Purpose of work - to give recommendation in relation to the choice of the rational modes of heat treatment, and also to composition steels and cast-irons, for providing of optimum com-plex of mechanical and operating properties. Research methods - metallography, test on an abrasive and shock abrasive wear; mathe-matical treatment of results. It is set that the mode of heat treatment of chrome-manganese cast-irons of 220Х2Г(2-6) must get out taking into account the weekend of chemical and phase compositions. It is rotined that the electronegativeness is instrumental in higher maximum solubility of carbon in alpha - to the gland as compared to nitrogen. Temperature-temporal it is possible the parameters of normalization in wide limits to regulate phase composition, kinetics of deformation martensite transformation and to manage properties of wearproof cast-irons. Bor, as an alloying element, is the stabilizator of austenite in wearproof high-carbon al-loys on Fe-C-Cr-Mn to basis. Influence of chemical composition of Х52…80 steels on their mechanical properties. Industry of the use - machine-building and metallurgical enterprises of Ukraine.
