“…It is well known that cold rolling (during which severe plastic deformation usually occur) is a feasible and effective method to improve the yield strength of metals and alloys. Therefore, a lot of attention has been paid on the research of the cold rolling of austenitic stainless steels by the scholars all over the world [ 2 , 3 ]. The results indicate that deformation twins and slip lines could be formed during cold rolling, and micro-twins could impede dislocation movement, resulting in the increase in yield strength.…”

Austenitic stainless steel has high toughness and plasticity; however, it tends to exhibit low yield strength, which severely limits the widespread application of this steel. It can be strengthened by cold working; however, this will cause many defects in the structure. Therefore, annealing treatment must be carried out before use. In this paper, the effects of annealing treatment at different temperatures and times on the microstructure and mechanical properties of cold-rolled 305 stainless steel sheet were studied and the theoretical mechanism was further analyzed to provide better theoretical guidance for production and application. It was found that the microstructure grains obtained by annealing at 850 °C for 30 s were finer and more uniform, and the mechanical properties were also the best, which met the requirements of strong plasticity. Therefore, the rolling and annealing experiments could be carried out again under this annealing condition, and the requirements of the finished product could be finally obtained. At this time, the thickness of the plate was about 0.15 mm, the yield strength was 1238 MPa, and the permeability was below 1.02, which met the production requirements of the metal mask plate.
