Tensile test and a micro stretch bending test were conducted to study the behavior of the stainless steel 304 foils for micro sheet forming. In this study, 4 different thicknesses stainless steel 304 foils were used as specimens while 5 micro deep draw dies were used for micro stretch bending experiments. By observing the tensile test results, it can be found that the stainless steel 304 foils with T/D (thickness/average grain diameter: the numbers of grains throughout the metal thickness) >10 has less formability than those with T/D<10. By observing the results of the micro stretch bending experiments, it can be concluded that the stainless steel foils with T/D<10 have less springback amount and smaller springback deviation in comparison with those with T/D>10. In order to have a better formability and less springback, it is recommend having the stainless steel 304 foils with T/D<10 for micro sheet forming application.
