The behavior of the SUS304L metastable austenitic stainless steel during deformation above and below M d temperature is systematically studied. At temperatures higher than M d , linear temperature‐dependent relationships are observed for tensile strength and elongation; whereas below M d , a sharp increase in these parameters is identified. A pronounced transformation‐induced plasticity (TRIP) effect is observed when the amount of martensite in the necked region becomes significant, resulting in a maximum point in the work‐hardening plot and enhancement of strength–ductility balance.
