Tratamiento t\u00e9rmico del acero para herramientas M4<\/h1>\n\n\n\n

La composici\u00f3n qu\u00edmica, el ciclo de temple y la l\u00ednea de revenido que la ficha de origen indica para el acero r\u00e1pido al molibdeno M4. Un resumen de referencia de la pr\u00e1ctica publicada y no una especificaci\u00f3n de Aobo Steel.<\/p>\n\n\n\n

M4 en el grupo de aceros r\u00e1pidos al molibdeno<\/h2>\n\n\n\n

El M4 se sit\u00faa en el grupo de aceros r\u00e1pidos al molibdeno de la serie M, y es el vanadio lo que lo distingue del M2 y del M7. La ficha de la que provienen estas tablas indica 4,00% de vanadio, 1,30% de carbono, 4,50% de molibdeno y 5,50% de tungsteno, con cromo al 4,00% y azufre al 0,27%. El cobalto aparece en la ficha sin ninguna cifra asociada. Las tres tablas siguientes reproducen lo que indica la ficha y nada m\u00e1s, y cada cifra de composici\u00f3n qu\u00edmica se verifica contra los rangos que la tabla de composici\u00f3n de este sitio indica para el grado.<\/p>\n\n\n\n

La ficha es informaci\u00f3n de referencia de taller m\u00e1s que una especificaci\u00f3n. Indica una temperatura de precalentamiento, una temperatura de temple y dos medios de enfriamiento, luego una tabla de revenido con una sola cifra de dureza en cada fila y sin banda de tolerancia en ninguna parte. Conviene tratar una primera tanda de piezas de una nueva colada de acero como una prueba antes de que el ciclo pase a trabajos de producci\u00f3n.<\/p>\n\n\n\n

La ficha indica una sola cifra para cada elemento en lugar de un rango de especificaci\u00f3n. El cobalto aparece en la ficha sin ninguna cifra asociada, por lo que esa fila se omite de la tabla en lugar de imprimirse en blanco. El azufre al 0,27% es la cifra que la ficha indica para el grado.<\/em><\/p>\n\n\n\n

El carbono al 1,30% y el vanadio al 4,00% son las dos cifras que distinguen al M4 dentro del grupo de aceros r\u00e1pidos al molibdeno, y la ficha las indica como valores \u00fanicos en lugar de rangos. Cada cifra de la ficha cae dentro del rango que la tabla de composici\u00f3n de este sitio indica para el M4, UNS T11304, que va de 1,25 a 1,40% de carbono, 3,75 a 4,75% de cromo, 4,25 a 5,50% de molibdeno, 5,25 a 6,50% de tungsteno y 3,75 a 4,50% de vanadio. La misma tabla sit\u00faa el vanadio del M2 en 1,75 a 2,20% y el vanadio del M7 en 1,75 a 2,25%, por lo que el 4,00% de esta ficha es aproximadamente el doble de lo que llevan esos dos grados de acero r\u00e1pido al molibdeno, y la tabla de revenido de este sitio lista el tipo para el M4 como acero r\u00e1pido al molibdeno, al vanadio. El azufre se indica en la ficha y no en la tabla de composici\u00f3n, y el cobalto no lleva ninguna cifra asociada. Los datos de composici\u00f3n de la tabla son solo de referencia general, los valores reales var\u00edan seg\u00fan la norma, la acer\u00eda y el n\u00famero de colada, por lo que conviene confirmar las cifras contra el certificado de ensayo del material de la colada o consultar a Aobo Steel.<\/p>\n\n\n\n

La ficha indica una temperatura de precalentamiento, una temperatura de temple y dos medios de enfriamiento para el grado, sin ninguna condici\u00f3n de tama\u00f1o de secci\u00f3n asociada a ninguno de ellos, por lo que las cifras rigen para la carga tal como est\u00e1 escrita. La tabla de temperaturas de temple y revenido de este sitio da al grupo M3 y M4 una ventana de temple de 2200 a 2250 \u00b0F (1205 a 1230 \u00b0C) y lista aceite, aire o sal como medios de enfriamiento, por lo que la \u00fanica cifra de esta ficha cae dentro de esa ventana y los dos medios que indica son dos de los tres que permite la tabla.<\/em><\/p>\n\n\n\n

El precalentamiento de 1500 \u00b0F (815 \u00b0C) cae dentro de la banda de precalentamiento de 1350 a 1550 \u00b0F que la tabla de temple y revenido de este sitio indica para el grupo M3 y M4, y la ficha no indica ninguna condici\u00f3n asociada, por lo que el paso rige para toda carga. El temple se realiza a 2225 \u00b0F (1220 \u00b0C) en aceite o sal. La misma tabla da al grupo una ventana de 2200 a 2250 \u00b0F (1205 a 1230 \u00b0C) y lista aceite, aire o sal como medios de enfriamiento, por lo que la \u00fanica cifra de temple de esta ficha cae dentro de esa ventana y los dos medios que indica la ficha son dos de los tres que permite la tabla. La ficha no elige entre aceite y sal, por lo que esa elecci\u00f3n queda en manos del taller y de la secci\u00f3n que se trata.<\/p>\n\n\n\n

La ficha indica una sola cifra Rockwell C en cada fila. Esta ficha lleva una cifra en la fila reci\u00e9n templada (sin revenir), 64 HRC, por lo que esa fila se muestra sin temperatura de revenido asociada. La l\u00ednea baja a 62 HRC a 900 \u00b0F (480 \u00b0C) antes de subir a su pico de 66 HRC a 950 \u00b0F (510 \u00b0C), y desciende a 58 HRC en el extremo de 1200 \u00b0F (650 \u00b0C) de la tabla. La ficha no dice nada sobre el n\u00famero de ciclos de revenido.<\/em><\/p>\n\n\n\n

Esta ficha lleva una cifra en la fila reci\u00e9n templada (sin revenir), 64 HRC, por lo que la tabla comienza ah\u00ed. La l\u00ednea baja a 62 HRC a 900 \u00b0F (480 \u00b0C), sube a su pico de 66 HRC a 950 \u00b0F (510 \u00b0C), mantiene 65 HRC en 1000 y 1050 \u00b0F (540 y 565 \u00b0C), y cae a 58 HRC a 1200 \u00b0F (650 \u00b0C), por lo que la respuesta alcanza su pico un poco por encima de 950 \u00b0F y no vuelve a subir en la parte alta de la tabla. En la banda de 1000 a 1100 \u00b0F donde la tabla de revenido de este sitio recomienda revenir el M4, esa tabla lista 66 a 61 HRC y la ficha indica 65, 65 y 64, dentro de esa banda. La ficha no dice nada sobre el n\u00famero de ciclos de revenido, por lo que conviene tratar la l\u00ednea como la respuesta del grado y definir los ciclos con su tratador t\u00e9rmico antes de que las piezas entren en servicio.<\/p>\n\n\n\n
