Abstract
resumo patente de invenção: "aço para mola e mola". a presente invenção refere-se a um aço para molas que é finalmente conformado em uma mola, fazendo-se uso, no máximo, do efeito de resistência ao amolecimento na têmpera devido aos elementos de ligação, enquanto suprime a formação de inclusões duras de sio2 e a geração de descarburação, que pode provocar a deterioração das características de fadiga da mola. o aço para molas é caracterizado por compreender, em % em massa, c: 0,50 a 0,70%, si: 1,00 a 5,00%, mn: 0,30 a 2,00%, p: 0,0002 a 0,0500%, s: 0,0002 a 0,0500%, cr: 0,10 a 3,50%, al: 0,0005 a 0,0500%, e n: 0,0020 a 0,0100%, com o saldo sendo fe e as inevitáveis impurezas, onde o valor h definido pela equação (a) a seguir é 160 ou mais, e o valor c definido pela equação (b) a seguir é 3,25 ou menos: h = 33,6[c] + 10,0[si] + 5,95[mn] + 11,1[cr] + 90,0 (a), e c = [si]/[mn] (b).
