id=\"h-tool-steel-selection-for-blanking-and-piercing-dies\">Selecci\u00f3n de acero para herramientas para troqueles de corte y punzonado<\/h1>\n      <p>Los troqueles de corte y punzonado trabajan bajo una combinaci\u00f3n de alta tensi\u00f3n de compresi\u00f3n, liberaci\u00f3n s\u00fabita de fractura y contacto repetido del borde con el material de trabajo. Cuando el punz\u00f3n penetra en la chapa, el borde de corte queda expuesto a presi\u00f3n, fricci\u00f3n, calentamiento localizado e impacto en la ruptura. Como resultado, estas herramientas suelen fallar de una de dos maneras: el borde de corte se desgasta progresivamente, o se astilla y agrieta bajo cargas de impacto.<\/p>\n      <p>Por esta raz\u00f3n, la selecci\u00f3n de acero para herramientas para troqueles de corte y punzonado no es cuesti\u00f3n de elegir el grado m\u00e1s duro o el m\u00e1s resistente al desgaste. La verdadera tarea es adecuar el acero al modo de fallo dominante en producci\u00f3n.<\/p>\n    <\/header>\n\n    <main class=\"aobo-article\">\n      <h2>Principio de selecci\u00f3n fundamental<\/h2>\n      <p>El problema central de selecci\u00f3n en troqueles de corte y punzonado es equilibrar la resistencia al desgaste y la tenacidad.<\/p>\n      <p>Si la resistencia al desgaste es demasiado baja, el borde de corte pierde filo r\u00e1pidamente. Aumentan las rebabas, las dimensiones de la pieza se desv\u00edan y la frecuencia de rectificado aumenta. Si la tenacidad es demasiado baja, el borde de corte no puede tolerar el impacto de ruptura, y el astillamiento o el agrietamiento comienza mucho antes de alcanzar la vida \u00fatil normal frente al desgaste.<\/p>\n      <p>Esto significa que el grado correcto depende principalmente de tres condiciones de producci\u00f3n: volumen de producci\u00f3n, espesor del material y severidad del impacto durante el corte. Las aplicaciones de gran volumen con desgaste abrasivo orientan la selecci\u00f3n hacia una mayor resistencia al desgaste. El material de gran espesor, la carga inestable o el impacto severo de ruptura orientan la selecci\u00f3n hacia una mayor tenacidad.<\/p>\n      <h2>Selecci\u00f3n de los aceros para herramientas m\u00e1s comunes<\/h2>\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>A2 es una opci\u00f3n equilibrada para troqueles de corte y punzonado que trabajan con desgaste e impacto moderados. Ofrece mejor tenacidad que D2 y mejor resistencia al desgaste que los aceros resistentes al impacto como S7. Esto lo hace adecuado para series de producci\u00f3n medianas en las que el troquel debe resistir tanto el desgaste del borde como impactos ocasionales sin volverse excesivamente fr\u00e1gil.<\/p>\n        <p>A2 se selecciona a menudo cuando la aplicaci\u00f3n no exige claramente ni la m\u00e1xima resistencia al desgaste ni la m\u00e1xima resistencia al impacto.<\/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\/a2-tool-steel\/\">Ver detalles de suministro de material A2<\/a>\n        <\/div>\n      <\/div>\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>D2 se utiliza cuando el desgaste abrasivo es la causa principal del fallo del troquel. Su alto contenido de carburos le confiere una elevada retenci\u00f3n del filo, lo cual es valioso en series de producci\u00f3n largas y en operaciones donde mantener la geometr\u00eda del borde de corte es cr\u00edtico.<\/p>\n        <p>Sin embargo, D2 es menos tolerante al impacto de ruptura que A2 o S7. En troqueles de corte y punzonado sometidos a material de gran espesor, condiciones de prensa inestables o cargas de alto impacto, es m\u00e1s probable que D2 se astille en el borde. Por lo tanto, es m\u00e1s adecuado para trabajos de alto volumen donde la carga es relativamente estable y el control del desgaste importa m\u00e1s que la resistencia al impacto.<\/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-s7-tool-steel-1-2550\">Acero para herramientas AISI S7 | 1.2550<\/h3>\n        <p>S7 se elige cuando el fallo del troquel se debe al impacto y no al desgaste.
