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.The invention relates to high strength and high toughness alloy steels. The steels have the following compositions: 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 and / or 0.20 -2.00% Cr, the complement of iron and the usual impurities, and they were subjected to bainitic quenching in the zone of the point of martensite transformation and up to a maximum transformation degree of about 85%. Application to high quality mechanical parts.
