Abstract

Se proporciona una lámina de acero galvanizado por inmersión en caliente y una lámina de acero recocida galvanizada en caliente que tiene al menos 980 MPa, que tiene excelente capacidad de chapado; formabilidad en términos de flexibilidad, capacidad de expansión de huecos, y resistencia retardada a la fractura y también que tiene excelentes propiedades de absorción de impacto. La lámina de acero chapada de alta resistencia de la presente invención tiene una capa chapada sobre la superficie de una lámina de acero base y contiene componentes de acero predeterminados. La lámina de acero incluye, en orden desde la interfaz de la lámina de acero base y la capa chapada hacia la lámina de acero base: una capa blanda que tiene una dureza Vickers que es 90% o menos de la dureza Vickers en una porción t/4 de la lámina de acero base, donde t es un espesor de lámina de la lámina de acero base; y una capa dura que consiste de una estructura que está compuesta principalmente de martensita y bainita, y en la que el tamaño de grano promedio de la austenita previa es 20 µm o menos. La profundidad promedio D de la capa blanda es de 20 µm o mayor, y la profundidad promedio d de una capa interna de óxido es de 4 µm o mayor y menor que D.
