Abstract

Se proporciona una chapa de acero con una tensión de rotura (TS) de 1180 MPa o más, alta resistencia a la LME, y buenas propiedades de fatiga de la soldadura, un miembro y un método para producirlos. Una chapa de acero de acuerdo con la presente invención tiene una composición química específica y una microestructura de acero específica, donde los granos de cristal que contienen un óxido de Si y/o Mn en una región dentro de 4.9 µm en una dirección del espesor desde una superficie de la chapa de acero que tiene un tamaño de grano promedio en el intervalo de 3 a 10 µm, la concentración más baja de Si LSi y la concentración más baja de Mn LMn en la región dentro de 4.9 µm en la dirección del espesor desde la superficie de la chapa de acero y una concentración de Si TSi y una concentración de Mn TMn en una posición de un cuarto del espesor de la chapa de acero satisface la siguiente fórmula (1), y la chapa de acero tiene una tensión de rotura (TS) de 1180 MPa o más. LSi + LMn = (TSi + TMn)/5 (1).
