Abstract

L'invention porte sur un procédé pour la production d'un acier laminé à chaud à partir d'un acier, dont la composition, sous forme de pourcentages en poids, est de 0,075 - 0,12 % de C, 0,1 - 0,8 % de Si, 0,8 - 1,7 % de Mn, 0,015 - 0,08 % d'Al, moins de 0,012 % de P, moins de 0,005 % de S, 0,2 - 1,3 % de Cr, 0,15 - 0,80 % de Mo, 0,01 - 0,05 % de Ti, 0,0005 - 0,003 % de B, 0,02 - 0,10 % de V, moins de 0,3 % de Nb, moins de 1 % de Ni, moins de 0,5 % de Cu, le reste étant du fer et des impuretés inévitables. L'invention porte en particulier sur des aciers en forme de tôle martensitiques ayant subi une trempe directe, sur lesquels un recuit de revenu est effectué, c'est-à-dire des aciers de revenu et sur leur production. L'acier laminé à chaud selon l'invention est exceptionnellement résistant au revenu après le procédé de trempe directe, le revenu permettant de lui conférer une résistance encore plus élevée (Rp 0,2 ≥ 890 MPa) combinée en même temps avec une bonne résistance au choc (V Charpy (-20°C) ≥ 37 J/cm2) et une bonne aptitude au bordage ainsi qu'une bonne aptitude au soudage.
