Abstract

La presente invención se refiere a un procedimiento para fabricar un artículo de hierro ductil austemplado que tiene porciones seleccionadas del mismo endurecidas y otras porciones no endurecidas, que consiste de: fundir un artículo de una composición de hierro fundido que incluye en peso de 3.40 por ciento a 3.90 por ciento de carbono, de 1.90 por ciento a 2.70 por ciento de silicio, hasta 1.40 por ciento de manganeso, hasta 1.5 por ciento de molibdeno, hasta 0.08 por ciento de fósforo, hasta 2.0 por ciento de cobre y siendo el resto hierro; y austenitizar las porciones seleccionadas solamente del artículo en una condición no austemplada a una primera temperatura dentro de la escala de 771 grados C. a 1149 grados C., durante un período de un segundo a 100 segundos; enfriar rápidamente el artículo hasta una segunda temperatura de 232 grados C. a 454 grados C., dentro de 180 segundos; templar el artículo a la segunda temperatura durante un período de 10 minutos a 240 minutos; y enfriar el artículo a temperatura ambiente, mediante lo cual se forma en las porciones seleccionadas del artículo una capa de hierro ductil austemplado.
