class=\"wp-block-heading\">Propiedades mec\u00e1nicas del acero para herramientas Cr12<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">El acero Cr12 se clasifica como un acero ledebur\u00edtico con alto contenido de carbono y cromo. Debido a su alta fracci\u00f3n de masa de carbono, presenta una menor tenacidad al impacto y una tendencia a la fractura fr\u00e1gil, adem\u00e1s de una susceptibilidad a la formaci\u00f3n de carburos eut\u00e9cticos no uniformes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La alta concentraci\u00f3n de cromo en el acero favorece la formaci\u00f3n de carburos complejos (CrFe)\u2087C\u2083, lo que a su vez reduce la cantidad de cementita (Fe\u2083C). Durante el temple, una fracci\u00f3n significativa de estos carburos se disuelve en la fase austen\u00edtica. El temple posterior transforma la austenita en martensita de alta dureza. Tras el revenido, se produce una precipitaci\u00f3n fina y dispersa de carburos dentro de la matriz martens\u00edtica, lo que resulta en una excelente resistencia al desgaste.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mediante un proceso de tratamiento t\u00e9rmico adecuado, se puede lograr una microestructura que combine alta resistencia y tenacidad.<\/p>\n\n\n\n<h2 id=\"h-cr12-tool-steel-forging-process\" class=\"wp-block-heading\">Proceso de forjado del acero para herramientas Cr12<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Art\u00edculo<\/strong><\/td><td><strong>Temperatura de calentamiento\/\u00b0C<\/strong><\/td><td><strong>Temperatura inicial de forjado\/\u00b0C<\/strong><\/td><td><strong>Temperatura final de forjado\/\u00b0C<\/strong><\/td><td><strong>M\u00e9todo de enfriamiento<\/strong><\/td><\/tr><tr><td>Lingote de acero<\/td><td>1140 ~ 1160<\/td><td>1100 ~ 1120<\/td><td>900 ~ 920<\/td><td>Enfriamiento lento<\/td><\/tr><tr><td>Lingote de acero<\/td><td>1120 ~ 1140<\/td><td>1080 ~ 1100<\/td><td>880 ~ 920<\/td><td>Enfriamiento lento<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">El objetivo principal del forjado del acero Cr12 es descomponer y refinar los carburos gruesos inherentes al acero, asegurando su distribuci\u00f3n uniforme en toda la matriz. Este proceso mejora significativamente la resistencia y tenacidad generales del material. Adem\u00e1s, un forjado adecuado establece una alineaci\u00f3n racional de las l\u00edneas de flujo dentro del molde, lo que contribuye a generar cambios dimensionales (distorsi\u00f3n) consistentes y predecibles en todas las direcciones durante el posterior temple.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En cuanto al proceso de calentamiento para el forjado, es fundamental precalentar la pieza antes de aumentar gradualmente su temperatura hasta alcanzar la temperatura final. Se debe prestar atenci\u00f3n a la correcta colocaci\u00f3n de la pieza dentro del horno, y girarla o voltearla peri\u00f3dicamente para asegurar un calentamiento uniforme.<\/p>\n\n\n\n<h2 id=\"h-cr12-tool-steel-heat-treatment\" class=\"wp-block-heading\">Tratamiento t\u00e9rmico del acero para herramientas Cr12<\/h2>\n\n\n\n<h3 id=\"h-preheating\" class=\"wp-block-heading\">Precalentamiento<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><\/td><td><strong>Par\u00e1metros del proceso<\/strong><\/td><\/tr><tr><td><strong>Recocido general despu\u00e9s del forjado<\/strong><\/td><td>Temperatura de calentamiento: 850 ~ 870 \u00b0C.
