| abstract | The invention relates to metallurgy, in particular to steel, which can be used to make dies with a diameter of up to 225 mm, a height of 300 mm hot deformation, having a heating surface up to 470 ° C, for pressing taper-like parts of high strength. become. The proposed steel contains, in May,%: 0.44-0.65 carbon, 0.17- 0.37 silicon, 0.7-1.0 manganese, 0.7-1.2 chromium, 0.9-1, 5 nickel, 0.25–0.40 molybdenum, 0.20–0.34 copper, 0.40–0.60 tantalum, 0.16–0.22 niobium, 0.10–0.17 cerium carbides, 0 , 07- 0.14 tantalum disilicides, 1.22-1.95 rhenium, 0.04-0.06 thallium, 0.08-0.14 ytterbium, 0.05- 0.11 sodium, iron - the rest, with provided that the total content of itterium and thallium should be 0.11-0.18, and the ratio of the total content of molybdenum, tantalum, niobium, rhenium to carbon content should be 3.75-6.29. Mechanical and technological properties of the proposed steel: high levels at a test temperature of 470 ° C hardness, crack initiation work, yield strength under compression, as well as high levels after the action of cyclic compression loads at a temperature of 470 ° C thermal fatigue, relaxation resistance, wear resistance exceeds the mechanical and technological properties of previously known tool steels. 2 hp f-ly.
