| Popis: | In the context of increased pace of modern production, the role of heat treatment is increasing, as it is the main method for producing steels with a given structure and mechanical properties. Parts used in production must have a long service life not only at room temperature, but also have high strength characteristics at low and high temperatures. In this regard, special attention is paid to steel used for the manufacture of such parts. One of them is steel grade St52-3 (rus 17Г1C). The aim of the work was to determine the effect of quenching at various temperatures onto corrosion resistance of St52-3 steel. To achieve this goal, tasks such as studying the effect of different tempering temperatures of St52-3 steel on the value of hardness according to the Rockwell method were undertaken. After-treatment gravimetric studies were performed to identify the temperature regime of tempering that minimizes the corrosion rates. It was shown that after tempering, the hardness of the samples decreases with increasing temperature. To assess the corrosiveness of the medium for the test samples, the mass and depth corrosion indicators were calculated. The maximum corrosion rate is observed during quenching and subsequent tempering at a temperature of 300 °C, the minimum at a tempering temperature of 500 °C. |
