We studied carbon steels (from technical iron to Y8) and low-alloy steel 65G. The grades of these steels are regulated by GOST 8559-75. To create different structures in the studied steels, the samples were subjected to heat treatment. The processing modes were selected in such a way as to ensure the study of the effect on wear resistance of one structural parameter of steel with the relative stability of other parameters. The relationships between the parameters of the structure of heat-treated steels and their abrasive wear resistance are established. At all temperatures of the final tempering of hardened steel, there is a direct relationship between its structure parameters (the number of elements in a solid solution, the density of dislocations, the size of cementite particles and the intercementite distance) and wear resistance when sliding friction against loose abrasive particles. A computer program has been developed to select the chemical composition of the steel grade and methods of thermal hardening in order to ensure the required wear resistance.
