Ensuring reliable operation of dangerous objects during or beyond the source life is a very important task in the context of the current economic situation in the Ukrainian energy sector. For this purpose, continuous full-scale monitoring of the main and additional equipment state of power plants is carried out in accordance with the normative documents. Estimation of the current state of materials is carried out according to certain parameters. One of these parameters is the value of the mechanical properties. Determining the mechanical properties of structures materials by the results of uniaxial tension tests is not always possible as it requires, in most cases, the destruction of the structure, the availability of sufficient volume of material for the production of specimen and complex and expensive testing equipment. To avoid the aforementioned limitations, new indirect methods for determining the mechanical properties are developed. Among them \u2013 the small punch test. Today, a number of different methods have been developed for determining the mechanical properties of materials based on the results of small punch test. In this paper, a comparative analysis of the most common methods for determining the strength properties of steels by small punch test. The research was carried out using materials of different strength \u2013 steel 45, 10HN2MFA and 15\u04252NMFA. The deviation value was determined in the strength properties determining of these materials using different methods. It has been shown that the deviation of the strength properties of these materials, which is determined by small punch test using the most common techniques, from those obtained during the tensile test, exceeds 10%. The results will be used in further studies to improve the correlation dependencies in the determination of mechanical properties by small punch test.
