Abstract

La presente invención proporciona una lámina de acero laminada en caliente de alta resistencia que contiene bainita, que tiene excelente capacidad de ser moldeada o trabajabilidad isotrópica. Esta lámina de acero laminada en caliente de alta resistencia que contiene bainita contiene, en términos de % en masa, 0.07-0.2%, excluyendo 0.07% de C, 0.001-2.5% de Si, 0.01-4% de Mn, hasta 0.15% de P (excluyendo 0%), hasta 0.03% de S (excluyendo 0%), hasta 0.01% de N (excluyendo 0%), y 0.001-2% de Al, con el resto comprendiendo Fe e impurezas incidentales. En la parte central de la dirección de espesor que se extiende desde 5/8 hasta 3/8 del espesor de la lámina en términos de profundidad desde una superficie de la lámina de acero, el promedio de los valores de la densidad de polo de las orientaciones {100}<011> a {223}<110> es 4.0 o menos y la densidad de polo de la orientación de cristal {332}<113> es 4.8 o menos. La lámina de acero tiene un diámetro de grano de cristal promedio de 10 µm o menos y una temperatura de transición de aparición de la fractura Charpy (vTrs) de -20°C o menos. La lámina de acero tiene una microestructura que comprende 35% o menos de ferrita pro-eutectoide y una fase generada por la transformación de baja temperatura como el resto.
