Abstract : Data on the influence of heat mechanical treatment on the abrasive wear resistance and other mechanical properties of some structural steels is presented. All steels were subjected to high temperature heat mechanical treatment: heating to a temperature above the maximum critical point; rolling with reductions of 15, 30, and 45 percent; annealing; and tempering at temperatures of 100, 200, 400, and 600 degrees centigrade. Steel 40KhNMA was subjected to low temperature heat mechanical treatment: heating above the maximum critical point to austenitic state, recooling to temperatures of 480 to 520 degrees centigrade in the intermediate stability region with a prolonged incubation period, and rolling, annealing and tempering as the other steels. The optimal abrasive wear resistance of the steels studied is basically determined by the preliminary degree of plastic deformation of austenite and the tempering temperature after annealing.
