Abstract (en)
[origin: WO2011124851A2] Mechanical part made of steel having high properties and process for manufacturing same. Mechanical part made of steel having high properties, characterized in that its composition, in percentages by weight, is: 0.05% = C = 0.25%; 1.2% = Mn = 2%; 1% = Cr = 2.5%; (830 - 270 C% - 90 Mn% - 70 Cr%) = 560; traces = Si = 1.5%; traces = Ni = 1%; traces = Mo = 0.5%; traces = Cu = 1%; traces = V = 0.3%; traces = Al = 0.1%; traces = B = 0.005%; traces = Ti = 0.03% traces = Nb = 0.06%; traces = S = 0.1%; traces = Ca = 0.006%; traces = Te = 0.03%; traces = Se = 0.05%; traces = Bi = 0.05%; traces = Pb = 0.1%; the balance being iron and impurities resulting from the smelting, and in that its structure is bainitic and contains at most 20% in total of martensite and/or proeutectoid fernite and/or perlite. Process for manufacturing a mechanical part having this composition.
