Descripción
ASTM A790 UNS 31260 tubería de acero inoxidable dúplex
El dúplex es el acero inoxidable dúplex (acero inoxidable dúplex, denominado DSS ), se refiere al ferrítico y austenítico, cada uno representa aproximadamente el 50%, generalmente el contenido de la fase menor de la acero inoxidable debe alcanzar un mínimo del 30%. El acero inoxidable dúplex (DuplexTastinlesssteel, denominado DSS), se refiere a ferrita y austenita, cada uno representa aproximadamente el 50%, generalmente se debe alcanzar la fase menor del contenido de al menos el 30% del acero inoxidable.
En el caso de bajo contenido de C , contenido de Cr en 18% ~ 28%, contenido de Ni en 3% ~ 10%. Algún acero también contiene Mo, Cu, Nb, Ti, N
Algunos aceros también contienen Mo, Cu, Nb, Ti, N y otros elementos de aleación. Este tipo de acero, tanto las características de acero inoxidable austenítico como ferrítico, en comparación con el ferrítico, la plasticidad, la tenacidad es mayor, sin fragilidad de temperatura ambiente, la resistencia a la corrosión intergranular y la función de soldadura son un progreso significativo.
Al mismo tiempo, también mantiene la fragilidad de 475 ° C del acero inoxidable ferrítico, así como la alta conductividad térmica, la superplasticidad y otras características. En comparación con el acero inoxidable austenítico , la alta resistencia y la resistencia a la corrosión intergranular y la corrosión por estrés por cloruro ha mejorado significativamente. El acero inoxidable dúplex tiene una excelente resistencia a la función de corrosión de poros. Performance, también es un acero inoxidable que ahorra níquel. El acero inoxidable dúplex de la década de 1940 en los Estados Unidos desde su nacimiento se ha desarrollado para la tercera generación.
Su característica principal es la resistencia de rendimiento de hasta 400-550MPa, generalmente es 2 veces el acero inoxidable, por lo que puede ahorrar material, reducir los costos de producción de equipos. En términos de resistencia a la corrosión, especialmente el entorno de los medios es relativamente duro (como el agua de mar, el alto contenido de iones de cloruro), la resistencia a las picaduras de acero inoxidable dúplex, la corrosión de la grieta, la corrosión del estrés y la fatiga de la corrosión significativamente mejor que el acero inoxidable austenítico general.
