Research objects are non-destructive evaluation methods of structural steels composition during long-term operation. Research methods and equipment: method of mathematic simulation, method of artificial neural networks and microscopic survey of material structure.. As a result of work, steelwork mechanical characteristics correlation with microstructural state in power engineering that change during operation were determined for information parameters of their non-destructive testing as well as that existing algorithms of steelwork safe operation residual lifetime taking into consideration degradation level of their physical and mechanical characteristics (yield stress/fatigue value, impact strength), change of size-shape factors (wall thickness, eccentricity) and results of criticality evaluation of faults like integrity damage.
