    1. (a) O, temple en aceite; A, enfriamiento al aire; S, temple en ba\u00f1o de sales; W, temple en agua; B, temple en salmuera.<\/li>\n\n
    2. (b) Cuando el calentamiento a alta temperatura se realiza en un ba\u00f1o de sales, el rango de temperaturas debe ser aproximadamente 14 \u00b0C (25 \u00b0F) menor que el indicado aqu\u00ed.<\/li>\n\n
    3. (c) Se recomienda doble revenido durante no menos de 1 h a temperatura cada vez.<\/li>\n\n
    4. (d) Se recomienda triple revenido durante no menos de 1 h a temperatura cada vez.<\/li>\n\n
    5. (e) Los tiempos se aplican al tratamiento t\u00e9rmico en horno abierto. Para el endurecimiento en caja<\/a>, una regla com\u00fan es calentar 1.2 min por mm (30 min por in.) de secci\u00f3n transversal de la caja.<\/li>\n\n
    6. (f) Preferible para herramientas grandes para minimizar la descarburaci\u00f3n.<\/li>\n\n

    8. (h) Despu\u00e9s de la cementaci\u00f3n.<\/li>\n\n
    9. (i) Cementado seg\u00fan la dureza de la capa.<\/li>\n\n
    10. (j) P21 es un acero de endurecimiento por precipitaci\u00f3n cuyo tratamiento t\u00e9rmico implica tratamiento de soluci\u00f3n y envejecimiento en lugar de temple y revenido.<\/li>\n\n
    11. (k) Recomendado para herramientas grandes y herramientas con secciones intrincadas.<\/li>\n<\/ol>\n\n\n\n

      Nota sobre el alcance del suministro y la referencia t\u00e9cnica<\/h3>\n\n\n\n

      Aobo Steel suministra acero para herramientas en estado estado recocido<\/a> y no proporciona servicios finales de tratamiento t\u00e9rmico como temple, enfriamiento, tratamiento criog\u00e9nico o revenido.<\/p>\n\n\n\n

      Los par\u00e1metros de tratamiento t\u00e9rmico, los datos de dureza y las recomendaciones de proceso que se incluyen en esta referencia se proporcionan como asistencia t\u00e9cnica general para nuestros clientes. Los resultados reales del tratamiento t\u00e9rmico pueden variar seg\u00fan la capacidad del horno, el tama\u00f1o de la secci\u00f3n, la geometr\u00eda de la herramienta, el estado del material, la pr\u00e1ctica de temple y el control del proceso. Los procedimientos finales de tratamiento t\u00e9rmico y su validaci\u00f3n deben ser realizados por las instalaciones de tratamiento t\u00e9rmico del cliente, de acuerdo con la aplicaci\u00f3n espec\u00edfica de la herramienta y los requisitos de producci\u00f3n.<\/p>\n\n\n\n
