Atenci\u00f3n: La norma DIN 17458 ha sido actualizada y reemplazada por el reglamento europeo EN 10216-5.<\/span><\/p>\n

\u00c1mbito de aplicaci\u00f3n<\/h2>\n

El reglamento t\u00e9cnico DIN 17458 establece requisitos estrictos para la fabricaci\u00f3n de tubos sin costura de secci\u00f3n circular, hechos de aceros inoxidables austen\u00edticos. Estos productos, suministrados por EV Group China, est\u00e1n dise\u00f1ados para su uso en componentes cr\u00edticos de equipos energ\u00e9ticos y qu\u00edmicos, incluyendo generadores de vapor, sistemas de colectores, recipientes a presi\u00f3n y tuber\u00edas de alta intensidad. Los productos est\u00e1n dise\u00f1ados para un funcionamiento estable a temperaturas de hasta 600 \u00b0C, siempre que se cumplan las cargas de dise\u00f1o y se considere el entorno corrosivo y oxidante.<\/p>\n

Dentro de la especificaci\u00f3n, los materiales resistentes al calor incluyen aceros que mantienen altos niveles de resistencia mec\u00e1nica y resistencia a la deformaci\u00f3n bajo exposici\u00f3n t\u00e9rmica prolongada de hasta 600 \u00b0C.<\/p>\n

Composici\u00f3n qu\u00edmica de los aceros seg\u00fan la norma<\/h2>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
