Abstract:
There is a hot-rolled steel according to one aspect of the invention including predetermined chemical compositions including 0.0001 to 0.0050 mass % of Bi, in which 90 area % or more of a metallographic structure is configured with a ferrite and a pearlite, and an average number density of Mn sulfides extending along a rolling direction and having an aspect ratio exceeding 10 and equal to or smaller than 30, which is measured on a cross section parallel to the rolling direction, is 50 to 200 number/mm 2 .

Claim (Index 4):
The steel component according to  claim 3 ,\n wherein, in a case where tensile fracture of the steel component is performed by tensile stress parallel to the rolling direction to form fracture surfaces, steps, in which a difference in height towards a direction parallel to the tensile stress is equal to or greater than 80 \u03bcm and an angle with respect to the direction parallel to the tensile stress is equal to or smaller than 45 degrees, and which are observed on the cross section parallel to the rolling direction, are formed on the fracture surface at an average number density of equal to or greater than 2.0 pieces per 10 mm, a brittle fracture surface is 98 area % or more with respect to the fracture surface, and an average number density of cracks or recesses, in which an angle with respect to the direction parallel to the tensile stress exceeds 45 degrees, which are formed over a length equal to or longer than 80 \u03bcm and observed on the cross section parallel to the rolling direction, and in which a part of the cracks or the recesses are propagated to an inner portion of the steel component, is smaller than 3.0 pieces per 10 mm on the fracture surface.
