Abstract

A hot-rolled steel sheet has a specified chemical composition, and has a structure containing, in area%, ferrite and bainite at the total content of 75 to 95% and martensite at a content of 5 to 20%, wherein, when a boundary having a degree of misorientation of 15° or more is defined as a grain boundary and an area surrounded by the grain boundary and having an equivalent circle diameter of 0.3 µm or more is defined as a crystal grain, the areal ratio of crystal grains each having a degree of intergranular misorientation of 5 to 14° is 10 to 60% in the structure.
