An\u00e1lisis de las caracter\u00edsticas del acero inoxidable Duplex 2205<\/h2>\n

Los principales elementos de aleaci\u00f3n del acero inoxidable d\u00faplex 2205 son Cr, Ni, Mo y N, cuyo contenido de Cr es 22%. Cr y Mo se utilizan para aumentar el contenido de ferrita, mientras que Ni y N son elementos estabilizadores de austenita. Algunos tipos de acero tambi\u00e9n contienen elementos como Mn, Cu y W.<\/p>\n

Cr, Ni y Mo pueden mejorar la resistencia a la corrosi\u00f3n, y el rendimiento de corrosi\u00f3n por picaduras y grietas es particularmente bueno en el ambiente que contiene cloruro. N es un elemento formador de austenita que aumenta la resistencia a la corrosi\u00f3n por picaduras y grietas de los aceros inoxidables d\u00faplex. El nitr\u00f3geno puede retrasar la precipitaci\u00f3n de los huecos met\u00e1licos y reducir la tendencia a formar fases \u03c3 en los aceros inoxidables d\u00faplex.<\/p>\n

Las propiedades mec\u00e1nicas del acero inoxidable d\u00faplex est\u00e1n relacionadas con la temperatura de revenido de la placa de acero. Cuanto mayor sea la temperatura de revenido, menor ser\u00e1 la resistencia.<\/p>\n

Cuando la temperatura de revenido es de 600 \u2103, el l\u00edmite el\u00e1stico es de 400 MPa y la resistencia a la tracci\u00f3n es de 650 MPa.<\/p>\n

La Figura 1 muestra la estructura metal\u00fargica del acero inoxidable d\u00faplex 2205 (corrosivo 30g K (OH) + 30g K3 Fe (CN) 6 + 100ml H2O). La estructura metal\u00fargica del acero inoxidable d\u00faplex consta de ferrita alfa (negra) y austenita gamma. El cuerpo (blanco) se compone de dos fases y tiene las caracter\u00edsticas de una fracci\u00f3n de volumen sustancialmente igual.<\/p>\n

Por lo tanto, el acero inoxidable d\u00faplex tiene las caracter\u00edsticas duales del acero inoxidable austen\u00edtico y del acero inoxidable ferr\u00edtico. En comparaci\u00f3n con el acero inoxidable ferr\u00edtico, tiene una gran tenacidad, una baja temperatura de transici\u00f3n d\u00factil-fr\u00e1gil, una mejora significativa de la... corrosi\u00f3n intergranular<\/a> En comparaci\u00f3n con el acero inoxidable austen\u00edtico, el l\u00edmite el\u00e1stico y la resistencia a la fatiga han mejorado significativamente, aproximadamente el doble que en el caso del acero inoxidable austen\u00edtico, y la resistencia a la corrosi\u00f3n intergranular, la corrosi\u00f3n bajo tensi\u00f3n y la fatiga por corrosi\u00f3n ha mejorado significativamente.<\/p>\n

El nitr\u00f3geno juega un papel importante en el fortalecimiento del acero inoxidable d\u00faplex 2205, pero cuando la fracci\u00f3n de masa de nitr\u00f3geno excede 0.2%, la resistencia de la austenita es mayor que la de la ferrita debido al fortalecimiento de la soluci\u00f3n s\u00f3lida intersticial del nitr\u00f3geno. El aumento del contenido de ferrita har\u00e1 que disminuya la tenacidad al impacto y tambi\u00e9n provocar\u00e1 la precipitaci\u00f3n de nitr\u00f3geno en la ferrita, lo que dar\u00e1 como resultado la formaci\u00f3n de nitruro de cromo, porque el nitr\u00f3geno tiene una menor solubilidad en ferrita que en austenita.<\/p>\n

El tratamiento en fr\u00edo puede reducir la tenacidad al impacto del acero inoxidable d\u00faplex 2205 y aumentar la temperatura de transici\u00f3n d\u00factil-fr\u00e1gil. Y el envejecimiento en el rango de 280-350 \u2103 tambi\u00e9n conducir\u00e1 a una menor tenacidad.<\/p>\n
