Yeltsin, 19 Mira st., Ekaterinburg, 620002, Russian Federation 2 Institute of Metallurgy, Ural Branch of Russian Academy of Sciences, 101 Amundsen st., Yekaterinburg, 620016, Russian Federation Abstract Influence of different type heat treatment including high temperature quenching on wear resistance and was investigated. Analysis of the residual austenite contents influence on wear resistance was also made. It was determined that residual austenite formed after high temperature quenching (1100-1170°С) was metastable and had tendency to transform into carbon containing martensite of deformation. This allowed steels to have maximum wear resistance because of providing high abilities to friction hardening of the work place of the sample. It investigated the effect of tempering temperature on the phase composition and structure. It was determined the optimum regime of thermal processing of steel. This regime (high temperature quenching 1100- 1170°С) provides high wear resistance and structural strength.
