In this study, to evaluate the strain rate sensitivity of deformation behavior in SUS304 as well as its fracture mode, the SP test and tensile test at different deformation rate would be carried out. The fracture mode of specimen after tests at different deformation rate will be observed by SEM(Scanning Electron Microscope).
