Purpose: Characteristics of functional properties of austenitic- based steels used for construction of boilers with supercritical and ultra-supercritical steam parameters. Design/methodology/approach: For selected austenitic steels in as-received state and after long-term annealing microstructural investigations were carried out with scanning and transmission electron microscope. Findings: Selected characteristics of structure and functional properties of materials to be used for critical elements in the pressure selection of power boilers were summarized in a single paper. Practical implications: The steel characteristics presented in this paper are used for assessment of structural changes and changes in strength properties of material o elements after long-term service under creep conditions. Originality/value: The presented results of the mechanical properties, structure and in the precipitation processes are applied to evaluation the condition of the elements in further industrial service.
