Note : 1. "L" and "C" means the specimens cut parallel and traverse to the rolling direction, respectively.
2. Tension tests were made on No.13A specimens according to JIS Z 2201 (1998).
3. Bend and lamination factor tests were made according to the method JIS C 2550 (2000).
4. The specimens were tested as sheared.
5. Test values shown above are the typical ones, not for guarantee.
6. The specimens with A coating were used for lamination factor tests.
