Abstract

"AÇO BAINÍTICO PARA MOLDES", apresentando uma composição de elementos de liga que consistem, em porcentagem,em massa, de Carbono entre 0,05 e 1,0; Manganês entre 0,5 e 3,0; Fόsforo, Bora, Titânio e Vanádio dados pela relação NU = [%Ti + %P + 10%B + (%V - 0,10)], estando os valores de NU entre 0,02 e 0,30, sendo o titánio sempre acima de 0,005, o bora sempre abaixo de 0,010 e o vanádio podendo ser parcial ou totalmente substituído por niόbio, numa proporção de duas partes em massa em niόbio para uma parte de vanádio; Níquel, Molibdênio e Cromo dados pela relação G = [0,13 %Ni + 0,60 %Mo + 0,26 %Cr], estando os valores de G acima de 0,10 e abaixo de 1,0; Níquel acima de 0,1; Molibdênio entre 0,07 a 0,27; Vanádio entre 0,1 a 0,15; Enxofre ate 0,10; Silício entre 0,05 e 3,0; Nitrogênio abaixo de 0,10; Calcio em teores ate 0,02; Alumínio abaixo de 0,5; Cr abaixo de 1,5; Silício entre 0,05 e 3,0; Fόsforo abaixo de 0,075 e o restante substancialmente de Ferro e impurezas inevitáveis ao processo de elaboração; para sua produção a dureza final pode ser obtida por resfriamento ao ar calmo, diretamente apόs conformação a quente ou por aquecimento prévio em forno, mesmo em blocos de secção até 1000 mm; os valores de dureza, na escala Vickers, são definidos pela equação: HV = (450 ± 140) %C + (210 ± 45), para valores entre 280 e 450 HV (30 a 45 HRC); para aplicações de alta tenacidade, o aço da presente invenção pode, ainda, ser produzido com resfriamento rápido, de temperaturas acima de 900°C, em meios de água e όleo.
