description: This work is devoted to the study of the structure and maraging steel obtained in the production of rolling rings. The task of the work is to determine the reasons influencing low values of impact toughness in some MAS samples from one batch. The work was carried out on the basis of "CNIIM", where a significant part of the actual material was collected: the results of microstructural, chemical, X-ray structural analysis. Studies were carried out to determine the factors affecting the mechanical properties of steel grade EK165-ID. The analysis was carried out with the help of optical and electron microscopes, X-ray diffractometer, energy dispersive and emission analyzers, image analysis software Thixomet. As a result, the structures, chemical composition of the available samples of maraging steel were analyzed. The reasons for the decrease in the results of impact bending tests were determined. Recommendations on elimination of the main cause of instability of properties, reduction of concentration of non-metallic inclusions were developed.
