Abstract
Acier à outils rapides à faible taux d'alliage. Un tel acier contient 0,85 % à 1 % de C, 0,40 à 1 % de Si, 1.5 à 3 % de Cr et de préférence 2,2 à 3 % de Cr, 4,0 à 6,0 % de Mo, 1,0 à 2,0 % de W, 1,0 à 2 % de V et 0,04 à 0,08 % de N, le reste étant du fer et les impuretés habituellement présentes dans les aciers à outils, telles que le Co jusqu'à 1 %, le Mn jusqu'à 0,4 % et le S et le P jusqu'à 0,03 %, tous ces pourcentage étant des pourcentages en poids, la somme des teneurs en Mo W et V étant de préférence comprise entre 7 % et 8,5 %. Application à la réalisation d'outils de coupe tels que forets hélicoïdaux, fraises en bout ou tarauds, par exemple.Low alloy high speed tool steel. Such a steel contains 0.85% to 1% C, 0.40 to 1% Si, 1.5 to 3% Cr and preferably 2.2 to 3% Cr, 4.0 to 6.0% Mo, 1.0 to 2.0% of W, 1.0 to 2% of V and 0.04 to 0.08% of N, the remainder being iron and the impurities usually present in tool steels, such as that Co up to 1%, Mn up to 0.4% and S and P up to 0.03%, all these percentages being percentages by weight, the sum of the contents in Mo W and V preferably being between 7% and 8.5%. Application to the production of cutting tools such as helical drills, end mills or taps, for example.
