Abstract

La presente se refiere a una aleación de acero para trabajo en frío para la fabricación pulverometalúrgica de piezas, especialmente herramientas con calidad de uso mejorada. Para ajustar las propiedades características más importantes, resistencia a la rotura por flexión, trabajo de flexión por golpes y resistencia al desgaste, de modo que tenga un nivel elevado de la misma magnitud, de acuerdo con la presente está previsto esencialmente utilizar una aleación que contiene: C de 2,05 a 2,65; Cr de 6,10 a 9,80; W de 0,50 a 2,40; Mo de 2,15 a 4,70; V de 7,05 a 9,0; Nb de 0,25 a 2,45; N de 0,04 a 0,22; Si hasta 2,0; Mn hasta 2,0; Co hasta 100; S hasta 0,3; y Ni hasta 1,5; como así también elementos acompanantes hasta 2,6 e impurezas debidas a la fabricación, siendo el resto hierro (Fe), como material para la fabricación pulvimetalúrgica de piezas, que tienen un contenido en oxígeno (O) menor de 100 ppm y un contenido y una configuración de inclusiones no metálicas correspondientes a un valor KO máximo de 3, de acuerdo con el ensayo según DIN 50.602. El procedimiento para la fabricación pulvimetalúrgica de una pieza o herramienta consiste en acondicionar y pulverizar con nitrógeno, con un grado de pureza de 99,999%, la aleación líquida a polvo metálico con una distribución de tamano de grano de modo que al menos el 60% tiene un tamano de partícula <= 100 microm después de los cual se realiza el llenado del polvo en una cápsula y el cierre de la misma, manteniendo la atmósfera de nitrógeno y excluyendo una adsorción de oxígeno en la superficie de los granos, siendo el polvo elaborado en un proceso de moldeo por compresión isostática en caliente seguido de una conformación también en caliente, produciéndose debido a la temperatura el crecimiento de los monocarburos distribuidos homogéneamente hasta un tamano < de 10 microm.
