Recently, high-Mn steels have been developed with excellent mechanical properties such as high strength and ductility at very low temperatures. Structural materials for cryogenic applications are often accompanied by plastic deformation such as cold working, bending and drawing when making products. Especially, a cold working process of high-Mn steel is effective method to increase yield and tensile strength. However, negative effects such as undesirable anisotrpy properties and reduction of ductility are occured. In the case of cold rolled high-Mn steel, there is little research on mechanical properties of anisotropy of microstructure after heat treatment. In this study, we evaluated the effects of annealing treatment on the anisotropy behavior for cold worked high-Mn steels. Despite the recrystallization of cold worked high-Mn steels after the heat treatment, mechanical properties such as tensile and Charpy impact test was anisotropic properties due to the inhomogeneous microstructure of the rolling orientation.
