Abstract

PERFECCIONAMIENTOS EN LA OBTENCION DE ACEROS APLICADOS A LA FABRICACION DE HERRAMIENTAS AGRICOLAS. SE INCLUYE EL NIBONIO (NB) EN PROPORCION CORRESPONDIENTE PARA ELIMINACION DE GRANULACION GRANDE, AMPLIA LA BANDA DE TEMPERATURAS PARA LA AUSTENIZACION USUAL (COMPOSICION 70DA9 DE LA NORMA ABNT), MEJORANDO LA RESISTENCIA AL DESGASTE POR ABRASION, Y EVITANDO LA FRAGILIDAD DEL REVENIDO. EL GRANO FINO TIENE COMO RESULTADO UN AUMENTO DE LA TENACIDAD AL IMPACTO, LIMITE DE RESISTENCIA Y MEJORA DE LA RESISTENCIA DE LOS DISCOS DE ARADOS Y GRADAS.
