Abstract

Se provee una lámina de acero laminada en caliente que comprende una composición predeterminada en la que la lámina de acero laminada en caliente comprende una estructura dual de, por fracción de área, una fracción estructural de una fase de martensita de 10 a 40% y una fracción estructural de una fase de ferrita de 60% o más, tiene un tamaño de grano promedio de granos de ferrita de 5.0 µm o menos, y tiene una tasa de cobertura de granos de martensita por granos de ferrita de más de 60%. También se provee un método para producir una lámina de acero laminada en caliente que comprende laminar una lámina de acero en donde las cargas de laminación respectivas de los tres soportes de laminación finales son 80% o más de un soporte de laminación inmediatamente anterior y un valor promedio de estas temperaturas de laminación es de 800 a 950°C, y enfriar forzadamente, luego enrollar la lámina de acero en donde el enfriamiento forzado incluye enfriamiento iniciado dentro de 1.5 segundos después de que finaliza la laminación y enfriar la lámina de acero mediante una velocidad de enfriamiento promedio de 30°C/segundo o más hasta 600 a 750°C, enfriamiento natural durante 3 segundos o más y 10 segundos o menos, y enfriamiento a una velocidad de enfriamiento promedio de 30°C/segundo o más hasta 200°C o menos.
