Abstract
La presente invención, en consideración de los problemas de la técnica anterior, proporciona una carrocería de estampado en caliente que logra simultáneamente la alta capacidad de flexión y alta ductilidad para obtener resistencia al impacto y también resistencia a la fragilidad por hidrógeno y se mantiene baja la dispersión en la dureza. La carrocería de estampado en caliente según la presente invención está provista de una parte media en el espesor o grosor de la lámina y una capa suavizada o blanda dispuesta a ambos lados o en un lado de la parte media en el grosor de la lámina. La parte media en el espesor de la lámina tiene una dureza de 500Hv a 800Hv y tiene estructuras metálicas desde una profundidad de 20 µm por debajo de la superficie de la capa suavizada hasta una profundidad de 1/2 del grosor de la capa suavizada con una tasa de área de un total de granos de cristal con una diferencia máxima de orientación de cristal dentro de los granos de cristal de 1° o menos y granos de cristal con una diferencia de orientación máxima de cristal dentro de los granos de cristal de 8° o más y 15° o menos de 50% o más y menos superior al 85%, cuando una región rodeada por límites de grano que tiene una diferencia de orientación de 15° o más en una sección transversal paralela a la dirección del grosor de la lámina se define como un "grano de cristal".
