Abstract

"FIO DE AçO RESFRIADO BRUSCAMENTE E TEMPERADO COM CARACTERìSTICAS SUPERIORES DE FORJA A FRIO". é revelado um fio de aço resfriado a frio e temperado com características de forja a frio superiores, consistindo essencialmente em 0,1-0,5% em peso de C, 1,0% em peso ou menos de Si, 0,2-2,5% em peso de Mn, 0,03% em peso ou menos de P e 0,03% ou menos de S, com o restante sendo Fe e impurezas inevitáveis, que possui resistência a tensão de 700-1.300 Mpa e porcentagem de esferoidização de carbetos não inferior a 30%. Tal fio de aço resfriado bruscamente e temperado, que é submetido aos processos de resfriamento brusco e têmpera por aquecimento de indução de alta freq³ência em um período curto, sem um processo de recozimento esferoidizante que requeira período longo, possui características de forja iguais ou superiores àquelas do fio de aço recozido em esferoidização, aumentando assim a produtividade. Portanto, o fio de aço resfriado bruscamente e temperado é aplicável à fabricação de vários parafusos e eixos como peças para estruturas de máquinas que requerem altas resistências.
