          \u00a0O 17-7PH \u00e9 um a\u00e7o inoxid\u00e1vel endurecido com elevada resist\u00eancia e dureza, resist\u00eancia \u00e0 fadiga, boa resist\u00eancia \u00e0 corros\u00e3o e forjamento por matriz. Ap\u00f3s tratamento com solu\u00e7\u00e3o s\u00f3lida, \u00e9 uma estrutura de austenite inst\u00e1vel com boa tenacidade pl\u00e1stica e processabilidade. Ap\u00f3s o ajuste, a precipita\u00e7\u00e3o de austenite da composi\u00e7\u00e3o de fenol de carboneto muda. Ap\u00f3s o tratamento de transforma\u00e7\u00e3o da martensite, a maioria das estruturas s\u00e3o transformadas em martensite temperada de baixo teor de carbono com boa tenacidade. Este estado \u00e9 o estado de utiliza\u00e7\u00e3o do a\u00e7o e tem boas propriedades mec\u00e2nicas a m\u00e9dia temperatura. A resist\u00eancia \u00e0 corros\u00e3o \u00e9 melhor do que a do a\u00e7o inoxid\u00e1vel martens\u00edtico em geral.<\/span><\/p>\n
