Esta composici\u00f3n superior le confiere una resistencia excepcional a la corrosi\u00f3n por picaduras y en rendija en ambientes con cloruros, superando a los grados 316 y 317. La adici\u00f3n de nitr\u00f3geno no solo mejora la resistencia a la corrosi\u00f3n, sino que tambi\u00e9n aumenta la resistencia mec\u00e1nica, la resistencia a la tracci\u00f3n y el l\u00edmite el\u00e1stico. El AISI 317LMN es un material de alto rendimiento dise\u00f1ado para las condiciones m\u00e1s agresivas, incluyendo \u00e1cidos fuertes y ambientes salinos.<\/p>\n<p>Gracias a su formulaci\u00f3n avanzada con nitr\u00f3geno, el uso de AISI 317LMN es indispensable en plantas desalinizadoras y sistemas qu\u00edmicos severos.
