Abstract

resumo patente de invenção: "material de aço que tem excelente resistência à corrosão atmosférica". a presente invenção refere-se a um aço resistente à corrosão atmosférica que é adequado como um material de aço estrutural que é usado em principalmente em estruturas ao ar livre tal como uma ponte, particularmente sob um ambiente de temperatura elevada onde uma seca ou estação de seca com pouca chuva está presente. um material de aço que contém quantidades específicas de c, si, mn, p, s, al, cu, nb, sn, que satisfaz a relação (1) e/ou a relação (2) e satisfaz a relação (3) e que contém, conforme necessário, um ou mais selecionado dentre ni, cr, mo, w, co, sb, ti, v, zr, b, rem, ca e mg, o saldo sendo fe e impurezas inevitáveis. (cu-0,01) x (sn-0,005) x (nb-0,005) x 104 = 0,08 (1), (cu-0,01) x (ni-0,01) x (cr-0,01) x 50 = 0,08 (2), (cu+10xsn) / (2xni+0,5xsi) < 10 (3) [em que os símbolos de elementos representam o teor (% em massa) dos mesmos respectivamente, sendo que o teor de um elemento que não está contido é tomado como zero].
