id=\"h-selection-of-tool-steel-for-trimming-dies\">Selecci\u00f3n de aceros para herramientas para matrices de recorte<\/h1>\n      <p>Las matrices de recorte son herramientas de operaci\u00f3n secundaria que se utilizan para eliminar el exceso de material, como rebabas, canales de alimentaci\u00f3n, reboses y respiraderos, de las piezas forjadas o fundidas a presi\u00f3n. Seg\u00fan el proceso, el recorte puede realizarse en fr\u00edo (normalmente por debajo de 150 \u00b0C \/ 300 \u00b0F) o en caliente (hasta 980 \u00b0C \/ 1800 \u00b0F para determinadas aleaciones). La lista de grados preseleccionados para el caso en caliente se encuentra en la <a href=\"https:\/\/aobosteel.com\/es\/selection-of-tool-steel-for-hot-trimming-dies\/\">gu\u00eda de selecci\u00f3n de acero para matrices de recorte en caliente<\/a>.<\/p>\n      <p>Durante el funcionamiento, el filo de corte est\u00e1 sometido a altas tensiones de cizallamiento, cargas de impacto y fricci\u00f3n continua. En aplicaciones de forja, la capa de \u00f3xido acelera a\u00fan m\u00e1s el desgaste abrasivo. Como resultado, la falla de la matriz de recorte se debe con mayor frecuencia al astillamiento, la fractura o la r\u00e1pida degradaci\u00f3n del filo, en lugar de a un desgaste uniforme.<\/p>\n    <\/header>\n\n    <main class=\"aobo-article\">\n      <h2>Factores de selecci\u00f3n<\/h2>\n      <p>La selecci\u00f3n del acero para herramientas utilizado en matrices de recorte se rige por el equilibrio entre la resistencia al desgaste y la tenacidad, as\u00ed como por la estabilidad t\u00e9rmica durante las operaciones en caliente.<\/p>\n      <h3>Resistencia al desgaste frente a tenacidad<\/h3>\n      <p>El filo debe resistir el desgaste abrasivo provocado por la cascarilla y el material de la pieza de trabajo para mantener su nitidez y precisi\u00f3n dimensional.<\/p>\n      <p>Sin embargo, una mayor dureza y un mayor contenido de carburo reducen la tenacidad. En las operaciones de recorte, especialmente con secciones gruesas, cargas desiguales o desalineaci\u00f3n, las cargas de impacto son inevitables. Si la tenacidad es insuficiente, la falla se produce por astillamiento del borde o fractura fr\u00e1gil, en lugar de desgaste gradual.<\/p>\n      <p>El requisito no es la m\u00e1xima dureza, sino un equilibrio que mantenga la estabilidad del filo tanto ante la abrasi\u00f3n como ante el impacto.<\/p>\n      <h3>Dureza en caliente y resistencia al agrietamiento por calor.<\/h3>\n      <p>En el recorte en caliente, los efectos t\u00e9rmicos se vuelven cruciales.<\/p>\n      <p>El acero para herramientas debe conservar su resistencia a temperaturas elevadas para evitar la deformaci\u00f3n del filo. Al mismo tiempo, los ciclos repetidos de calentamiento y enfriamiento generan fatiga t\u00e9rmica, lo que provoca el agrietamiento de la superficie (fisuraci\u00f3n por calor).<\/p>\n      <p>Una vez que se inician las grietas, se propagan bajo tensi\u00f3n mec\u00e1nica, acelerando la rotura del filo. Por lo tanto, la resistencia al ablandamiento t\u00e9rmico y a la fatiga t\u00e9rmica determina directamente la vida \u00fatil de la herramienta en condiciones de recorte en caliente.<\/p>\n      <h2>Aceros para herramientas recomendados<\/h2>\n      <div class=\"aobo-grade-card\">\n        <h3 id=\"h-aisi-d2-tool-steel-1-2379-skd11\">Acero para herramientas AISI D2 | 1.2379 | SKD11<\/h3>\n        <p>AISI D2 se utiliza ampliamente donde el desgaste abrasivo es el factor dominante, particularmente en <a href=\"https:\/\/aobosteel.com\/es\/forging-trimming-and-punching-die-materials\/\">Recorte en fr\u00edo<\/a> operaciones con largas series de producci\u00f3n.<\/p>\n        <p>Su alto contenido en carbono y cromo produce un gran volumen de carburos duros, lo que proporciona una fuerte resistencia a la abrasi\u00f3n y una excelente retenci\u00f3n del filo. Utilizado normalmente a 58-60 HRC, el acero D2 mantiene su rendimiento de corte durante ciclos prolongados.<\/p>\n        <p>Debido a su limitada tenacidad, el acero D2 no es adecuado para condiciones de alto impacto. Puede utilizarse en aplicaciones restringidas de recorte en caliente (como en el caso de los aceros inoxidables) donde la resistencia al desgaste es m\u00e1s importante que la resistencia a la fatiga t\u00e9rmica, pero no es una soluci\u00f3n general para el trabajo en caliente.<\/p>\n        <div class=\"aobo-cta-row\">\n          <div class=\"popmake-16052 hs-cta-trigger-button hs-cta-trigger-button-230288465624\"><a class=\"aobo-btn aobo-btn-primary\">Enviar consulta ahora<\/a><\/div>\n          <a class=\"aobo-btn aobo-btn-secondary\" href=\"https:\/\/aobosteel.com\/es\/d2-tool-steel\/\">Ver detalles de suministro de material D2<\/a>\n        <\/div>\n      <\/div>\n      <div class=\"aobo-grade-card\">\n        <h3 id=\"h-aisi-a2-tool-steel-1-2363-skd12\">Acero para herramientas AISI A2 | 1.2363 | SKD12<\/h3>\n        <p>El acero AISI A2 proporciona una combinaci\u00f3n m\u00e1s equilibrada de resistencia al desgaste y tenacidad.<\/p>\n        <p>Con un menor contenido de carburo que el D2, el A2 ofrece una mayor resistencia al astillamiento del filo, manteniendo un rendimiento de desgaste adecuado.
