The overall assessment of the influence of chemical composition and structure of sheet ST3SP steel samples on quality of the sheets, rolled by the existing technology on a continuous wide strip mill 1700 was run. The study shows that the control of the hardness of hot rolled strip by changing its chemical composition is only possible through the establishment of a sufficiently accurate content of carbon, manganese and silicon, as well as strictly observe the temperature of rolling, cooling and coiling on the run-out table.
