In the study of nitrided steel ВН11 a planned experiment was carried out, one of the studied quantities being the heat resistance of the steel. This parameter is important for the performance of such a test object. Regression equations are derived, which are analyzed using our own methodology. A complex connection between the heat resistance and the phase composition has been established, with the help of which the adequacy of the used approach is substantiated.
