| titleOfInvention | High-strength hot-rolled steel sheet and manufacturing method thereof, and high-strength electric resistance welded steel pipe and manufacturing method thereof |
| abstract | A high-strength hot-rolled steel sheet and its manufacturing method, and a high-strength electric resistance welded steel pipe and its manufacturing method are provided. In the high-strength hot-rolled steel sheet of the present invention, the steel structure at the center of the sheet thickness contains bainite and ferrite at a specific volume fraction, has an average grain size of 9.0 μm or less, and has a dislocation density of 1.0×10 14 . m −2 or more and 1.0×10 15 m −2 or less, the steel structure at a depth of 0.1 mm from the plate surface contains bainite and ferrite in specific volume fractions, and has an average grain size of 9.0 mm. 0 μm or less, a dislocation density of 5.0×10 14 m −2 or more and 1.0×10 15 m −2 or less, and a maximum low-angle grain boundary density of 1.4×10 6 m −1 or less. , the plate thickness is 15 mm or more. |
