Abstract

The article presents the findings of an investigation into the mechanical properties of wheel steel billets of T grade (selected from continuous cast billets and ingots with diameters of 455 and 472 mm, respectively) in the initial cast state and after deformation by screw piercing. Billets with a diameter of 100 mm, from the peripheral and central regions of the continuous-cast billet and ingot, were selected for investigation. The billets were subjected to piercing at feed angles of 12 and 14° with a reduction ratio within the range of 1.26–1.68. The results show that after piercing, the deformed metal acquires enhanced plastic properties compared to the initial state, with more pronounced changes in the longitudinal direction compared to the properties in the tangential direction. The differences in the values of strength, plastic properties, and impact toughness between the metal of billets from the center and periphery of the continuous cast billet and the ingot were reduced.
