<h2>\u00bfQu\u00e9 es el acero para herramientas de temple al aire?<\/h2>\n\n      <p>\n        Los aceros para herramientas de temple al aire contienen suficiente carbono y elementos de aleaci\u00f3n para endurecerse durante el enfriamiento al aire desde la temperatura de austenizaci\u00f3n. En el sistema AISI, la serie A es el grupo principal de aceros para herramientas de trabajo en fr\u00edo de temple al aire. A2, <a href=\"https:\/\/aobosteel.com\/es\/a6-tool-steel-heat-treatment\/\">A6<\/a>, y A7 son ejemplos t\u00edpicos.\n      <\/p>\n\n      <p>\n        En la selecci\u00f3n pr\u00e1ctica de aceros para herramientas, el comportamiento de temple al aire tambi\u00e9n aparece fuera de la serie A. D2, H13, S7, M2 y muchos otros aceros para herramientas de alta aleaci\u00f3n tambi\u00e9n pueden endurecerse mediante enfriamiento al aire, aire forzado o gas. El punto com\u00fan es la alta templabilidad.\n      <\/p>\n\n      <p>\n        La templabilidad es la capacidad del acero de endurecerse a trav\u00e9s de su secci\u00f3n durante el temple. En el acero para herramientas de temple al aire, la alta templabilidad permite que el acero se endurezca sin temple en agua o aceite.\n      <\/p>\n\n      <h2>\u00bfC\u00f3mo funciona el acero para herramientas de temple al aire?<\/h2>\n\n      <p>\n        El endurecimiento del acero depende de la formaci\u00f3n de martensita. Cuando el acero para herramientas se calienta a su temperatura de austenizaci\u00f3n, su estructura se transforma en austenita. Durante el enfriamiento, el acero debe evitar la formaci\u00f3n de estructuras m\u00e1s blandas como perlita o bainita. Si la velocidad de enfriamiento es suficientemente alta, la austenita se transforma en martensita.\n      <\/p>\n\n      <p>\n        Los aceros al carbono simples necesitan una alta velocidad cr\u00edtica de enfriamiento. Deben enfriarse muy r\u00e1pidamente para evitar la formaci\u00f3n de perlita, por lo que <a href=\"https:\/\/aobosteel.com\/es\/w1-tool-steel-heat-treatment\/\">aceros de temple en agua<\/a> necesitan un temple severo.\n      <\/p>\n\n      <p>\n        Los aceros para herramientas de temple al aire tienen una velocidad cr\u00edtica de enfriamiento m\u00e1s baja. Elementos de aleaci\u00f3n como cromo, molibdeno, manganeso, vanadio y tungsteno retrasan la transformaci\u00f3n de austenita en perlita o bainita. Esto da al acero suficiente tiempo para alcanzar el rango de transformaci\u00f3n martens\u00edtica durante un enfriamiento m\u00e1s lento.\n      <\/p>\n\n      <p>\n        Como resultado, el enfriamiento al aire o con gas a\u00fan puede producir martensita. El acero se endurece, pero la tensi\u00f3n de temple es mucho menor que en el temple en agua o aceite.\n      <\/p>\n\n      <h2>Por qu\u00e9 el temple al aire reduce la distorsi\u00f3n y el agrietamiento<\/h2>\n\n      <p>\n        La distorsi\u00f3n proviene principalmente del enfriamiento desigual y la transformaci\u00f3n desigual.\n      <\/p>\n\n      <p>\n        En el temple en agua o aceite, la superficie se enfr\u00eda mucho m\u00e1s r\u00e1pido que el n\u00facleo. La superficie se contrae primero, mientras el interior permanece caliente y expandido. Esto crea tensi\u00f3n t\u00e9rmica. Si la tensi\u00f3n se vuelve demasiado alta, la herramienta puede deformarse o agrietarse.\n      <\/p>\n\n      <p>\n        La formaci\u00f3n de martensita tambi\u00e9n crea tensi\u00f3n porque el acero se expande durante la transformaci\u00f3n. En un temple severo, la superficie puede convertirse en martensita dura mientras el n\u00facleo a\u00fan es austenita caliente. Cuando el n\u00facleo se transforma y expande despu\u00e9s, empuja contra la superficie ya endurecida. Esto puede causar agrietamiento o distorsi\u00f3n severa.\n      <\/p>\n\n      <p>\n        El temple al aire reduce este problema. La superficie y el n\u00facleo se enfr\u00edan de manera m\u00e1s uniforme. La diferencia de temperatura dentro de la herramienta disminuye. La transformaci\u00f3n martens\u00edtica tambi\u00e9n ocurre de manera m\u00e1s uniforme en toda la secci\u00f3n. Esto da a los aceros para herramientas de temple al aire mejor estabilidad dimensional y mayor seguridad durante el temple.\n      <\/p>\n\n      <h2>Acero para herramientas de temple al aire vs temple en aceite vs temple en agua<\/h2>\n\n      <p>\n        Los aceros para herramientas de temple en agua, temple en aceite y temple al aire difieren principalmente en contenido de aleaci\u00f3n, templabilidad, severidad del temple y estabilidad dimensional.\n      <\/p>\n\n      <div class=\"aobo-table-wrap\">\n        <table class=\"aobo-table\">\n          <thead>\n            <tr>\n              <th>Tipo de acero para herramientas<\/th>\n              <th>Grados t\u00edpicos<\/th>\n              <th>Medio de temple<\/th>\n              <th>Ventaja principal<\/th>\n              <th>Limitaci\u00f3n principal<\/th>\n            <\/tr>\n          <\/thead>\n          <tbody>\n            <tr>\n              <td>Acero para herramientas de temple en agua<\/td>\n              <td>W1, W2, W5<\/td>\n              <td>Agua o salmuera<\/td>\n              <td>Bajo costo de aleaci\u00f3n y buena maquinabilidad<\/td>\n              <td>Mayor riesgo de distorsi\u00f3n y agrietamiento<\/td>\n            <\/tr>\n            <tr>\n              <td>Acero para herramientas de temple en aceite<\/td>\n              <td>O1, O2, O6, O7<\/td>\n              <td>Aceite<\/td>\n              <td>Mejor templabilidad que los aceros de la serie W<\/td>\n              <td>A\u00fan tiene riesgo de distorsi\u00f3n por temple l\u00edquido<\/td>\n            <\/tr>\n            <tr>\n              <td>Acero para herramientas de temple al aire<\/td>\n              <td>A2, A6, D2, H13, S7, M2<\/td>\n              <td>Aire, aire forzado, gas o enfriamiento controlado<\/td>\n              <td>Mejor estabilidad dimensional y menor riesgo de agrietamiento por temple<\/td>\n              <td>Mayor costo de aleaci\u00f3n y menor maquinabilidad<\/td>\n            <\/tr>\n          <\/tbody>\n        <\/table>\n      <\/div>\n\n      <p>\n        Los aceros de temple al aire generalmente se seleccionan cuando la estabilidad dimensional, el temple profundo o un menor riesgo de agrietamiento importan m\u00e1s que el costo de la materia prima.\n      <\/p>\n\n      <h2>Grados comunes de acero para herramientas de temple al aire<\/h2>\n\n      <p>\n        Los aceros para herramientas de temple al aire no se limitan a un grupo AISI.

A2, D2, H13, S7 y M2 no comparten un mismo programa de tratamiento t\u00e9rmico. Un acero de trabajo en fr\u00edo, un acero de trabajo en caliente y un acero r\u00e1pido requieren condiciones diferentes de temple y revenido.\n      <\/p>\n\n      <p>\n        La protecci\u00f3n de la superficie tambi\u00e9n es importante. Muchos grados de temple al aire utilizan temperaturas de austenizaci\u00f3n elevadas. Una atm\u00f3sfera deficiente del horno puede causar descarburizaci\u00f3n, dejando una capa superficial blanda. Los hornos de vac\u00edo, las atm\u00f3sferas controladas, los ba\u00f1os de sal o los m\u00e9todos de envoltura adecuados ayudan a reducir este riesgo.\n      <\/p>\n\n      <p>\n        La austenita retenida tambi\u00e9n puede afectar la estabilidad dimensional. Un alto contenido de aleaci\u00f3n puede dejar austenita inestable despu\u00e9s del temple.

El alto contenido de aleaci\u00f3n y los carburos duros hacen que muchos aceros de temple al aire sean m\u00e1s dif\u00edciles de mecanizar y rectificar. Los aceros de la serie A suelen ser menos mecanizables que los aceros de temple en agua. El D2 es m\u00e1s dif\u00edcil debido a su alto volumen de carburos.\n      <\/p>\n\n      <p>\n        La segunda limitaci\u00f3n es el costo. El cromo, molibdeno, vanadio, tungsteno y otros elementos de aleaci\u00f3n aumentan el costo de la materia prima. Los grados de temple al aire suelen costar m\u00e1s que los aceros simples de la serie W o de la serie O.\n      <\/p>\n\n      <p>\n        La tercera limitaci\u00f3n es el tama\u00f1o de secci\u00f3n. Los aceros de temple al aire son de temple profundo, pero el aire todav\u00eda tiene l\u00edmites. Las secciones muy grandes pueden requerir aire forzado, temple con gas u otro m\u00e9todo de enfriamiento controlado. La elecci\u00f3n correcta depende del grado, el tama\u00f1o, la geometr\u00eda y la capacidad del horno.\n      <\/p>\n\n      <p>\n        La normalizaci\u00f3n generalmente no es adecuada para los aceros de herramienta de temple al aire. El enfriamiento al aire desde alta temperatura puede endurecer el acero a martensita fr\u00e1gil. Cuando se necesita ablandamiento, estos aceros normalmente requieren recocido completo en lugar de normalizaci\u00f3n.\n      <\/p>\n\n      <p>\n        El temple al aire tampoco significa distorsi\u00f3n cero. El calentamiento deficiente, el espesor de secci\u00f3n desigual, el enfriamiento inadecuado, el revenido retrasado o el control deficiente del horno a\u00fan pueden causar grietas, cambios dimensionales o reducci\u00f3n de la vida \u00fatil de la herramienta.\n      <\/p>\n\n    <\/main>\n\n    <section class=\"aobo-final-cta\">\n      <h2>\u00bfNecesita suministro de acero para herramientas de temple al aire en grandes cantidades?<\/h2>\n      <p>\n        Aobo Steel suministra barras redondas y barras planas de acero para herramientas para pedidos al por mayor.
