Abstract

LIGAS DURAS DE COMPOSIçãO ENXUTA, apresentando uma composição de elementos de liga que consistem, em porcentagem em massa, de Carbono entre 0,5 e 2,0; Cromo entre 1,0 e 10,0; Tungstênio equivalente, dado pela relação 2Mo+W, entre 7,0 e 14,0; Nióbio entre 0,5 e 3,5, podendo o Nióbio ser parcial ou totalmente substituído por Vanádio, em uma relação de 2% de Nióbio para cada 1% de Vanádio; Vanádio entre 0,5 e 3,5, podendo o Vanádio ser parcial ou totalmente substituído por Nióbio, em uma relação de 2% de Nióbio para cada 1% de Vanádio; Cobalto menor que 8, o restante substancialmente de Ferro e impurezas inevitáveis ao processo de elaboração. Para refino dos carbonetos, o aço da presente invenção pode possuir, opcionalmente, teores de Nitrogênio controlados, abaixo de 0,030 e adição de Cério ou outros elementos terras em teores entre 0,005 e 0,020. Para o mesmo fim, Silício e Alumínio podem, opcionalmente, ser adicionados, em teores entre 0,5 e 3,0% para ambos.
