Abstract

Después de que el laminado de acabado a baja temperatura se haya realizado como laminado en caliente en un material de acero que tenga una composición química que contenga, % en masa, C: 0.07% a 0.20%, Si: 1.50% o menos, Mn: 1.0% a 4.0%, P: 0.030% o menos, S: 0.0030% o menos, Al: 0.010% a 1.000%, el enfriamiento se lleva a cabo a una velocidad promedio de enfriamiento de 10°C/s o superior hasta una temperatura de 500°C, el enfriamiento rápido se lleva a cabo además en un intervalo de temperaturas que va desde una temperatura Ms hasta una temperatura de (temperatura Ms - 200°C), el enrollado se lleva a cabo después en un intervalo de temperaturas bajas de 250°C o inferior, y la lámina de acero enrollada se desenrolla y se somete además a laminado con una cantidad determinada o más de carga de laminado por unidad de anchura y similares. En consecuencia, es posible obtener una lámina de acero laminada en caliente de alta resistencia excelente en términos de resistencia a la fractura retardada que tiene una microestructura que incluye, en términos de fracción de área, un 95% o más de una fase de martensita en una posición situada a 1/4 del grosor de la lámina de acero, en la que una relación de aspecto promedio de los granos de austenita anteriores es de 3.0 o más, una cantidad de relajación del esfuerzo después de un lapso de 5 minutos de 20 MPa o menos en una prueba de relajación de esfuerzo con una tracción aplicada de 400 MPa, y una resistencia a la tracción de 1180 MPa o superior.
