Wear resistance of structural steels 20 and 45 and high-nitrogen steel DDT68 during dry friction under different load conditions was studied. With an increase in slip to 20% at a load of 550 N the wear intensity increases 1.41 times for high-nitrogen steel and 1.54 times for structural steel. During sliding the surface fractures by tearing of the material under intense thermal setting, which affects the formation of secondary structures with increased oxygen concentration. With the reliability approximation of R 2 = 0.87 – 0.99 logarithmic and polynomial equations which describe the wear intensity in the conditions of slip and loading changes for the studied steels are obtained. After hydrogen charging the wear products have a significantly more complex textured microrelief with strips and larger sizes: ≥ 350 μm (P = 250N), 600 – 1000 μm (P = 400N), 800 – 1300 μm (P = 600N).
