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 tratan como grados equivalentes.<\/li>\n        <li>Entornos de servicio similares. Ambos grados se utilizan en entornos exigentes de herramientas de trabajo en caliente como fundici\u00f3n a presi\u00f3n, forja, extrusi\u00f3n en caliente, pasadores de n\u00facleo y mandriles.<\/li>\n      <\/ul>\n      <h2>Diferencias clave entre H13 y SKD61<\/h2>\n      <p>Aunque los dos grados son equivalentes cercanos, sus especificaciones no son id\u00e9nticas.<\/p>\n      <ul class=\"aobo-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        <li>L\u00edmite de molibdeno. H13 permite hasta 1,75 % de molibdeno, mientras que SKD61 lo limita a 1,50 %.<\/li>\n        <li>M\u00ednimo de cromo. H13 especifica un contenido m\u00ednimo de cromo ligeramente superior de 4,75 %, mientras que SKD61 comienza en 4,50 %.<\/li>\n      <\/ul>\n      <p>Estas diferencias son peque\u00f1as, pero muestran que H13 y SKD61 son grados equivalentes en lugar de especificaciones id\u00e9nticas.<\/p>\n      <h2>Consideraciones de sustituci\u00f3n<\/h2>\n      <p>En muchas aplicaciones de herramientas, H13 y SKD61 pueden sustituirse entre s\u00ed sin diferencias pr\u00e1cticas importantes. Sin embargo, la sustituci\u00f3n debe verificarse con la norma requerida.<\/p>\n      <p>Por ejemplo, un lote de H13 que contenga 1,70 % de molibdeno cumplir\u00eda con ASTM A681 pero quedar\u00eda fuera del l\u00edmite de molibdeno de SKD61 bajo JIS G4404. En ese caso, el material cumple con una norma pero no con la otra.<\/p>\n      <p>Por esta raz\u00f3n, los ingenieros y compradores deben confirmar que la colada suministrada coincide con la especificaci\u00f3n requerida por el plano, la orden de compra o el cliente final.<\/p>\n      <h2>Conclusi\u00f3n<\/h2>\n      <p><a href=\"https:\/\/aobosteel.com\/es\/h13-tool-steel\/\">H13<\/a> y SKD61 son grados de acero para herramientas de trabajo en caliente estrechamente relacionados definidos por normas estadounidenses y japonesas.
