Abstract

La invención pone a disposición un producto plano de acero, que tiene una resistencia a la tracción Rm = 950 MPa, un límite elástico = 800 MPa y un alargamiento de rotura A50 = 8 %. El producto plano de acero está formado un acero que está constituido por (en % en peso) del 0,05 - 0,20 % de C, del 0,2 - 1,5 % de Si, del 0,01 - 1,5 % de Al, del 1,0 - 3,0 % de Mn, = 0,02 % de P, = 0,005 % de S, = 0,008 % de N, así como en cada caso opcionalmente del 0,05 - 1,0 %, del 0,05 - 0,2 % de Mo, del 0,005 - 0,2 % de Ti, del 0,001 - 0,05 % de Nb, del 0,0001 - 0,005 % de B, el resto Fe e impurezas inevitables. Se aplica aquí que 1,5 = ? = 3, con ?=(%C+%Mn/5+%Cr/6)/(%Al+%Si) y %C, %Mn, %Cr, %Al, %Si respectivo contenido de C, Mn, Cr, Al o Si del acero. Al mismo tiempo presenta el producto plano de acero una estructura que está constituida por (en % en superficie) = 5 % de bainita, = 5 % de ferrita poligonal, = 90 % de martensita así como = 2 % en volumen de austenita residual, siendo al menos la mitad de la martensita martensita recocida. La invención menciona también un procedimiento para la fabricación de un producto plano de acero de este tipo.
