Caracter\u00edsticas, clasificaci\u00f3n y desarrollo de tubos d\u00faplex de acero inoxidable<\/h2>\n

Desarrollo de acero inoxidable d\u00faplex<\/h3>\n

Los aceros inoxidables d\u00faplex se denominan "d\u00faplex" porque su microestructura metal\u00fargica consta de dos tipos de granos de ferrita y acero inoxidable austen\u00edtico. Cuando el acero inoxidable d\u00faplex se derrite, primero se solidifica en una estructura de ferrita completa cuando se solidifica desde el estado l\u00edquido. A medida que el material se enfr\u00eda a temperatura ambiente, aproximadamente la mitad de los granos de ferrita se transforman en granos de austenita. Como resultado, aproximadamente 50% de la microestructura era una fase de austenita y 50% era una fase de ferrita.<\/p>\n

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

La resistencia de los inoxidables d\u00faplex es aproximadamente el doble que la de los inoxidables austen\u00edticos o ferr\u00edticos convencionales. Por tanto, los dise\u00f1adores pueden reducir el grosor de las paredes en algunas aplicaciones. La resistencia a la corrosi\u00f3n del acero inoxidable depende principalmente de su composici\u00f3n qu\u00edmica. En la mayor\u00eda de las aplicaciones, los aceros inoxidables d\u00faplex muestran una elevada resistencia a la corrosi\u00f3n debido a su alto contenido en cromo, que es ventajoso en \u00e1cidos oxidantes, y contiene cantidades suficientes de molibdeno<\/a> y n\u00edquel para resistir \u00e1cidos moderadamente reductores. Corrosi\u00f3n del medio.<\/p>\n

Los aceros inoxidables d\u00faplex son resistentes a las picaduras de cloruros y la corrosi\u00f3n por grietas, seg\u00fan su contenido de cromo, molibdeno, tungsteno y nitr\u00f3geno. El contenido relativamente alto de cromo, molibdeno y nitr\u00f3geno de los aceros inoxidables d\u00faplex los hace muy resistentes a la corrosi\u00f3n por picaduras y grietas de los cloruros. Tienen una serie de diferentes propiedades de resistencia a la corrosi\u00f3n, ambas equivalentes a la resistencia a la corrosi\u00f3n del acero inoxidable 316, como el econ\u00f3mico acero inoxidable d\u00faplex 2101 \u00a9, y el equivalente al acero inoxidable de molibdeno 6%, como SAF 2507<\/a> \u00a9.<\/p>\n

Caracter\u00edsticas del acero inoxidable d\u00faplex<\/h3>\n

El acero inoxidable d\u00faplex tiene muy buena resistencia a agrietamiento por corrosi\u00f3n bajo tensi\u00f3n<\/a> (SCC). Esta propiedad se \"hereda\" de la parte ferrita. La resistencia de todos los inoxidables d\u00faplex al agrietamiento por corrosi\u00f3n bajo tensi\u00f3n por cloruros es significativamente mejor que la de los inoxidables austen\u00edticos de la serie 300. Los inoxidables austen\u00edticos est\u00e1ndar, como el 304 y el 316, pueden sufrir agrietamiento por corrosi\u00f3n bajo tensi\u00f3n en presencia de iones cloruro, aire h\u00famedo y temperaturas elevadas. Por lo tanto, en muchas aplicaciones de la industria qu\u00edmica donde existe un mayor riesgo de corrosi\u00f3n bajo tensi\u00f3n, tubos de acero inoxidable d\u00faplex<\/a> se utilizan a menudo en lugar de tubos de acero inoxidable austen\u00edtico.<\/p>","protected":false},"featured_media":5521,"template":"","categories":[186],"tags":[],"class_list":["post-5520","blog","type-blog","status-publish","has-post-thumbnail","hentry","category-stainless-steel-knowledge"],"yoast_head":"\nCharacteristics, Classification And Development Of Duplex Stainless Steel Pipes - 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\/caracteristicas-clasificacion-y-desarrollo-de-los-tubos-de-acero-inoxidable-duplex\/\" \/>\n<meta property=\"og:locale\" content=\"es_ES\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Characteristics, Classification And Development Of Duplex Stainless Steel Pipes - Stainless Steel Pipe and Fittings | KAYSUNS\" \/>\n<meta property=\"og:description\" content=\"Characteristics, Classification And Development Of Duplex Stainless Steel Pipes Development\u00a0of duplex stainless steel Duplex stainless steels are called \u201cduplex\u201d because their metallurgical microstructure consists of two types of ferrite and austenitic stainless steel grains.
