Procedure for the manufacture of an alloy steel with nitrogen with a high wear resistance with the following composition (in mass -%): C: 0, 8-2, 5% N: 0, 03-0, 75% If: 0, 15-1, 8% Mn:: 51, 0% P: 0, 03% S - 0, 05% Cr: 5, 0-11, 5% Mo: 0, 5 ¿6, 0% V : - 4, 0% Nb: - 4, 0% W: 3, 5% O2: 0.005% with up to 0.05% of B, up to 0.5% of Ti, up to 0.5% of Zr, up to 0.25% of Al as optional alloy particles and as iron and the usual impurities, where a corresponding wear factor Sv of the sums of its weighted content of Cr, Mo, V, Nb and W, meets the following conditions: 0.55 Sv 3.42 with Sv = (ACr / 9, 33) + (AMo / 17, 22) + (Av / 3, 92) + (ANb / 7 , 15) + (Aw / 14, 14), ACr: the content of Cr in% of mass, AMo: the content of Mo in% of mass, Av: the content of V in% of mass, ANb: the content of Nb in% of mass, AW: the content of W in% of mass, and where the ratio of silicon - nitrogen VSiN meets with the following conditions: 0, 21 - VSiN 3, 31 with VSiN = ASi + 2AN ASi: the content of Si in% of mass, AN: the content of N in% of mass, which covers the following work steps : - the dispersion compaction of the steel casting with the use of nitrogen as a dispersing gas. - the hot forming of the steel after compaction by dispersion of the laundry with a starting temperature of up to 1150 ° C, - the cooling of the hot-formed steel, - the reheating of the cooled steel at an austenitization temperature of 1075 ° C to 1225 ° C, - the water cooling of the reheated steel and - the normalization of the water-cooled steel at a temperature of 150ºC-625ºC.
