Inventor: INAZUMI TORU
IPC: C22C38/00
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To obtain a steel plate excellent in shape as well as in plating adhesion after bending by preparing a steel plate for long-size member, in which Lankford value in a direction orthogonal to a bending axis is specified. SOLUTION: A steel plate for long-size member, in which Lankford value (r-value) in a direction orthogonal to a bending axis is regulated to <=1.0, is prepared. By regulating r-value to <=1.0, elongation and contraction, in a direction of a bending axis, occuring in the interior side and exterior side of the end bending part, are reduced and the occurrence of warpage is inhibited. Further, the relationship between the r-value and the yield point YP (kgf/mm<2> ) in a direction orthogonal to the bending axis is regulated so that it satisfies inequality r×(YP)<1/2> <=6.0. By reduction of YP, warpage mainly in the central part can be reduced and also warpage in the end can be reduced, though slightly.  By this method, the steel plate, in which deterioration in shape as well as in plating adhesion after working is prevented and improvement of reliability and reduction of inferior working are attained, can be obtained.
