Abstract

UM AçO AUSTENìTICO E UM PRODUTO DE AçO. Aços mcx austeníticos de alta liga, que são extra-resistentes à corrosão por pites e por frestas em soluções fortemente concentradas contendo cloreto, possuem uma tendência para a macro-segregação de Mo, na solidificação do fundido. Este problema é resolvido por um aço inox de super austenita possuindo a seguinte composição, em % por peso: máx 0,03 de C, máx 0,5 de Si, máx 6 de Mn, 28-30 de Cr, 21-24 de Ni, 4-6% de (No + W/2), o conteúdo de W sendo máx 0,7, 0,5-1,1 de N, máx 1,0 de Cu, ferro como balanço e impurezas originadas da produção do ferro dentro das quantidades normais.
