Presented paper is focused on comparison of three types of steel for production of tubes with shaped internal surface for applications in energy producing industry. Simulations were performed in Deform-3D software with usage of finite elements method. Steels 20MnCr5, C10 and 34CrNiMo6 were selected for simulations. Obtained results are showing deformation, stress, strain and temperature during cold drawing of tubes with shaped internal surface and also resulting comparison of three tested materials depending on the course of load during the forming process. As a conclusion of the presented research is comparison of presented three steels according to the simulation results. Presented paper has potential to increase knowledge base in the area of forming tubes with shaped internal surface. Obtained results can contribute to a proper selection of tool material, coatings and process set up for forming process of tubes with shaped internal surface. [ABSTRACT FROM AUTHOR]
