Introducci\u00f3n de acero inoxidable d\u00faplex<\/h2>\n\n\n\n

El acero inoxidable d\u00faplex se refiere al material cuya microestructura est\u00e1 compuesta de ferrita y austenita, cada una de las cuales representa aproximadamente 50%. En uso real, uno de ellos es m\u00e1s adecuado entre 40-60%.<\/p>\n\n\n\n

De acuerdo con las caracter\u00edsticas de las dos estructuras, mediante el correcto control de la composici\u00f3n qu\u00edmica y el proceso de tratamiento t\u00e9rmico, la excelente tenacidad y soldabilidad del acero inoxidable austen\u00edtico se combinan con la mayor resistencia y resistencia a la corrosi\u00f3n bajo tensi\u00f3n por cloruros del acero inoxidable ferr\u00edtico. acero inoxidable un tipo de acero que combina una excelente resistencia a la corrosi\u00f3n, alta resistencia y f\u00e1cil procesamiento y fabricaci\u00f3n.<\/p>\n\n\n\n

Las propiedades f\u00edsicas del acero inoxidable d\u00faplex se encuentran entre el acero inoxidable austen\u00edtico y el acero inoxidable ferr\u00edtico, pero est\u00e1n m\u00e1s cerca del acero inoxidable ferr\u00edtico y el acero al carbono.<\/p>\n\n\n\n

La resistencia a la corrosi\u00f3n y la resistencia a la corrosi\u00f3n por fisuras de los tubos de acero inoxidable d\u00faplex est\u00e1n relacionadas con el contenido de cromo, molibdeno<\/a> y nitr\u00f3geno. La resistencia a la corrosi\u00f3n y la resistencia a la corrosi\u00f3n por grietas de tubos de acero inoxidable d\u00faplex<\/a> puede ser similar a Tubos de acero inoxidable 316<\/a> o m\u00e1s alto que el agua de mar tubos de acero inoxidable<\/a> como tubo de acero inoxidable 6%.<\/p>\n\n\n\n

Todos los aceros inoxidables d\u00faplex son significativamente m\u00e1s resistentes al cloruro agrietamiento por corrosi\u00f3n bajo tensi\u00f3n<\/a> que los aceros inoxidables austen\u00edticos de la serie 300, y su resistencia es muy superior a la de los aceros inoxidables austen\u00edticos. Tambi\u00e9n presentan buena plasticidad y tenacidad.<\/p>\n\n\n\n

El acero inoxidable d\u00faplex se puede dividir generalmente en cuatro tipos: tipo de baja aleaci\u00f3n, tipo de aleaci\u00f3n media, tipo de alta aleaci\u00f3n y tipo de acero inoxidable s\u00faper d\u00faplex.<\/p>\n\n\n\n
