Abstract

PROCESSO PARA REDUZIR A NOCIVIDADE DAS VEIAS SEGREGADAS DE UM AçO, AçO DE ALTA RESISTêNCIA MECáNICA E ALTA RESISTêNCIA AO DESGASTE, PROCESSO PARA FABRICAR UMA PEçA DE AçO E PEçA DE AçO A presente invenção refere-se a um processo para reduzir as veias segregadas de um aço de alta resistência mecânica e de alta resistência ao desgaste cuja composição compreende em peso: 0,30% <243> C <243>1,42%; 0,05% <243>Si <243>1,5%; Mn <243>1,95%; Ni <243>2,9%; 1,1% <243>Cr <243>7,9%; 0,61% <243>Mo <243>44%; eventualmente V <243>1,45% Nb <243>1,45%, Ta <243>1,45%, e V + Nb/2 + Ta/4 <243>1,45%; menos de 0,1% de boro, de 0,19% de (S + Se/2 + Te/4), de 0,01% de cálcio, de 0,5% de terras raras, de 1% de alumínio e de 1% de cobre; sendo que o restante é ferro e impurezas que resultam da elaboração. A composição satisfaz ainda a: 800 <243>D <243>1.150 com D = 540 (C)¬ 0,20¬ + 245 (Mo + 3V + 1,5 Nb + 0,75 Ta)¬ 0,30¬ + 125 Cr¬ 0,20¬ + 15,8 Mn + 7,4 Ni + 18 Si. De acordo com o processo, substitui-se todo ou parte do molibdeno por uma proporção dupla de tungstênio de modo que W > 0,21% e ajusta-se Ti, Zr e C para que, depois do ajuste, Ti + Zr/2 = 0,2 W, (Ti + Zr/2) x C = 0,07, Ti + Zr/2 = 1,49% e D fique inalterado com uma tolerância de 5%. A presente invenção refere-se também ao aço obtido e processo de fabricação de uma peça de aço.
