The production of many types of metal products includes a complex of deformation and thermal operations, therefore, when designing and improving production processes, knowledge of the strength and plastic properties of the metal being processed is necessary. The purpose of this work was to research the plastic deformation resistance of billets made of 40KhN2MA structural alloy steel in various states, used for the production of a number of types of metal products. As a result of the research, graphical dependences and histograms were constructed that reflect the specificsof the deformation behavior of steel 40KhN2MA during pressure treatment. In the course of the work, statistical dependences of the influence of the degree of deformation of samples from steel 40KhN2MA on the resistance to deformation in relation to various condition were obtained, which can be used to forecasting the strength properties of the metal during processing.
