This paper deals with changes in mechanical and structural properties of Steel T23 during long-time annealing at high temperatures. The research is focused on the degradation of the base material (steel T23), where the samples of steel, after the initial heat treatment, were annealed at temperatures of 600, 650 and 700 °C for 10 to 10 000 hours in a furnace with air atmosphere. This contribution summarizes the experimental results of mechanical and structural measurements and gives the relations between them.
