Abstract
The prospects of production of special properties steels in the Russian and global metal market are estimated. The necessity of using new types of steels is substantiated. The prospects of introducing steels with special properties developed by PJSC “Magnitogorsk Iron and Steel Company” to the market are determined. Evaluation of measures for the production of large volumes of products showed that there is a problem of a significant increase in the time of manufacturing and delivery of output products to the consumer. As measures to ensure the modernization of the technological complex of the steel enterprise and reduce the time for steel production, the system of jet heat treatment of metal is proposed. According to the results of comparative analysis of the MAGSTRONG H500 and HARDOX 500 alloys used in mining equipment under conditions of increased wear, it was revealed that the proposed method of heat treatment allows one to achieve high wear resistance properties, with high coefficients of tensile strength and toughness.
