Abstract

resumo novas classes de aços não inoxidáveis com elevada resistência e alta ductilidade a presente descrição está direcionada às formulações e aos métodos para proporcionar ligas de aços não inoxidáveis tendo uma elevada resistência relativa e ductilidade. as ligas podem ser fornecidas em lâminas ou formas pressionadas e caracterizadas pelas suas químicas de liga particulares e morfologia tamanho de grão cristalino identificável. as ligas são tais que incluem fases de fixação de boreto. no que é chamado de aço de classe 1, as ligas indicam resistência à tração de 630 mpa a 1.100 mpa e alongamentos de 10 – 40 %. o aço de classe 2 indica uma resistência à tração de 875 mpa a 1590 mpa e alongamentos de 5 – 30 %. o aço de classe 3 indica uma resistência à tração de 1.000 mpa e 1.750 mpa e alongamentos de 0,5 – 15 %.
