Abstract
Se provee una lámina de acero que tiene una composición química predeterminada, en donde los precipitados que tienen un diámetro de menos de 0.1 µm están presentes en una densidad numérica de 10 a 200/µm2 en una región de profundidad de 1 a 10 µm desde la superficie, la cantidad de C disuelto en una región de profundidad de 10 a 60 µm desde la superficie es inferior a 0.20% en masa, y la resistencia a la tracción es de 1200 MPa o más. Además, se provee un método para producir una lámina de acero que comprende un paso de laminar en caliente una placa de acero que tiene una composición química predeterminada, luego enrollarla a 580°C o menos, un paso de decapar la lámina de acero laminada en caliente para eliminar las incrustaciones de óxido y eliminar la capa superficial de la lámina de acero laminada en caliente hasta al menos 5 µm, y un paso de laminar en frío la lámina de acero laminada en caliente, luego mantenerla en una atmósfera con un punto de rocío de -20 a 20°C en una región de temperatura de 200 a 400°C durante 20 a 180 segundos y mantenerla en una región de temperatura de 740 a 900°C durante 40 a 300 segundos.
