
The controller corresponds to the material standard of the chemical component corresponding to the required chemical component, the material standard of the mechanical property corresponding to the required mechanical property, and the required material classification by the first, second and third determination units. A request that is a comparison value of each comparison part of the chemical component / material standard comparison part, the mechanical property / material standard comparison part, and the material classification / standard material standard comparison part when the standard material standard is not extracted. By sequentially changing the chemical composition and the required mechanical properties within an allowable range and searching for the corresponding standard, the material standard closest to the chemical composition required in the product design planning stage and the required machine Material selection system characterized by being a controller that extracts the material standard closest to the physical properties.
