Abstract

L'invention concerne des outils de travail à chaud des métaux sous fortes contraintes et soumis à des chocs thermiques importants. Ces outils sont réalisés en alliage contenant de 90 à 97 % de tungstène du fer et/ou du nickel en quantité totale comprise entre 2 et 10 %, et éventuellement d'autres éléments d'alliage tels que Cr, Mo, Co en quantité totale inférieure à 8 %. Application aux filières et aux mandrins de perçage de tubes sans soudure.The invention relates to tools for hot working metals under high stress and subjected to high thermal shocks. These tools are made of an alloy containing 90 to 97% of tungsten, iron and / or nickel in a total amount of between 2 and 10%, and possibly other alloying elements such as Cr, Mo, Co in total amount. less than 8%. Application to dies and mandrels for drilling seamless tubes.
