<p>The structure and properties of sheet steel produced from low carbon martensitic steel using various controlled rolling regimes was investigated. Standard mechanical properties, ductility parameters, and steel toughness were determined. The effects of the temperature range and the final deformation temperature during the finishing stage of rolling on the structure and consequently on the strength properties, cold resistance, and fracture resistance of the rolled steel were investigated. The study reveals the relationship between the processing regime and the level of steel properties. The results indicate that reducing the final deformation temperature improves low-temperature impact toughness and increases the proportion of crack propagation work in the total fracture energy.</p>
