Abstract

Una hoja de acero laminada en caliente que tiene un grosor de 3-20 mm y contiene cantidades específicas de C, Si, Mn, P, S, A1 y N, estando constituido el resto por hierro e impurezas inevitables. Esta hoja de acero laminada en caliente contiene una cantidad específica de N disuelto en sólidos y el contenido en C y N satisface la relación 10C + N = 3,0. Esta hoja de acero laminada en caliente contiene ferrita bainítica y perlita, respectivamente en una razón de área del 5% o más y en una razón de área de menos del 20% en relación con la estructura completa, estando constituido el resto por ferrita poligonal. El tamaño de grano cristalino promedio de la ferrita bainítica es de 3-50 µm.
