Manufacturing die steels with ferritic initial basis for work in austenite state is determined by the provisions of temperature to austenite transformation as heating tool during operation should ensure passage of this transformation to the next long work in austenite state. Therefore, the chemical composition of the steel should be selected so that the temperature to austenite conversion set was located below the instrument operating temperature. At operating temperatures up to 600-650 °C is satisfactory tool life in many cases provided using conventional die steels based on ferritne solid solution strengthening from carbide. At operating temperatures over 650 °C, even the most heat-resistant steel intensively rozmitsnyuyutsya that is the main reason for the rapid release of the tool down. Resistance Tool for hot deformation can be greatly enhanced by using a new class of die steel with adjustable austenitic transformation during operation (steel La Rapet). Such steel in the initial state are ferritic base (which provides satisfactory adaptability during machining), and when heated to operating temperature from ferritne to austenitne transformation and subsequently retained austenitic structure period of high exploitation tool.
