| description | This hot-rolled steel sheet has a prescribed chemical composition, and the metallographic structure thereof includes, by area ratio, 53.0% to 76.0% of ferrite, 3.0% to 10.0% of martensite, 14.0% to 39.0% of bainite, and 2.6% or less of pearlite. The average diameter of the martensite is 0.26 μm to 0.70 μm. Of the entire martensite interface, the total length of the interface between the martensite and the bainite is 75.0% or more relative to the total length of the entire martensite interface.
Esta lámina de acero laminada en caliente tiene una composición química predeterminada y tiene una estructura metalográfica que contiene ferrita con una relación de área de 53.0% o más y 76.0% o menos, martensita con una relación de área de 3.0% o más y 10.0% o menos, bainita con una relación de área de 14.0% o más y 39.0% o menos, y perlita con una relación de área de 2.6% o menos, y con un diámetro promedio de la martensita de 0.26 µm o más y 0.70 µm o menos, en donde, entre todas las interfaces de la martensita, la longitud total de las interfaces entre la martensita y la bainita es 75.0% o más con respecto a la longitud total de todas las interfaces de la martensita. |
