Colocar acero para herramientas D3 a temperatura ambiente directamente en un horno de alta temperatura puede causar f\u00e1cilmente choque t\u00e9rmico y provocar agrietamiento. Por lo tanto, el calentamiento debe comenzar muy lentamente desde temperatura ambiente. Precaliente el componente a 815\u00b0C (1500\u00b0F) y mant\u00e9ngalo a esta temperatura hasta que se caliente de manera uniforme. Solo entonces debe elevarse la temperatura del horno hasta la temperatura de austenizaci\u00f3n.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Austenizaci\u00f3n (endurecimiento)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Siguiendo el paso anterior, caliente el horno a 925\u00b0C a 980\u00b0C (1700\u00b0F a 1795\u00b0F). Las piezas peque\u00f1as de D3 requieren una permanencia de 15 minutos, mientras que las piezas grandes pueden permanecer hasta 45 minutos. El control de la atm\u00f3sfera durante el calentamiento es esencial para prevenir la descarburaci\u00f3n. Se prefieren los hornos de vac\u00edo, ya que previenen la descarburaci\u00f3n y preservan la superficie brillante del acero para herramientas D3. Si no se dispone de dicho equipo, el acero para herramientas D3 debe envolverse bien en l\u00e1mina de acero inoxidable o empacarse en materiales limpios, secos e inertes, como virutas de hierro fundido.<\/p>\n\n\n\n<div class=\"wp-block-uagb-container uagb-block-f619b717\">\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"765\" src=\"https:\/\/aobosteel.com\/wp-content\/uploads\/2026\/01\/D3-Tool-Steel-Isothermal-Transformation-Diagram.avif\" alt=\"D3 Tool Steel Isothermal Transformation Diagram\" class=\"wp-image-11918\" srcset=\"https:\/\/aobosteel.com\/wp-content\/uploads\/2026\/01\/D3-Tool-Steel-Isothermal-Transformation-Diagram.avif 1024w, https:\/\/aobosteel.com\/wp-content\/uploads\/2026\/01\/D3-Tool-Steel-Isothermal-Transformation-Diagram-300x224.avif 300w, https:\/\/aobosteel.com\/wp-content\/uploads\/2026\/01\/D3-Tool-Steel-Isothermal-Transformation-Diagram-768x574.avif 768w, https:\/\/aobosteel.com\/wp-content\/uploads\/2026\/01\/D3-Tool-Steel-Isothermal-Transformation-Diagram-16x12.avif 16w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Diagrama de transformaci\u00f3n isot\u00e9rmica del acero para herramientas D3.

Durante la operaci\u00f3n, los componentes deben transferirse r\u00e1pidamente del horno al ba\u00f1o de aceite y templarse hasta que la temperatura de la pieza alcance aproximadamente 50\u00b0C a 66\u00b0C (120\u00b0F a 150\u00b0F), es decir, deben retirarse mientras la herramienta permanezca tibia al tacto. Nunca permita que la herramienta alcance la temperatura ambiente antes del revenido, ya que esto aumenta significativamente el riesgo de agrietamiento. La dureza esperada despu\u00e9s de este proceso es de aproximadamente 64 a 66 HRC.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Revenido<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Dado que la martensita templada es extremadamente fr\u00e1gil y est\u00e1 sometida a alta tensi\u00f3n interna, no revenir de inmediato puede causar agrietamiento. Por lo tanto, el revenido debe realizarse inmediatamente despu\u00e9s del temple. La pr\u00e1ctica est\u00e1ndar para los aceros de la serie D es emplear un proceso de revenido en dos pasos para transformar <a href=\"https:\/\/aobosteel.com\/es\/tool-steel-size-change-in-heat-treatment\/\">austenita retenida<\/a> y eliminar las tensiones martens\u00edticas formadas durante el enfriamiento del primer revenido. El proceso espec\u00edfico es el siguiente: Caliente el D3 a la temperatura de revenido. El tiempo de permanencia se calcula como 1 hora por pulgada (25 mm) de espesor del acero para herramientas. Para mayor estabilidad, generalmente se recomienda un m\u00ednimo de 2 horas. Despu\u00e9s de que la herramienta se enfr\u00ede a temperatura ambiente, recali\u00e9ntela a la misma temperatura para el segundo revenido.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Temperatura de revenido<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\"><strong>Rockwell C (HRC)<\/strong><\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Reci\u00e9n templado<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\"><strong>66<\/strong><\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">300 \u00b0F \/ 150 \u00b0C<\/td><td class=\"has-text-align-center\" data-align=\"center\">65<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">400 \u00b0F \/ 205 \u00b0C<\/td><td class=\"has-text-align-center\" data-align=\"center\">61<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">500 \u00b0F \/ 260 \u00b0C<\/td><td class=\"has-text-align-center\" data-align=\"center\">58<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">600 \u00b0F \/ 315 \u00b0C<\/td><td class=\"has-text-align-center\" data-align=\"center\">57<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">700 \u00b0F \/ 370 \u00b0C<\/td><td class=\"has-text-align-center\" data-align=\"center\">57<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">800 \u00b0F \/ 425 \u00b0C<\/td><td class=\"has-text-align-center\" data-align=\"center\">56<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">900 \u00b0F \/ 480 \u00b0C<\/td><td class=\"has-text-align-center\" data-align=\"center\">55<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">1000 \u00b0F \/ 540 \u00b0C<\/td><td class=\"has-text-align-center\" data-align=\"center\">52<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">TEMPERATURA DE PRECALENTAMIENTO:1200\u00b0F\/650\u00b0C TEMPERATURA DE ENDURECIMIENTO:&nbsp;1725\u00b0F\/940\u00b0C TEMPLE EN ACEITE QU\u00cdMICA:&nbsp;Carbono 2.15% Manganeso:&nbsp;0.40% Silicio: 0.40% Cromo:&nbsp;12.25% Fuente: <em>Heat Treatment, Selection, and Application of Tool Steels<\/em> por William E.

El proceso requiere enfriamiento continuo desde el temple hasta -75\u00b0C a -196\u00b0C, seguido de revenido inmediato al regresar a temperatura ambiente para aliviar las tensiones internas.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Problemas comunes y soluciones en el tratamiento t\u00e9rmico del D3<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">agrietamiento por temple<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">El agrietamiento por temple se refiere a fracturas que ocurren durante o inmediatamente despu\u00e9s de la etapa de temple. Dado que el acero D3 requiere un temple en aceite m\u00e1s agresivo que el enfriamiento al aire, el agrietamiento generalmente ocurre si los componentes se enfr\u00edan excesivamente en el medio de temple (por debajo de 50\u00b0C) o si hay un retraso entre el temple y el revenido. Adem\u00e1s, las altas tensiones internas resultantes de un endurecimiento desigual\u2014donde la superficie se endurece pero el interior permanece sin endurecer\u2014tambi\u00e9n contribuyen a este fen\u00f3meno.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La soluci\u00f3n es asegurar un precalentamiento adecuado para minimizar el choque t\u00e9rmico y retirar los componentes del aceite cuando alcancen temperaturas tibias al tacto (50\u00b0C\u201366\u00b0C), luego colocarlos inmediatamente en un horno de revenido precalentado.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Dureza baja<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">La dureza insuficiente ocurre cuando un acero para herramientas D3 no alcanza el HRC esperado. Generalmente hay dos causas: primero, control inadecuado de la atm\u00f3sfera del tratamiento t\u00e9rmico, lo que provoca descarburaci\u00f3n superficial; segundo, temperaturas de austenizaci\u00f3n excesivamente altas, que estabilizan la austenita, impiden su transformaci\u00f3n en martensita y resultan en austenita retenida.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Puntos blandos<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Los puntos blandos son \u00e1reas localizadas de dureza reducida en la superficie del acero para herramientas D3. Esto ocurre porque durante el temple en aceite, puede formarse una pel\u00edcula de vapor con baja conductividad t\u00e9rmica alrededor del acero D3. Esta pel\u00edcula reduce la velocidad de enfriamiento de las \u00e1reas cubiertas, inhibiendo as\u00ed la formaci\u00f3n de martensita en estas regiones.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La soluci\u00f3n es romper la pel\u00edcula de vapor durante el proceso de temple del D3 agitando el ba\u00f1o de aceite o moviendo el D3, asegurando as\u00ed una transferencia de calor uniforme.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Distorsi\u00f3n dimensional<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">La distorsi\u00f3n dimensional se refiere a los cambios dimensionales o alabeo que ocurren en el D3 durante el tratamiento t\u00e9rmico. Esto se debe a que el D3 es un acero de temple profundo, y la transformaci\u00f3n de fase de austenita a martensita causa expansi\u00f3n volum\u00e9trica; las tensiones t\u00e9rmicas generadas por un calentamiento o enfriamiento desigual exacerban la distorsi\u00f3n.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" id=\"h-\">Existen dos enfoques para resolver este problema. Primero, mantener la simetr\u00eda de la secci\u00f3n transversal tanto como sea posible durante el dise\u00f1o de herramientas y matrices. Segundo, realizar un tratamiento de alivio de tensiones despu\u00e9s del mecanizado en bruto del D3 y antes del temple. Utilizar precalentamiento escalonado para asegurar una distribuci\u00f3n uniforme de la temperatura antes de alcanzar altas temperaturas, y emplear temple vertical para minimizar el alabeo. Adem\u00e1s, dejar sobreespesor de mecanizado para el rectificado posterior al temple.<\/p>\n\n\n\n<div class=\"wp-block-uagb-container uagb-block-1db8efa3 alignfull uagb-is-root-container\"><div class=\"uagb-container-inner-blocks-wrap\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-7387b849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"border-left-color:var(--wp--preset--color--ast-global-color-0);padding-left:var(--wp--preset--spacing--30);flex-basis:66.66%\">\n<div class=\"wp-block-uagb-advanced-heading uagb-block-f814b1a5\"><h3 class=\"uagb-heading-text\">Un tratamiento t\u00e9rmico estable del D3 comienza con acero para herramientas de calidad<\/h3><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Obtenga resultados consistentes de tratamiento t\u00e9rmico y m\u00e1xima resistencia al desgaste.
