Se utiliza ampliamente en herramientas neum\u00e1ticas, cinceles, punzones, cuchillas de corte y matrices de conformado. Este acero contiene aproximadamente 0,501 TP3T de carbono, 2,501 TP3T de tungsteno y 1,501 TP3T de cromo. Ofrece una combinaci\u00f3n equilibrada de resistencia, resistencia al desgaste y templabilidad, con una resistencia moderada al ablandamiento a temperaturas elevadas. Su mayor ventaja reside en su excepcional resistencia transversal y su excelente resistencia al astillamiento bajo cargas de impacto.&nbsp;<\/p>\n\n\n\n<p>En Aobo Steel, suministramos acero S1 en estado revenido. Los procesos de tratamiento t\u00e9rmico que nuestros clientes utilizan para el acero para herramientas S1 incluyen tratamientos de alivio de tensiones y temple.

Temple de grietas.&nbsp;<\/h3>\n\n\n\n<p>Este defecto se debe principalmente a dos causas: primero, el revenido retardado (no realizar el revenido r\u00e1pidamente despu\u00e9s del temple, lo que resulta en una exposici\u00f3n prolongada a temperatura ambiente y genera tensiones que superan la resistencia del material); segundo, los puntos de concentraci\u00f3n de tensiones en las piezas S1, como esquinas afiladas, marcas de estampado o mecanizado de desbaste. Para solucionar estos problemas, se debe implementar un revenido inmediato: transferir la pieza al horno de revenido mientras retiene el calor residual (aproximadamente 50-70 \u00b0C). Simult\u00e1neamente, durante las etapas de dise\u00f1o y mecanizado, se deben emplear esquinas redondeadas en las uniones cr\u00edticas y mantener las superficies con un acabado superficial de alta calidad.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-low-hardness-nbsp\">2. Baja dureza.&nbsp;<\/h3>\n\n\n\n<p>Las causas principales de este defecto incluyen: p\u00e9rdida de carbono superficial (descarburaci\u00f3n) debido a una atm\u00f3sfera inadecuada durante la austenizaci\u00f3n; temperatura de calentamiento o tiempo de mantenimiento insuficientes durante la austenizaci\u00f3n; y severidad de enfriamiento inadecuada causada por una temperatura del aceite excesivamente alta o una agitaci\u00f3n insuficiente durante el enfriamiento.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-3-deformation-nbsp\">3. Deformaci\u00f3n.&nbsp;<\/h3>\n\n\n\n<p>La deformaci\u00f3n suele ser consecuencia de un choque t\u00e9rmico causado por una expansi\u00f3n desigual debido a velocidades de calentamiento excesivas o por las tensiones residuales generadas durante el mecanizado de desbaste, que se liberan durante el calentamiento. Las medidas preventivas incluyen: precalentar a 650 \u00b0C antes del temple; aplicar un tratamiento de alivio de tensiones a las piezas mecanizadas de desbaste antes del temple; y proporcionar soporte f\u00edsico a las piezas largas o complejas para evitar el descuelgue.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-4-soft-layer-decarbonization-nbsp\">4. Capa blanda (descarbonizaci\u00f3n).&nbsp;<\/h3>\n\n\n\n<p id=\"h-\">Este defecto se produce cuando el ox\u00edgeno o la humedad del horno reaccionan con el carbono superficial, produciendo di\u00f3xido de carbono o mon\u00f3xido de carbono que se escapan, reduciendo as\u00ed el contenido de carbono. Puede comprobarlo con una lima. Si raya f\u00e1cilmente la superficie, indica la presencia de una capa blanda. Para evitar estos problemas, se pueden tomar las siguientes medidas: utilizar hornos de vac\u00edo o de atm\u00f3sfera protectora llenos de gases inertes (como nitr\u00f3geno o arg\u00f3n) para aislar el ox\u00edgeno; al utilizar un horno de ba\u00f1o de sal para calentar, la salmuera debe calibrarse peri\u00f3dicamente para garantizar que se mantenga neutra y no reaccione con el carbono; antes del tratamiento t\u00e9rmico S1, deje suficiente tolerancia para garantizar que esta capa descarburada pueda eliminarse por completo mediante rectificado de precisi\u00f3n despu\u00e9s del tratamiento t\u00e9rmico.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-faq\">Preguntas frecuentes<\/h2>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1768368514600\"><strong class=\"schema-faq-question\">\u00bfCu\u00e1l es la temperatura de endurecimiento del acero para herramientas S1?<\/strong> <p class=\"schema-faq-answer\">La temperatura de calentamiento para la austenizaci\u00f3n debe estar entre 900 \u00b0C y 955 \u00b0C (1650 \u00b0F y 1750 \u00b0F).
