Development of technologies for the production of the very fine structure is currently very intensively accelerated. Even in scientific research, it is recognized that precisely controlled forming processes, including special processes, enabling control of technological parameters with regard to the structure refinement, and tied with the strengthening of materials, currently had the highest gradient of utilization efficiency of the scientific research findings in practice. New forming equipment using the process SPD is currently installed in the laboratory for the development of new technologies at the Faculty of Mechanical Engineering – VSB-TU Ostrava. The paper analyses the effects of the values of angles of the newly developed forming tools on the achievement of mechanical properties in selected low carbon steels in the SPD process. The following types of steels were verified experimentally: DC01 and S355 - strip sheet with dimensions 58 (width) x 2 (thickness) x 1000 (length) mm. The paper also evaluates the influence of severe plastic deformation (SPD) on strengthening these steels at different values of the angle in the forming tool. The influence of new geometries of forming tools for improving mechanical properties has been unequivocally demonstrated.
