Sin embargo, para una dureza dada, puede variar ampliamente seg\u00fan el <a href=\"https:\/\/aobosteel.com\/es\/tool-steel-wear-mechanisms\/\">mecanismo de desgaste<\/a> y el tratamiento t\u00e9rmico utilizado. Aceros con dureza similar pueden comportarse de manera muy diferente bajo condiciones de desgaste id\u00e9nticas. Los grados que mejor resisten el desgaste tambi\u00e9n son los m\u00e1s dif\u00edciles de mecanizar, y el <a href=\"\/es\/tool-steel-machinability-rating-chart\/\">tabla de calificaci\u00f3n de maquinabilidad<\/a> cuantifica ese compromiso.<\/p>\n\n\n\n<h2 id=\"h-toughness-amp-testing\" class=\"wp-block-heading\">Resistencia y pruebas<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A m\u00e1xima dureza, la mayor\u00eda de los aceros para herramientas son fr\u00e1giles, por lo que los ensayos de tracci\u00f3n rara vez proporcionan valores de resistencia confiables. Los ensayos de compresi\u00f3n, flexi\u00f3n y torsi\u00f3n son m\u00e1s \u00fatiles; el ensayo de impacto por torsi\u00f3n proporciona datos reproducibles sobre el efecto de la composici\u00f3n y el tratamiento t\u00e9rmico, particularmente para brocas y herramientas cargadas en torsi\u00f3n. Cuando la tenacidad y la resistencia al desgaste tiran en direcciones opuestas, <a href=\"\/es\/tool-steel-selection-by-application\/\">selecci\u00f3n por aplicaci\u00f3n<\/a> es la v\u00eda m\u00e1s r\u00e1pida hacia un grado.<\/p>\n\n\n\n<h2 id=\"h-supply-scope-amp-technical-reference-note\" class=\"wp-block-heading\">Nota sobre el alcance del suministro y la referencia t\u00e9cnica<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Aobo Steel suministra acero para herramientas recocido en forma de barra redonda y placa. La instalaci\u00f3n de tratamiento t\u00e9rmico del cliente realiza el endurecimiento, el temple y el revenido. La gu\u00eda de tratamiento t\u00e9rmico del acero para herramientas cubre las temperaturas de austenizaci\u00f3n, los tiempos de permanencia y las ventanas de revenido para estos grados.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Las calificaciones de propiedades y los datos de dureza de esta referencia son comparaciones relativas recopiladas del ASM Handbook, Volumen 1, Tabla 13. El rendimiento real depende del tratamiento t\u00e9rmico, el tama\u00f1o de secci\u00f3n, la geometr\u00eda de la herramienta y las condiciones de servicio.
