HIGH STRENGTH STEEL SHEET HAVING EXCELLENT PHOSPHATE TREATABILITY |
| 摘要 |
PROBLEM TO BE SOLVED: To provide an Si-added high strength steel sheet having excellent phosphate treatability by controlling Si based oxides produced on the surface of the Si-added steel sheet having phosphate treatability remarkably inferior to that of soft steel. SOLUTION: The content of Si based oxides in the surface of a high strength steel sheet is controlled to≤20 mg/m<SP>2</SP>expressed in terms of SiO<SB>2</SB>. COPYRIGHT: (C)2007,JPO&INPIT
