Ha habido tres generaciones de acero inoxidable d\u00faplex<\/strong><\/h2>\n\n\n\n

El desarrollo del acero inoxidable d\u00faplex tiene una historia de casi 90 a\u00f1os, y la fase de ferrita y la fase de austenita representan cada una el 50% de la estructura de acero inoxidable d\u00faplex.<\/p>\n\n\n\n

El desarrollo de los aceros inoxidables d\u00faplex comenz\u00f3 en la d\u00e9cada de 1930, en aquel momento para resolver el problema de la corrosi\u00f3n intergranular<\/a> de aceros inoxidables austen\u00edticos de alto contenido en carbono.<\/p>\n\n\n

El acero inoxidable d\u00faplex tiene ahora 3 generaciones:<\/strong><\/h3>\n\n\n\n

La primera generacion<\/strong>: representado por el acero inoxidable Tipo 329 desarrollado en los Estados Unidos en la d\u00e9cada de 1940, es ampliamente utilizado en tuber\u00edas de intercambiadores de calor de plantas de \u00e1cido n\u00edtrico.<\/p>\n\n\n\n

A mediados de la d\u00e9cada de 1960, Suecia desarroll\u00f3 el acero inoxidable d\u00faplex 3RE60 (00Cr18Ni5Mo3N) dise\u00f1ado para mejorar la resistencia a la fractura por corrosi\u00f3n por cloruro, pero debido a su alto contenido de carbono, generalmente se usa para fundici\u00f3n y forja.<\/p>\n\n\n\n

Segunda generaci\u00f3n<\/strong>: Desde la d\u00e9cada de 1970, con la popularizaci\u00f3n y el desarrollo de la tecnolog\u00eda de refinaci\u00f3n secundaria (AOD), la tecnolog\u00eda de refinaci\u00f3n al vac\u00edo (VOD) y la tecnolog\u00eda de colada continua, la producci\u00f3n de acero ultrabajo en carbono (w (C) \u22640.03%) es f\u00e1cil de realizar. , 00Cr22Ni5Mo3N es el representante del acero inoxidable d\u00faplex de segunda generaci\u00f3n.<\/p>\n\n\n\n

El grado de acero fue desarrollado con \u00e9xito por Suecia en la d\u00e9cada de 1970, con grado de material SAF2205<\/a>, y el grado correspondiente de EE. UU. es UNS S31803.<\/p>\n\n\n\n

La tercera generaci\u00f3n<\/strong>n: A finales de la d\u00e9cada de 1980, se desarroll\u00f3 con \u00e9xito el acero inoxidable d\u00faplex de tercera generaci\u00f3n, y las principales marcas son SAF2507<\/a>.<\/p>\n\n\n\n

Se caracteriza por su contenido ultrabajo en carbono, alto molibdeno<\/a>y alto en nitr\u00f3geno, tiene una excelente resistencia a la corrosi\u00f3n, y su PREN<\/a> el valor es mayor que 40.<\/p>\n\n\n\n

\n\n\n\n

En el siglo XXI, el acero inoxidable d\u00faplex tiene dos direcciones principales:<\/strong><\/h4>\n\n\n\n

Super Grado<\/strong>: por un lado, aumentar a\u00fan m\u00e1s el contenido de elementos de aleaci\u00f3n en el acero para obtener una mayor resistencia y una mejor resistencia a la corrosi\u00f3n, como SAF 2707 y SAF 3207 recientemente desarrollados por la empresa sueca SANDVIK. El valor PRE es superior a 45, lo que se denomina acero inoxidable superd\u00faplex (a menudo se expresa en HD).<\/p>\n\n\n\n

Grado econ\u00f3mico<\/strong>: Por otro lado, recurrimos al desarrollo de acero inoxidable d\u00faplex econ\u00f3mico con bajo contenido de n\u00edquel y sin molibdeno o solo una peque\u00f1a cantidad de molibdeno para reducir el costo y el precio de venta del acero inoxidable d\u00faplex y mejorar significativamente la trabajabilidad en caliente y la soldadura. de acero inoxidable d\u00faplex Para aumentar la ventaja competitiva del acero inoxidable d\u00faplex y otros tipos de acero inoxidable.<\/p>\n\n\n

La producci\u00f3n de acero inoxidable d\u00faplex en China aument\u00f3 de menos de 1.000 toneladas en 2001 a 180.000 toneladas en 2019. Proveedor de accesorios de tuber\u00eda de acero inoxidable d\u00faplex<\/a> Tambi\u00e9n est\u00e1 aumentando en especificaciones completas y modelos de planchas, tubos, perfiles y acero redondo d\u00faplex de acero inoxidable.<\/p>","protected":false},"featured_media":5255,"template":"","categories":[186],"tags":[],"class_list":["post-6222","blog","type-blog","status-publish","has-post-thumbnail","hentry","category-stainless-steel-knowledge"],"yoast_head":"\nA Brief History Of The Development Of Duplex Stainless Steel -
