Con la continua actualizaci\u00f3n de las normas de ingenier\u00eda a nivel mundial, la adquisici\u00f3n de acero en el extranjero y la aceptaci\u00f3n de proyectos se han ido estandarizando cada vez m\u00e1s. Los cuatro principales sistemas de normas para el acero \u2014GB, ASTM, EN y JIS\u2014 se utilizan ampliamente en el comercio internacional. Es fundamental realizar una comparaci\u00f3n precisa de los materiales y verificar la conformidad con las normas para evitar problemas en el despacho de aduanas y el rechazo de los proyectos.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

1. Norma GB (norma china)<\/strong><\/h2>\n\n\n\n

La norma GB es la m\u00e1s habitual y rentable para proyectos de construcci\u00f3n general y estructuras de acero. Los grados t\u00edpicos Q235B y Q355B cuentan con existencias suficientes y un suministro estable. La mayor\u00eda de los proyectos de infraestructura de peque\u00f1a y mediana envergadura en el extranjero aceptan acero GB con certificados de terceros emitidos por SGS o BV. Sin embargo, los materiales GB no pueden sustituir a los grados ASTM o EN en proyectos industriales cr\u00edticos, mar\u00edtimos o de alta presi\u00f3n.<\/p>\n\n\n\n

2. Norma ASTM (norma estadounidense)<\/strong><\/h2>\n\n\n\n

La norma ASTM es obligatoria para proyectos en Norteam\u00e9rica, Oriente Medio, as\u00ed como en los sectores del petr\u00f3leo y el gas y la miner\u00eda. Entre los grados m\u00e1s comunes se incluyen el A36, el A572 Gr. 50, el A106 Gr. B y el A240 304\/316L. Esta norma exige un control estricto de la resistencia a la tracci\u00f3n, la tenacidad al impacto y la composici\u00f3n qu\u00edmica. Los proyectos industriales de alta gama y de recipientes a presi\u00f3n adoptan estrictamente los materiales conformes a la norma ASTM, sin sustituciones aleatorias.<\/p>\n\n\n\n

3. Norma EN (Norma Europea)<\/strong><\/h2>\n\n\n\n

Las normas EN son las m\u00e1s rigurosas a nivel mundial y se utilizan ampliamente en infraestructuras de alta gama, puentes y equipos a presi\u00f3n de la UE. Los principales grados \u2014S235JR, S355JR, 1.4307 y 1.4404\u2014 requieren la certificaci\u00f3n CE e informes de ensayo de terceros seg\u00fan la norma EN 10204 3.1\/3.2. Los proyectos europeos se centran en un bajo contenido en impurezas, una alta tenacidad y una trazabilidad completa de la producci\u00f3n.<\/p>\n\n\n\n

4. Norma JIS (Norma Japonesa)<\/strong><\/h2>\n\n\n\n

Las normas JIS son muy habituales en los proyectos del sudeste asi\u00e1tico y en aquellos financiados por Jap\u00f3n. Los grados t\u00edpicos SS400 y SM490 ofrecen un rendimiento estable, tolerancias precisas y una excelente calidad superficial, lo que los hace adecuados para la fabricaci\u00f3n mec\u00e1nica y la construcci\u00f3n de estructuras de acero. La mayor\u00eda de los clientes del sudeste asi\u00e1tico aceptan la sustituci\u00f3n por equivalentes de las normas JIS y GB en el caso de las piezas estructurales generales.<\/p>\n\n\n\n

5. Normas clave de emparejamiento internacional<\/strong><\/h2>\n\n\n\n

El acero estructural general puede equipararse de la siguiente manera: Q355B \u2248 S355JR \u2248 A572Gr50 \u2248 SM490. Para proyectos a baja temperatura, sometidos a presi\u00f3n y relacionados con el petr\u00f3leo y el gas, deben respetarse estrictamente las normas ASTM o EN. Los pedidos de la UE requieren la documentaci\u00f3n CE completa y certificados 3.2. Los proyectos de Oriente Medio y Norteam\u00e9rica exigen informes MTC completos y trazables. Cualquier sustituci\u00f3n de material debe ser confirmada previamente por el promotor del proyecto.<\/p>\n\n\n\n

With the continuous upgrading of global engineering standards, overseas steel procurement and project acceptance have become increasingly standardized. Four major steel standard systems, including GB, ASTM, EN and JIS, are widely adopted in international trades.
