1. Introdu\u00e7\u00e3o aos materiais 254SMO<\/span><\/strong><\/p>\n

\u00a0 \u00a0 \u00a0 O 254SMO \u00e9 um a\u00e7o inoxid\u00e1vel austen\u00edtico. Devido ao seu elevado teor de molibd\u00e9nio, tem uma resist\u00eancia extremamente elevada \u00e0 corros\u00e3o em po\u00e7os e em fendas. Estes tipos de a\u00e7o inoxid\u00e1vel s\u00e3o desenvolvidos e desenvolvidos para utiliza\u00e7\u00e3o em ambientes que cont\u00eam halogenetos, como a \u00e1gua do mar. O 254SMO tamb\u00e9m tem uma boa resist\u00eancia \u00e0 corros\u00e3o uniforme. Especialmente entre os \u00e1cidos que cont\u00eam halogenetos, este a\u00e7o \u00e9 melhor do que o a\u00e7o inoxid\u00e1vel comum.<\/span><\/p>\n

4. Resist\u00eancia \u00e0 corros\u00e3o do 254SMO<\/span><\/strong><\/p>\n

\u00a0 \u00a0 \u00a0 O 254SMO tamb\u00e9m tem boa resist\u00eancia \u00e0 corros\u00e3o uniforme. Especialmente entre os \u00e1cidos que cont\u00eam halogenetos, este a\u00e7o \u00e9 melhor do que o a\u00e7o inoxid\u00e1vel comum. O seu teor em C \u00e9 <0,03%, pelo que \u00e9 designado por a\u00e7o inoxid\u00e1vel austen\u00edtico puro (<0,01% \u00e9 tamb\u00e9m designado por a\u00e7o inoxid\u00e1vel super austen\u00edtico).<\/span><\/p>\n

\u00a0 \u00a0 \u00a0 O a\u00e7o inoxid\u00e1vel super \u00e9 um a\u00e7o inoxid\u00e1vel especial. Antes de mais, \u00e9 diferente do a\u00e7o inoxid\u00e1vel normal em termos de composi\u00e7\u00e3o qu\u00edmica. Refere-se a um a\u00e7o inoxid\u00e1vel de alta liga com elevado teor de n\u00edquel, cr\u00f3mio e molibd\u00e9nio. Entre eles, o mais famoso \u00e9 o 254SMo que cont\u00e9m 6%Mo. Este tipo de a\u00e7o tem uma resist\u00eancia \u00e0 corros\u00e3o local muito boa. Tem uma boa resist\u00eancia \u00e0 corros\u00e3o por pite (PI \u226540) e uma boa resist\u00eancia \u00e0 corros\u00e3o sob tens\u00e3o em condi\u00e7\u00f5es de \u00e1gua do mar, insufla\u00e7\u00e3o, folgas e eros\u00e3o a baixa velocidade. \u00c9 um substituto para ligas \u00e0 base de Ni e ligas de tit\u00e2nio. Em segundo lugar, em termos de resist\u00eancia a altas temperaturas ou \u00e0 corros\u00e3o, tem melhor resist\u00eancia a altas temperaturas ou \u00e0 corros\u00e3o, e \u00e9 insubstitu\u00edvel ao a\u00e7o inoxid\u00e1vel 304. Al\u00e9m disso, em termos de classifica\u00e7\u00e3o do a\u00e7o inoxid\u00e1vel, a estrutura metalogr\u00e1fica do a\u00e7o inoxid\u00e1vel especial \u00e9 uma estrutura metalogr\u00e1fica de austenite est\u00e1vel.<\/span><\/p>\n
