The structure and characteristics of mechanical properties of low-carbon martensitic steel 12Kh2G2NMFB are studied after various kinds of thermal action. The laws of formation of the structural strength of the martensitic steel are studied as a function of the tempering temperature. The main mechanisms of crack propagation under static loading of the metal with a structure of lath martensite are described and the role of the temper brittleness of kind I is analyzed.
