Thick steel plate |
| abstract |
Wherein the metal structure in the surface layer contains at least 80% by area or more of the ferrite and the upper bainite in a fraction, and the effective crystal grain size of at least one of the ferrite and the upper bainite is Wherein the mean circle equivalent diameter of the crystal grains of the remaining structure excluding the ferrite and the upper bainite in the surface layer is 3.0 占 퐉 or less and the value of the dislocation density? 10 15 m -1 or less. Thereby, a steel sheet having excellent fatigue characteristics is provided. |
