The possibility of using computational and experimental methods of strain and fracture mechanics for describing degradation of mechanical properties of steels under conditions of pyrolysis is demonstrated. Experimental and theoretical temperature dependences of the ultimate strength of 10Kh23N18 steel which are characterized by a high degree of correlation are obtained. It is revealed that it is necessary to use correlation coefficients in the equations for calculating the ultimate strength depending on the service time to increase the accuracy of forecasting variations in the mechanical characteristics of steel under operating conditions.
