Abstract
Se describe una lámina de acero galvanizada por inmersión en caliente de alta resistencia que tiene una tensión de rotura de 1,180 MPa o más y excelente en propiedad de anti-choque y capacidad de flexión. También se describe un método para la producción de la lámina de acero galvanizada por inmersión en caliente de alta resistencia. La lámina de acero galvanizada por inmersión en caliente de alta resistencia tiene un recubrimiento galvanizado por inmersión en caliente sobre su superficie y contiene C: más de 0.10% y menos de 0.18%, Si: 0.01 a 1.00%, Mn: 1.5 a 4.0%, P: 0.100% o menos, S: 0.020% o menos, Al: 0.010 a 0.500%, Cr: 0.010 a 2.000%, Nb: 0.005 a 0.100%, Ti: 0.005 a 0.100%, y B: más de 0.0005% y 0.0030% o menos, con el resto siendo Fe e impurezas inevitables. La lámina de acero incluye ferrita con una fracción de área de 0 a 10%, martensita con una fracción de área de 15 a 60%, martensita revenida con una fracción de área de 20 a 50%, y ferrita bainítica con una fracción de área de 20 a 50%. El tamaño de grano promedio de cada una de martensita masiva, la martensita revenida, y la ferrita bainítica es de 15 µm o menos. Un valor obtenido restando la fracción de área de la martensita revenida de la fracción de área de la ferrita bainítica es de 20% o menos, y la fracción de área de regiones de fase de martensita que son contiguas solamente a regiones de fase de martensita con respecto a la fracción de área total de regiones de fase de martensita es de 5% o menos. Un valor obtenido restando la dureza Vickers a una profundidad de 20 µm desde una superficie de la lámina de acero de la dureza Vickers a una profundidad de 100 µm desde la superficie de la lámina de acero es de 30 o más.
