of vanadium, maximally 0,05 % of titan, maximally 0,045% of the total contents of aluminium in steel, maximally 0,015% of phosphor, maximally 0,015% of sulphur.
The advantages of the steel in comparison with the actual technical situation include reaching of improved mechanical characteristics, where the strength limit Rm is 950 MPa up to 1300 MPa, the yield limit Rp0,2 is minimally 750 MPa up to 915 MPa, impact value KCV is minimally 20 J/cm2, hardness 290 HB up to 420 HB and ductility minimally 10%.
Descri tion The sample of the technical solution according to the utility model includes steel, which includes iron with weight % of 0,140% of w0 01/36698 carbon, 0,80% of manganese, 0,34% of silicon, I,76% of chrome, 0,471% of molybdenum, 2,63% of nickel, 0,087% of vanadium, 0,045 of titan, maximally 0,042% of the total contents of aluminium in steel, maximally 0,014% of phosphor, 0,009% of sulphur.
This steel is characterised by the final strength limit (Rm) of 1147 MPa, the yield limit (Rp0,2) 91 S MPa, the impact value (KCV+20°) 26 J/cm2, hardness 338 HB, ductility (AS) 14,8%.
Industrial Aunlicability The technical solution can be advantageously used for railway and tram point crossing frog castings with high requirements on resistance against wearing. The steel is highly strenuous, it allow good-quality welding and machining of the crossing frogs.
