Abstract

L'invention concerne des aciers alliés de grande résistance et de haute ténacité. Les aciers ont les compositions suivantes : 0,50 - 1,00 % C, 0,10 - 1,50 % I, O,50 - 1,50 % Mn, max. 0,045 % P, max. 0,045 % S, 0,20 - 0,90 % Mo et/ou 0,20 -2,00 % Cr, le complément de fer et les impuretés habituelles, et ils ont été soumis à une trempe bainitique dans la zone du point de transformation martensite et jusqu'à un degré de transformation au maximum d'environ 85 %. Application aux pièces mécaniques de haute qualité.
