Abstract (en)
[origin: WO2013021009A1] The invention relates to steel for manufacturing carburized steel parts, characterized in that the composition thereof is: 0.1 wt % = C = 0.15 wt %; 0.8 wt % = Mn = 2 wt %; 1 wt % = Cr = 2.5 wt %; 0.2 wt % = Mo = 0.6 wt %; trace elements = Si = 0.35 wt %; trace elements = Ni = 0.7 wt %; trace elements = B = 0.005 wt %; trace elements = Ti = 0.1 wt %; trace elements = N = 0.01 wt % if 0.0005 wt % (5ppm) = B = 0.005 wt %, and trace elements = N = 0.02 wt % if trace elements = B = 0.0005 wt % (5ppm); - traces = Al = 0.1 wt %; trace elements = V = 0.3 wt %; trace elements = P = 0.025 wt %; trace elements = Cu = 1 wt %, preferably < 0.6 wt %; and trace elements = S = 0.1 wt %, the remainder being iron and impurities resulting from production. The invention also relates to a carburized steel part produced with said steel, and to the method for manufacturing same.
