Abstract

"AçO PARA PEçAS MECáNICAS, PROCESSO DE FABRICAçãO DE UMA PEçA MECáNICA E PEçA MECáNICA DE AçO" A presente invenção refere-se a um aço para peças mecânicas, caracterizado pelo fato de sua composição ser, em porcentagens ponderais: -0,19%= C = 0,25%; -1,1% = Mn =1,5%; -08% = Si = 1 2%; -0,01% = S = 0,09%;-traços = P = 0,025%; - traços = Ni = 0,25%; - 1% = Cr = 1,4%; - 0,10% = Mo =0,25%; - traços = Cu = 0,30%; - 0,010% = AI = 0045%; - 0,01 0% = Nb = 0,045%; -0,0130% = N = 0,0300%; - opcionalmente traços = Bi = 0,10% e/ou traços = Pb =0,12% e/ou traços = Te = 0,015% e/ou traços = Se = 0,030% e/ou traços = Ca =0,0050%; sendo que o restante é constituído por ferro e impurezas que resultam da elaboração, e a composição química é ajustada para que os valores médios J3m, J11m, J15m, e J25m de cinco ensaios Jominy sejam tais que: a = ? J11m - J3m X 14/22 -J25m X 8/22 ? = 2,5 HRC; e B = J3m - J15m = 9 HRC. Processo de fabricação de uma peça mecânica que utiliza este aço e peça mecânica assim obtida."STEEL FOR MECHANICAL PARTS, MANUFACTURING PROCESS OF A MECHANICAL PART AND MECHANICAL STEEL PART" The present invention relates to a steel for mechanical parts, characterized in that its composition is, in weight percentages: -0.19% = C = 0.25%; -1.1% = Mn = 1.5%; -08% = Si = 12%; -0.01% = S = 0.09% - dashes = P = 0.025%; - dashes = Ni = 0.25%; - 1% = Cr = 1.4%; - 0.10% = Mo = 0.25%; - dashes = Cu = 0.30%; - 0.010% = AI = 0045%; - 0.010% = Nb = 0.045%; -0.0130% = N = 0.0300%; - optionally dashes = Bi = 0,10% and / or dashes = Pb = 0,12% and / or dashes = Te = 0,015% and / or dashes = Se = 0,030% and / or dashes = Ca = 0,0050% ; The remainder being iron and impurities resulting from the elaboration, and the chemical composition is adjusted so that the average values J3m, J11m, J15m, and J25m of five Jominy tests are such that: a =? J11m - J3m X 14/22 -J25m X 8/22? = 2.5 HRC; and B = J3m - J15m = 9 HRC. Process of manufacturing a mechanical part using this steel and mechanical part thus obtained.
