HOT-ROLLED STEEL SHEET, COLD-ROLLED STEEL SHEET, GALVANIZED STEEL SHEET, AND PROCESSES FOR PRODUCING THESE |
摘要 |
Disclosed is a hot-rolled steel sheet in which at least the sheet-thickness central part which ranges from 5/8 to 3/8 the sheet thickness in terms of distance from the steel sheet surface has an average X-ray random intensity ratio for the {100}<011> to {223}<110> orientations of 1.0-6.0 and has an X-ray random intensity ratio for the {332}<113> crystal orientation of 1.0-5.0. The steel sheet further has an rC, which is the value of r in a direction perpendicular to the rolling direction, of 0.70-1.10 and an r30, which is the value of r in a direction having an angle of 30º with respect to the rolling direction, of 0.70-1.10. |
