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 3):
A steel component,\n wherein a chemical composition comprises: C: 0.35 to 0.45 mass %, Si: 0.6 to 1.0 mass %, Mn: 0.60 to 0.90 mass %, P: 0.010 to 0.035 mass %, S: 0.06 to 0.10 mass %, Cr: 0.25 mass % or less, V: 0.20 to 0.40 mass %, Zr: 0.0002 to 0.0050 mass %, N: 0.0060 to 0.0150 mass %, Bi: 0.0001 to 0.0050 mass %, Ti: 0 to 0.050 mass %, Nb: 0 to 0.030 mass %, Mg: 0 to 0.0050 mass %, REM: 0 to 0.0010 mass %, and a remainder including iron and impurities, 90 area % or more of a metallographic structure is configured with a ferrite and a pearlite, and an average number density of Mn sulfides having an equivalent circle diameter of 1 to 5 \u03bcm, extending along a rolling direction, 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 .
