The effect of thermomechanical treatment on the structure and mechanical properties of the constructional steels (35 – 50)KhNMAF micro-alloyed with nitrogen is studied. Tensile and impact tests are conducted, the HV hardness is measured, and the structure of the steel is investigated by means of light microscopy and X-diffraction analysis. The regimes of thermal and thermomechanical treatment that make it possible to use this type of steel as a high-strength steel are determined.
