Abstract

Esta lámina de acero para nitruración suave con gas tiene una composición química y una estructura metalográfica predeterminadas, en las que, cuando el espesor de la lámina se indica como t, el ancho de la lámina, que es un ancho en una dirección perpendicular a la dirección de laminado, se indica como w, y los tamaños de grano efectivos se miden en siete posiciones de w/8, w/4, 3w/8, w/2, 5w/8, 3w/4 y 7w/8 en la dirección del ancho desde una porción extrema en la dirección del ancho en una posición de profundidad de t/4 desde una superficie, un tamaño de grano efectivo promedio, que es un promedio de los tamaños de grano efectivos en las siete posiciones, es de 8.0 a 35.0 µm, y una diferencia de tamaño de grano efectivo, que es una diferencia entre un valor máximo y un valor mínimo entre los tamaños de grano efectivos en las siete posiciones, es de 10.0 µm o menos.
