Abstract

Initial blank for the production of calibrated rolled stock is hot-rolled steel, ductility of which is largely determined by the structure and quality of the rolled stock surface. Hot-rolled steel should have a high degree of surface cleanliness and defect-free cross-section. In this paper, using the example of hot-rolled steel 40X, it is shown that the structural condition and quality of the rolled stock surface largely determine the further quality of calibrated rolled stock for automobile long length bolt products made from it. In this case, the mechanical characteristics, which are the most widely used indicators of the steel quality, are largely determined by plastic and heat treatment, which change the structure at the macro- and microscopic level.
