This alloy design gives them higher hardenability than plain water-hardening tool steels. As a result, they can achieve higher hardness with oil quenching rather than water quenching.\n      <\/p>\n      <p>\n        Oil-hardening tool steels sit between water-hardening steels and air-hardening steels. They are safer to harden than water-hardening steels because oil quenching reduces cracking and distortion. Compared with air-hardening steels, they are usually easier to machine and more economical, but they typically offer lower dimensional stability and wear resistance under severe tooling conditions.\n      <\/p>\n      <p>\n        Their best use is in cold-work tooling that requires balanced hardness, wear resistance, machinability, heat-treatment safety, and cost-effectiveness. Their main limitation is poor resistance to softening at elevated temperatures. For hot-work dies, die-casting tools, or high-speed cutting tools, hot-work steels or high-speed steels are more suitable.\n      <\/p>\n\n      <h2>Acero para herramientas endurecible al aceite frente a acero endurecible al agua y al aire.<\/h2>\n      <p>\n        El acero para herramientas de endurecimiento en aceite se comprende mejor compar\u00e1ndolo con los dos grupos vecinos de aceros para herramientas de trabajo en fr\u00edo: los aceros de endurecimiento en agua y los aceros de endurecimiento en aire.\n      <\/p>\n\n      <div class=\"aobo-table-wrap\">\n        <table class=\"aobo-table\">\n          <thead>\n            <tr>\n              <th>Art\u00edculo<\/th>\n              <th>Acero para herramientas endurecible por agua<\/th>\n              <th>Acero para herramientas endurecible al aceite<\/th>\n              <th>Acero para herramientas de endurecimiento al aire<\/th>\n            <\/tr>\n          <\/thead>\n          <tbody>\n            <tr>\n              <td>Calificaciones t\u00edpicas<\/td>\n              <td>W1, W2<\/td>\n              <td>O1, O2, O6, O7<\/td>\n              <td>A2, A6, A7, A10<\/td>\n            <\/tr>\n            <tr>\n              <td>M\u00e9todo de enfriamiento<\/td>\n              <td>Agua o salmuera<\/td>\n              <td>Aceite<\/td>\n              <td>Refrigeraci\u00f3n por aire o controlada<\/td>\n            <\/tr>\n            <tr>\n              <td>Contenido de aleaci\u00f3n<\/td>\n              <td>Bajo<\/td>\n              <td>Moderado<\/td>\n              <td>M\u00e1s alto<\/td>\n            <\/tr>\n            <tr>\n              <td>Templabilidad<\/td>\n              <td>Bajo<\/td>\n              <td>Medio<\/td>\n              <td>Alta<\/td>\n            <\/tr>\n            <tr>\n              <td>Riesgo de distorsi\u00f3n<\/td>\n              <td>Alta<\/td>\n              <td>Medio<\/td>\n              <td>Bajo<\/td>\n            <\/tr>\n            <tr>\n              <td>Riesgo de agrietamiento<\/td>\n              <td>Alta<\/td>\n              <td>Inferior a la serie W<\/td>\n              <td>Generalmente el m\u00e1s bajo entre estos grupos.<\/td>\n            <\/tr>\n            <tr>\n              <td>Maquinabilidad<\/td>\n              <td>Muy bien<\/td>\n              <td>Bien<\/td>\n              <td>Generalmente m\u00e1s bajo<\/td>\n            <\/tr>\n            <tr>\n              <td>Resistencia al desgaste<\/td>\n              <td>Moderado<\/td>\n              <td>Bien<\/td>\n              <td>Generalmente m\u00e1s alto<\/td>\n            <\/tr>\n            <tr>\n              <td>Coste<\/td>\n              <td>Generalmente el m\u00e1s bajo<\/td>\n              <td>Econ\u00f3mico<\/td>\n              <td>Generalmente m\u00e1s alto<\/td>\n            <\/tr>\n            <tr>\n              <td>Mejor uso<\/td>\n              <td>Herramientas sencillas y aplicaciones de bajo coste<\/td>\n              <td>Herramientas generales para trabajos en fr\u00edo que requieren un endurecimiento m\u00e1s seguro.<\/td>\n              <td>Herramientas complejas, series largas y un control dimensional m\u00e1s estricto.<\/td>\n            <\/tr>\n          <\/tbody>\n        <\/table>\n      <\/div>\n\n      <p>\n        Los aceros de temple en agua son sencillos y econ\u00f3micos, pero su temple severo los hace riesgosos para herramientas complejas.

El acero O7 mejora a\u00fan m\u00e1s la resistencia al desgaste gracias a su mayor contenido de carbono y tungsteno.

During annealing, part of its carbon forms free nodular graphite.

O2 can harden at a relatively low temperature, which helps reduce heat-treatment movement. O7 needs closer quenching control because its higher carbon and tungsten improve wear resistance but reduce hardenability in thicker sections. In thicker O7 tools, oil temperature, agitation, and transfer time become more critical.\n      <\/p>\n      <p>\n        Oil agitation matters during quenching. Without sufficient oil movement, vapor can form around the hot tool, and cooling can slow and become uneven. This may cause soft spots or uneven hardness.\n      <\/p>\n      <p>\n        Tempering should follow quenching promptly. As-quenched steel is hard but brittle, and tempering imparts usable toughness to the tool. For many O-series cold-work tools, the final hardness is typically around 58 to 62 HRC, but the required hardness should be determined by the tool design and service conditions.\n      <\/p>\n\n      <h2>C\u00f3mo elegir el grado adecuado de acero para herramientas endurecible al aceite<\/h2>\n      <p>\n        La selecci\u00f3n del grado debe partir del problema principal de funcionamiento de la herramienta.\n      <\/p>\n\n      <div class=\"aobo-table-wrap\">\n        <table class=\"aobo-table\">\n          <thead>\n            <tr>\n              <th>Requisito principal<\/th>\n              <th>Grado recomendado<\/th>\n              <th>Raz\u00f3n<\/th>\n            <\/tr>\n          <\/thead>\n          <tbody>\n            <tr>\n              <td>Herramientas de trabajo en fr\u00edo de uso general<\/td>\n              <td>O1<\/td>\n              <td>Propiedades equilibradas y amplia disponibilidad comercial.<\/td>\n            <\/tr>\n            <tr>\n              <td>M\u00ednima distorsi\u00f3n durante el endurecimiento<\/td>\n              <td>O2<\/td>\n              <td>Una temperatura de austenizaci\u00f3n m\u00e1s baja reduce las tensiones del tratamiento t\u00e9rmico.<\/td>\n            <\/tr>\n            <tr>\n              <td>Alta maquinabilidad y resistencia al desgaste<\/td>\n              <td>O6<\/td>\n              <td>El grafito libre act\u00faa como lubricante s\u00f3lido, mejorando el corte y evitando el agarrotamiento.<\/td>\n            <\/tr>\n            <tr>\n              <td>M\u00e1xima resistencia al desgaste y retenci\u00f3n del filo.<\/td>\n              <td>O7<\/td>\n              <td>Un mayor contenido de carbono y tungsteno forma carburos duros y resistentes a la abrasi\u00f3n.<\/td>\n            <\/tr>\n            <tr>\n              <td>Herramientas de tolerancia estricta y calibres de precisi\u00f3n<\/td>\n              <td>O2<\/td>\n              <td>Mejor control dimensional para dise\u00f1os de tolerancia ajustada.<\/td>\n            <\/tr>\n          <\/tbody>\n        <\/table>\n      <\/div>\n\n      <p>\n        For most general tooling, O1 is the starting point.

The main grades are O1, O2, O6, and O7. These steels harden in oil because their moderate alloy content gives them better hardenability than plain water-hardening steels.\n      <\/p>\n      <p>\n        O-series steels are widely used for blanking dies, trimming dies, forming dies, drawing dies, punches, gauges, cutting tools, and precision machine parts. Their main advantages are good machinability, useful wear resistance, safer hardening than water-hardening steel, and economical tool production.\n      <\/p>\n      <p>\n        They also have clear limits. They do not resist high-temperature softening well, and they cannot match air-hardening steels in dimensional stability or D2-type steels in severe wear resistance.\n      <\/p>\n      <p>\n        For cold-work tools that require balanced performance, controlled heat-treatment risk, and reasonable cost, oil-hardening tool steel remains a practical and widely used choice.\n      <\/p>\n\n    <\/main>\n\n    <section class=\"aobo-final-cta\">\n      <div>\n        <h2>\u00bfNecesita suministro a granel de acero para herramientas endurecible al aceite?<\/h2>\n        <p>\n          Aobo Steel suministra barras redondas y planas de acero para herramientas O1, O2 y otros tipos para pedidos industriales a granel.
