Introducci\u00f3n al acero Duplex 2205<\/h2>\n
\"Tuber\u00eda<\/a>
Tuber\u00eda d\u00faplex 2205<\/figcaption><\/figure>\n

Desde el descubrimiento de la organizaci\u00f3n de dos fases, el acero inoxidable d\u00faplex que hizo\u00a0tubos de acero inoxidable d\u00faplex<\/a> (denominado \"acero d\u00faplex\") se ha desarrollado durante tres generaciones:<\/p>\n

La primera generaci\u00f3n de DSS (acero inoxidable d\u00faplex) est\u00e1 representada por el acero 3RE60 desarrollado en Suecia a mediados de la d\u00e9cada de 1960;<\/p>\n

El DSS de segunda generaci\u00f3n est\u00e1 representado por 2205 desarrollado por Suecia despu\u00e9s de la d\u00e9cada de 1970, y el PREN es 32 ~ 39;<\/p>\n

El DSS de 3\u00aa generaci\u00f3n es un acero inoxidable superd\u00faplex (SDSS) de un contenido de carbono ultrabajo, alto molibdeno<\/a> y alto contenido en nitr\u00f3geno que se desarroll\u00f3 a finales de los a\u00f1os ochenta. Sus grados representativos son 2507, 2906, 2707, etc. El valor PRE es grande hoy en d\u00eda, hablamos principalmente del mayor y m\u00e1s com\u00fan acero d\u00faplex 2205 (los grados internacionales son UNS S31803 y UNS S32205). Generalmente, el acero d\u00faplex se refiere al grado 2205 sin instrucciones especiales.<\/p>\n

Ventajas del acero d\u00faplex bif\u00e1sico austenita + ferrita<\/h2>\n

\"tubos<\/a><\/p>\n

El acero d\u00faplex est\u00e1 formado a base de acero inoxidable austen\u00edtico 18-8, que aumenta el contenido de Cr o a\u00f1ade otros elementos de ferrita, de modo que el acero tiene estructura bif\u00e1sica de austenita y ferrita, y ahorra n\u00edquel.<\/p>\n

La relaci\u00f3n te\u00f3rica es 1: 1, que es aproximadamente 50%. Generalmente, una determinada fase es 40 ~ 60%.<\/p>\n

Bajo estr\u00e9s bajo, el acero de doble fase que contiene cromo tiene buena resistencia a la corrosi\u00f3n por estr\u00e9s por cloruro y buena resistencia a la corrosi\u00f3n por picadura. En general, la resistencia a la corrosi\u00f3n por picaduras y grietas de los aceros d\u00faplex supera los 316L. Debido a la excelente resistencia a la corrosi\u00f3n y fuerza requerida. Seg\u00fan las estad\u00edsticas, la cantidad de 2205 se ha incrementado al menos 15 veces en los \u00faltimos diez a\u00f1os.<\/p>\n

Las propiedades mec\u00e1nicas completas son buenas, con alta resistencia y resistencia a la fatiga, y el l\u00edmite el\u00e1stico es el doble que el del acero inoxidable austen\u00edtico 18-8. Por lo tanto, el grosor del material se puede reducir en dise\u00f1o.<\/p>","protected":false},"featured_media":5214,"template":"","categories":[186],"tags":[],"class_list":["post-5233","blog","type-blog","status-publish","has-post-thumbnail","hentry","category-stainless-steel-knowledge"],"yoast_head":"\nThe Advantages of Duplex 2205 Pipe - Stainless Steel Pipe and Fittings | KAYSUNS<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.kaysuns.com\/es\/blog\/ventajas-del-tubo-duplex-2205\/\" \/>\n<meta property=\"og:locale\" content=\"es_ES\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"The Advantages of Duplex 2205 Pipe - Stainless Steel Pipe and Fittings | KAYSUNS\" \/>\n<meta property=\"og:description\" content=\"Introduction for\u00a0Duplex 2205 Steel Since the discovery of the two-phase organization, the duplex stainless steel which made\u00a0duplex stainless steel pipes (referred to as “duplex steel”) has been developed for three generations: The first generation DSS (duplex stainless steel) is represented by 3RE60 steel developed in Sweden in the mid-1960s;
