Tabla de tiempo de colores de revenido para acero para herramientas<\/h1>\n\n\n\n

Minutos a temperatura constante antes de que una pieza de acero pulida alcance el color paja, marr\u00f3n, p\u00farpura, azul oscuro y azul p\u00e1lido, seg\u00fan ensayos publicados en 1910. Resumen de referencia de la pr\u00e1ctica publicada y no una especificaci\u00f3n de Aobo Steel.<\/p>\n\n\n\n

Qu\u00e9 miden las cifras<\/h2>\n\n\n\n

Esta es una tabla de tiempo y no una tabla de temperatura. Piezas similares de acero se mantuvieron al aire, a una temperatura fija para cada ensayo, y los minutos registrados son los necesarios para llevar la superficie al color completo indicado en la parte superior de la columna. Un color de revenido es una pel\u00edcula de \u00f3xido sobre acero pulido, y la pel\u00edcula sigue engrosando mientras la pieza permanece caliente, por lo que el color avanza incluso cuando la temperatura nunca cambia.<\/p>\n\n\n\n

Los ensayos se realizaron con libre acceso de aire. Los resultados se reproducen en The Heat Treatment of Tool Steel, escrito por Harry Brearley en 1910 para talleres de herramientas y matrices, en la misma p\u00e1gina que registra el descubrimiento detr\u00e1s del h\u00e1bito del color de revenido, que el color proviene de la oxidaci\u00f3n superficial y no solo de la temperatura.<\/p>\n\n\n\n

Minutos para alcanzar cada color de revenido<\/h2>\n\n\n\n

Minutos a una temperatura antes de que aparezca el color completo en una pieza pulida calentada al aire. Un guion significa que la fuente no da cifra para ese par. El medio minuto a 275 grados C est\u00e1 impreso como fracci\u00f3n en la fuente. Las piezas ensayadas eran de tama\u00f1o similar, por lo que los tiempos escalan con el tama\u00f1o de secci\u00f3n y con la atm\u00f3sfera del horno.<\/em><\/p>\n\n\n\n

Lea primero las columnas<\/h2>\n\n\n\n

Cada color llega antes a medida que sube la temperatura. El paja tarda 6 minutos a 200 grados C y medio minuto a 275. El marr\u00f3n tarda 49 minutos a 200 y 3 minutos a 275. El p\u00farpura no aparece a 200 en estos ensayos en absoluto, necesita 63 minutos a 220 y llega en 11 minutos a 275. El azul oscuro y el azul p\u00e1lido solo se alcanzan en el ensayo m\u00e1s caliente, a los 27 y 40 minutos.<\/p>\n\n\n\n

El intervalo entre el primer color y el \u00faltimo es lo que importa en el banco. A 275 grados C una pieza pasa de paja a azul p\u00e1lido en 40 minutos. A 220 grados C tarda una hora en pasar de paja a p\u00farpura, y los dos colores m\u00e1s calientes nunca se alcanzan. Leer un color es por lo tanto una verificaci\u00f3n de cu\u00e1nto tiempo ha estado caliente la pieza tanto como de cu\u00e1n caliente est\u00e1, y los dos no pueden separarse a simple vista.<\/p>\n\n\n\n

El mismo color no es el mismo revenido<\/h2>\n\n\n\n

Un tono dado marca una temperatura diferente en un ensayo diferente. La misma p\u00e1gina contiene una demostraci\u00f3n de Turner de que se puede producir un p\u00farpura a 250 grados C en unos pocos minutos, que el mismo p\u00farpura necesita aproximadamente una hora a 220 grados C, y que tarda aproximadamente doce horas a 170 grados C. Tres temperaturas, un color.<\/p>\n\n\n\n

That is why the source concludes that the tempering effect depends on the temperature and is largely independent of time, while the colour is only an empirical guide under definite conditions. On a tool steel the hardness that matters comes from the tempering temperature held for its prescribed time<\/a>, not from the shade on the surface. Colour is a field check for a shop that has no pyrometer, and it is a coarse one, since a polished face colours quickly, a scaled or rough one slowly, and a draught across the part shifts the reading.<\/p>\n\n\n\n

Para trabajos que deben mantener una ventana de dureza, use el programa publicado para el grado. Nuestro Tabla de revenido del acero para herramientas<\/a> da temperaturas de temple y revenido con la dureza resultante, y el gu\u00eda de tratamiento t\u00e9rmico del acero para herramientas<\/a> cubre la secuencia completa desde el recocido hasta el revenido final.<\/p>\n\n\n\n

Donde todav\u00eda se usa el color de revenido<\/h2>\n\n\n\n

El m\u00e9todo del color de \u00f3xido sobrevive en grados simples de carbono y de temple al aceite, donde una pieza peque\u00f1a se reviene en un horno abierto y el operador juzga el acabado a simple vista. acero para herramientas O1<\/a> es el grado habitual para eso, y D2<\/a> es el grado com\u00fan de trabajo en fr\u00edo donde los mismos colores todav\u00eda se ven en una cara pulida despu\u00e9s del revenido. Para cualquier cosa cargada en servicio, la tabla de temperatura contra color es una mejor gu\u00eda que la tabla de tiempo, porque se lee contra el horno y no contra el reloj.<\/p>\n\n\n\n

Datos de referencia relacionados<\/h2>\n\n\n\n

Para la dureza que produce cada temperatura de revenido en un grado espec\u00edfico, consulte el tabla de templado<\/a> y la Tabla de revenido del acero al carbono para herramientas<\/a>.<\/p>\n\n\n\n
