Purpose of work - to give recommendation in rela-tion to the choice of the rational modes of heat treatment, and also composition of steels, for pro-viding of optimum complex of mechanical and operating properties. Research methods - metal-lographic, X-ray diffraction, dyurometrical; test on an abrasive wear; mathematical processing of results. The combined heat treatment is the effective method of adjusting of stability of austenite in relation to attitude toward deformation martensite transformation, and due to the lowered maintenance of manganese in new steels disintegration of austenite is considerably easier pro-vided with the receipt of ferritic-carbide mixture, than in steel of Gadfil'd. Possibility of grinding down of grain is conditioned these as a result of subsequent recrystallization, that it is extraordi-narily important for the poured details. At electroarc surfacing on carbon steel structural hetero-geneity in the area of alloy and high level of remaining tensions takes a place the band electrode of ЛН-02Х25Н22АГ4М2 , at what their most high level is observed in the three-layered stan-dards. Complex researches of influence of chemical composition, mode of the thermal strength-ening and structural parameters, are executed on mechanical properties of hot rolled plate which is normalized, from steels of S355 E36. Industry of the use - machine-building and metallurgical enterprises of Ukraine.
