description: At the moment, steels of the X80 strength category are actively used, since they satisfy most of the requirements of customers, and pipes of higher strength categories are much more difficult to manufacture. The aim of the work is to analyze the factors affecting the fracture toughness of pipe steels and the relationship between fracture toughness and the structure and results of mechanical tests based on scientific and technical literature. During the performance of the work the following tasks were solved: 1) Analysis of literature containing material on the relationship between me-chanical and viscous properties and the structure of steels; 2) Study methods of controlling mechanical properties by changing the structure by optimizing the parameters of thermomechanical processing; 3) Familiarization with the application of digital technologies as a method of steel structure control. As a result, the relationship between thermo-mechanical treatment parame-ters, chemical composition and the final structure of steel was analyzed.
