Abstract
Los objetivos de la presente invención son proporcionar una lámina de acero de alta resistencia que tiene una tensión de rotura de 980 MPa o mayor y que tiene una excelente resistencia a la fractura retardada y proporcionar un método para la producción de la misma. Una lámina de acero de alta resistencia de la presente invención tiene una composición química específica. Además, en la lámina de acero, un grado de segregación de Mn en una región específica es de 1.5 o menos; una concentración máxima de P en una región específica es de 0.08% en masa o menos; en una región dentro de 100 µm de una superficie en una dirección de espesor de lámina, por lo menos un grupo específico de partículas de MnS está presente, el número de grupos específicos de partículas de MnS es de 2.0 o menos por 1 mm2, y el número de inclusiones específicas a base de óxido es de 8 o menos por 1 mm2, según lo visto en una sección transversal en la dirección de espesor de lámina y paralela a una dirección de laminación de la lámina de acero; de todas las inclusiones a base de óxido, inclusiones a base de óxido que tienen una composición específica están presentes en una relación numérica de 80% o más; la microestructura incluye, en términos de una fracción de volumen, 30 a 95% de martensita, 5 a 70% de fase de ferrita, menos de 30% (y 0% o mayor) de bainita, y menos de 2.0% (y 0% o mayor) de fase de austenita; y una tensión de rotura es de 980 MPa o mayor.
