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.
