Abstract

"TUBO DE AçO DE LIGA DE BAIXO TEOR DE CARBONO, VASO DE PRESSãO DE INFLADOR DE GáS ARMAZENADO, INFLADOR DE AIRBAG AUTOMOTIVO, E MéTODO DE FABRICAçãO DE UM PEDAçO DE TUBULAçãO DE AçO". Trata-se de um tubo de aço de liga de baixo teor de carbono e um método de fabricação do mesmo em que a tubo de aço consiste essencialmente, em peso: de aproximadamente 0,06% a aproximadamente 0,18% de carbono; de aproximadamente 0,5% a aproximadamente 1,5% de manganês; de aproximadamente 0,1% a aproximadamente 0,5% de silício; até aproximadamente 0,015% de enxofre; até aproximadamente 0,025% de fósforo; até aproximadamente 0,50% de níquel; de aproximadamente 0,1% a aproximadamente 1,0% de cromo; de aproximadamente 0,1% a aproximadamente 1,0% de molibdênio; de aproximadamente 0,01% a aproximadamente 0,10% de vanádio; de aproximadamente 0,01% a aproximadamente 0,10% de titânio; de aproximadamente 0,05% a aproximadamente 0,35% de cobre; de aproximadamente 0,010% a aproximadamente 0,050% de alumínio; até aproximadamente 0,050% de nióbio; até aproximadamente 0,15% de elementos residuais; e ferro e impurezas incidentais como o restante. O aço tem um limite de resistência à tração de pelo menos aproximadamente 145 ksi e exibe um comportamento dúctil a temperaturas tão baixas quanto 60<198>C.
