ABOUT OPTIMIZATION OF COMPOSITIONS HIGH-SPEED AND DIE STEELS Sobachkinа L.D. , Graduate student, e-mail: karpov43@list.ru Butygin V.B. , Ph.D. (Engineering), Professor, e-mail: karpov43@list.ru I.I. Polzunov Altai State Technical University, 46 Lenina avenue, Barnaul, Altai region, 656038, Russian Federation Abstract In this paper we describes the ways of doping tool steels by elements in the amount, allowing to increase the content of the hardening phase, hardness, hardenability, heat resistance. We consider the possibility of cheapening the cost of tool steels, by complex alloying less expensive elements. Examined steels is possible to use for the punching tools working in a temperature range from 300 to 650 °C. The steel 3M2H10V3K can be used to a temperature of 750 °C. Lower cost of these steels explained by the lower amount of alloying elements. Keywords heat treatment, alloying, heat resistance, hardness, phase composition, forging, carbides, quenching
