Abstract
La presente se refiere a una chapa de acero recocido y laminada en frío, con una resistencia superior a 1200 MPa, cuya composicion comprende, con contenidos expresados en peso: 0,10% <= C <= 0,25%; 1% <= Mn <= 3%, Al >= 0,010%; Si <= 2,990%; S <=0,015%: P<= 0,1%; N <= 0,008%, entendiéndose que 1 % <= Si + Al <= 3%, donde la composicion comprende, opcionalmente: 0,05% <= V <= 0,15%; B <= 0,005%; Mo <= 0,25%; Cr <= 1,65%; entendiéndose que Cr + 3Mo >= 0,3%, Ti en una cantidad tal que Ti/N >=4 y Ti <= 0,040%, donde el resto de la composicion consiste en hierro y en las impurezas inevitables que derivan de la fusion; la microestructura de dicho acero comprende del 15 al 90% de bainita y el resto consiste en martensita y austenitaresidual. Reivindicacion 14: Un proceso para fabricar una chapa de acero laminada en frío, con una resistencia superior a 1200 MPa y un alargamiento al romperse superior al 10%, en el cual: se provee un acero, que tiene una composicion de acuerdocon la reivindicacion 2; luego se cuela un producto semiterminado a partir de este acero; luego dicho producto semiterminado se lleva a una temperatura superior a 1150°C; luego dicho producto semiterminado se lamina en caliente, a fin de obtener unachapa laminada en caliente; luego dicha chapa se enrolla; luego dicha chapa laminada en caliente se decapa; luego dicha chapa se lamina en frío con un índice de reduccion de entre 30 y 80%, a fin de obtener una chapa laminada en frío; y luego lacitada chapa laminada en frío se recalienta a un índice Vc, de entre 5 y 15°C/s, hasta una temperatura T1, de entre Ac3 y Ac3 + 20°C, y se mantiene allí por un tiempo t1de entre 50 y 150 s; después, la citada chapa se enfría a una velocidad VR1superior a 40°C/s pero inferior a 100°C/s hasta bajar a una temperatura T2 de entre (Ms-30°C y Ms + 30°C) , manteniéndose la chapa a dicha temperatura T2 durante un tiempo t2 entre 150 y 350 s y luego se enfría a un índice VR2 de menos de 30°C/shasta la temperatura ambiente.
