Abstract

Una lámina de acero tiene una composición química específica y tiene una estructura de acero que comprende, en % de área, 20 a 95% de primera martensita en la cual al menos dos granos de carburo de hierro que tienen un diámetro de círculo equivalente de 2 a 500 nm se contienen en cada listón, 15% o menos de ferrita, 15% o menos de austenita retenida y el resto compuesto de bainita y/o segunda martensita en la cual menos de dos granos de carburo de hierro que tienen un diámetro de círculo equivalente de 2 a 500 nm se contienen en cada listón. La fracción de área total de los granos de dirección ND//<111> y los granos de dirección ND//<100> en la lámina de acero es de 40% o menos. El contenido de la solución sólida C en la lámina de acero es de 0.44 ppm o más.
