The mechanical properties of a material change with the cross-sectional form, size and test atmosphere of the material. For this reason, the intelligent universal tester equipped with an intelligent control program was used as a testing machine. In order to measure the mechanical properties of the material, the test conditions must be chosen appropriately according to the various states of the material. In deciding the test conditions, elastic or plastic behaviors must be distinguished clearly. The elevated tensile speed V_1 and the step stress σ_<st> reduced. In this study, the optimum test conditions were elucidated using SUS303 stainless steel specimens of two different chemical compositions and outer diameters.
