Abstract

"MéTODO PARA FABRICAçãO DE PARAFUSO DE ALTA RESISTêNCIA, EXCELENTE EM RESISTêNCIA à FRATURA RETARDADA E A ALìVIO DE TENSõES MEDIANTE FLUêNCIA". Divulga-se um parafuso de alta resistência tendo resistência à fratura retardada e resistência á relaxação de esforço excelentes além de um limite de resistência à tração de 1200 N/mm^ 2^ ou superior. Um aço para o parafuso de alta resistência inclui C: 0,50 até 1,0% em massa (daqui em diante, referido simplesmente como "%"), Si: 0,5% ou menos (não incluindo 0%), Mn: 0,2% até 1%, P: 0,03% ou menos (incluindo 0%) e S: 0,03% ou menos (incluindo 0%). O aço tem uma estrutura de ferrita proeutetóide, uma estrutura de cementita proeutetóide, uma estrutura de bainita e uma estrutura de martensita de menos que 20% no total e uma estrutura de perlita como saldo. O parafuso de alta resistência é produzido trefilando severamente o aço para obter um arame de aço, modelando o arame de aço na forma de um parafuso, por meio de recalque axial a frio, e submetendo o arame de aço conformado a um tratamento de azulagem a uma temperatura dentro da faixa de 100 até 400<198>C.
