Abstract

"TUBO DE AçO PARA USO EM REFORçO DE AUTOMóVEL E MéTODO PARA SUA PRODUçãO". A invenção refere-se a um tubo de aço tendo uma composição que contém: 0,05 a 0,30% de C; 1,8 a 4,0% de Mn; Si; e Al é submetido a um processo de laminação para reduzir o diâmetro em que a taxa total de redução de diâmetro não é menos do que 20% e a temperatura na qual é acabado o processo de laminação para reduzir o diâmetro, não é maior do que 800<198>C, por meio do que a estrutura constituída de martensita e/ou bainita ou ainda de ferrita é obtida como um produto de transformação de <sym> deformada. Como resultado, um tubo de aço tendo resistência à tração de 1000 MPa ou mais e excelente propriedade de curvar em três pontos pode ser obtido. A composição do tubo de aço da presente invenção pode ainda incluir pelo menos um tipo de elemento selecionado do grupo consistindo em Cu, NI, Cr e Mo, ou pelo menos um tipo de elemento selecionado de um grupo consistindo em Nb, V, TI e B, ou pelo menos de um tipo selecionado do grupo consistindo em REM e Ca.
