Dado que no se especifican bajo el mismo sistema, los ingenieros y compradores deben verificar los l\u00edmites qu\u00edmicos y la certificaci\u00f3n antes de considerarlos sustitutos directos.<\/p>\n\n\n\n<p>Para obtener una visi\u00f3n general m\u00e1s amplia de las equivalencias entre est\u00e1ndares y las comparaciones de calificaciones, consulte la <a href=\"https:\/\/aobosteel.com\/es\/h13-equivalent-comparison-guide\/\">Gu\u00eda de comparaci\u00f3n y equivalencia del H13<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u00bfSon H13 y SKD61 lo mismo?<\/h2>\n\n\n\n<p>En la pr\u00e1ctica industrial, el acero SKD61 se considera com\u00fanmente el equivalente japon\u00e9s del H13. Ambos grados pertenecen a la misma familia de aceros para herramientas de trabajo en caliente de cromo-molibdeno-vanadio y est\u00e1n destinados a herramientas expuestas a altas temperaturas, esfuerzos mec\u00e1nicos y ciclos t\u00e9rmicos.<\/p>\n\n\n\n<p>En rigor, no son id\u00e9nticos. H13 y SKD61 se rigen por normas diferentes, y sus rangos qu\u00edmicos admisibles no coinciden exactamente. Por este motivo, la sustituci\u00f3n debe confirmarse con la especificaci\u00f3n requerida y el informe de ensayo del material del lote suministrado.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Designaciones regionales<\/h2>\n\n\n\n<p>H13 es una designaci\u00f3n estadounidense de acero para herramientas de trabajo en caliente, definida seg\u00fan las normas ASTM A681 y AISI. Pertenece a la serie H de aceros al cromo para trabajo en caliente.<\/p>\n\n\n\n<p>SKD61 se define seg\u00fan la norma JIS G4404, la norma industrial japonesa para aceros para herramientas. Es la designaci\u00f3n japonesa que se suele asociar con H13 en las discusiones sobre herramientas para trabajo en caliente.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Comparaci\u00f3n de la composici\u00f3n qu\u00edmica<\/h2>\n\n\n\n<p>La tabla que aparece a continuaci\u00f3n muestra los rangos de composici\u00f3n t\u00edpicos definidos por las dos normas.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Elemento<\/td><td>ASTM A681 H13 (peso %)<\/td><td>JIS G4404 SKD61 (peso %)<\/td><\/tr><tr><td>Carbono (C)<\/td><td>0,32 \u2013 0,45<\/td><td>0.32 - 0.42<\/td><\/tr><tr><td>Silicio (Si)<\/td><td>0,80 \u2013 1,25<\/td><td>0.80 - 1.20<\/td><\/tr><tr><td>Manganeso (Mn)<\/td><td>0.20 - 0.60<\/td><td>0,50 (m\u00e1x.\/nominal)<\/td><\/tr><tr><td>Cromo (Cr)<\/td><td>4.75 - 5.50<\/td><td>4.50 \u2013 5.50<\/td><\/tr><tr><td>Molibdeno (Mo)<\/td><td>1.10 \u2013 1.75<\/td><td>1.00 \u2013 1.50<\/td><\/tr><tr><td>Vanadio (V)<\/td><td>0.80 - 1.20<\/td><td>0.80 - 1.20<\/td><\/tr><tr><td>F\u00f3sforo (P)<\/td><td>0,030 m\u00e1x.<\/td><td>0,030 m\u00e1x.<\/td><\/tr><tr><td>Azufre (S)<\/td><td>0,030 m\u00e1x.<\/td><td>0,030 m\u00e1x.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>La gran coincidencia en los conocimientos qu\u00edmicos es la raz\u00f3n principal por la que ambos grados se suelen utilizar como referencias cruzadas en el comercio internacional.<\/p>\n\n\n\n<p>Nota sobre las propiedades mec\u00e1nicas:<br>Las propiedades mec\u00e1nicas, como la dureza, la resistencia y la tenacidad al impacto, dependen en gran medida del tratamiento t\u00e9rmico y del proceso de fabricaci\u00f3n, y no solo de la clasificaci\u00f3n del grado.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Similitudes entre H13 y SKD61<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Pertenecen a la misma familia de aleaciones. Ambos grados son aceros para herramientas de trabajo en caliente de cromo-molibdeno-vanadio, destinados a funcionar a temperaturas elevadas.<\/li>\n\n\n\n<li>Dise\u00f1o qu\u00edmico similar. Sus rangos de aleaci\u00f3n especificados son muy similares, especialmente en cromo, molibdeno y vanadio. Este dise\u00f1o de aleaci\u00f3n similar es la raz\u00f3n por la que a menudo se consideran grados equivalentes.<\/li>\n\n\n\n<li>Entornos de servicio similares. Ambos grados se utilizan en entornos exigentes de herramientas para trabajo en caliente, como fundici\u00f3n a presi\u00f3n, forja, extrusi\u00f3n en caliente, pasadores de n\u00facleo y mandriles.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Diferencias clave entre H13 y SKD61<\/h2>\n\n\n\n<p>Aunque ambos grados son pr\u00e1cticamente equivalentes, sus especificaciones no son id\u00e9nticas.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Rango de carbono. SKD61 tiene un rango de carbono ligeramente m\u00e1s estrecho, con un l\u00edmite superior de 0,42%, mientras que H13 permite hasta 0,45%.<\/li>\n\n\n\n<li>L\u00edmite de molibdeno. H13 permite hasta 1,75% de molibdeno, mientras que SKD61 lo limita a 1,50%.<\/li>\n\n\n\n<li>M\u00ednimo de cromo. H13 especifica un contenido m\u00ednimo de cromo ligeramente superior, de 4,751 TP3T, mientras que SKD61 comienza en 4,501 TP3T.<\/li>\n<\/ul>\n\n\n\n<p>Estas diferencias son peque\u00f1as, pero demuestran que H13 y SKD61 son grados equivalentes en lugar de especificaciones id\u00e9nticas.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Consideraciones sobre la sustituci\u00f3n<\/h2>\n\n\n\n<p>En muchas aplicaciones de utillaje, los materiales H13 y SKD61 pueden sustituirse entre s\u00ed sin diferencias pr\u00e1cticas importantes. Sin embargo, conviene verificar la sustituci\u00f3n conforme a la norma requerida.<\/p>\n\n\n\n<p>Por ejemplo, un lote de H13 que contiene molibdeno 1,70% cumplir\u00eda con la norma ASTM A681, pero estar\u00eda fuera del l\u00edmite de molibdeno SKD61 seg\u00fan la norma JIS G4404. En ese caso, el material cumple con una norma pero no con la otra.<\/p>\n\n\n\n<p>Por este motivo, los ingenieros y compradores deben confirmar que el calor suministrado se ajusta a las especificaciones requeridas por el plano, la orden de compra o el cliente final.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusi\u00f3n<\/h2>\n\n\n\n<p><a href=\"https:\/\/aobosteel.com\/es\/h13-tool-steel\/\">H13<\/a> Los aceros SKD61 y SKD61 son grados de acero para herramientas de trabajo en caliente estrechamente relacionados, definidos por las normas estadounidenses y japonesas.
