Abstract: The wear resistance of DI37-VI and EK80-VI steel is studied using a device for investigating friction. A sample made of high-carbon chromium-vanadium steel relative to pellets of MS221, VK3M, and VK6OM hard alloys on this device carries out reciprocating motion at a rate of 0.1 m/s. The base friction path is 50 km and the average temperatures of the samples are 100, 140, and 190$^\circ$C. The effect of an average temperature of samples on the wear resistance of DI37-VI and EK80-VI steel is described.

Keywords: wear resistance, dry friction, specific load, chromium, vanadium, carbides.
