Abstract

<B>"AçO INOXIDáVEL AUSTENìTICO RESISTENTE AO CALOR"<D>. A invenção se refere a um aço inoxidável austenítico com alta resistência sob elevadas temperaturas, uma boa resistência à oxidação causada por vapor e uma boa resistência à corrosão por combustão lateral, com uma suficiente estabilidade estrutural. O aço inoxidável austenítico é adequado para uso em caldeiras que operam sob altas temperaturas. O aço consiste de (por peso): 0,04 a 0,10% de carbono (C), não mais que 0,4% de silício (Si), não mais que 0,6% de manganês (Mn), 20 a 27% de cromo (Cr), 22 a 32% de níquel (Ni), não mais que 0,5% de molibdênio (Mo), 0,20 a 0,60% de nióbio (Nb), 0,4 a 4,0% de tungstênio (W), 0,10 a 0,30% de nitrogênio (N), 0,002 a 0,008% de boro (B), 0,003 a 0,05% de alumínio (Al), pelo menos um dos elementos magnésio e cálcio em quantidades menores que 0,010% de magnésio (Mg) e menos que 0,010% de cálcio (Ca), o balanço sendo ferro e impurezas inevitáveis.
