CA 2659849

The present invention relates to a tool steel, in particular a hot-work steel, having the following composition: 0.26 to 0.55% by weight C; < 2% by weight Cr; 0 to 10% by weight Mo; 0 to 15% by weight W; wherein the W and Mo contents in total amount to 1.8 to 15% by weight; carbide-forming elements Ti, Zr, Hf, Nb, Ta forming a content of from 0 to 3% by weight individually or in total; 0 to 4% by weight V; 0 to 6% by weight Co; 0 to 1.6% by weight Si; 0 to 2% by weight Mn; 0 to 2.99% by weight Ni; 0 to 1% by weight S; remainder: iron and inevitable impurities. The hot-work steel has a significantly higher thermal conductivity than known tool steels.

La présente invention concerne un acier à outils, notamment un acier pour travail à chaud, de composition suivante : 0,26 à 0,55 % en poids de C ; < 2 % en poids de Cr ; 0 à 10 % en poids de Mo ; 0 à 15 % en poids de W ; la somme des teneurs en W et Mo étant comprise entre 1,8 et 15 % en poids ; éléments formant des carbures Ti, Zr, Hf, Nb, Ta en une teneur de 0 à 3 % en poids seuls ou en combinaison ; 0 à 4 % en poids de V ; 0 à 6 % en poids de Co ; 0 à 1,6 % en poids de Si ; 0 à 2 % en poids de Mn ; 0 à 2,99 % en poids de Ni ; 0 à 1 % en poids de S ; le reste étant du fer et d'inévitables impuretés. L'acier pour travail à chaud présente une conductivité thermique considérablement plus élevée que les aciers à outils connus.
