| titleOfInvention | High strength and high ductility cold rolled steel sheet with excellent press formability |
| abstract | (57) [Problem] To provide a high-strength and high-ductility cold-rolled steel sheet which is free from slab surface defects and excellent in ductility, spot weldability and press formability. SOLUTION: C: 0.05 to 0.40%, Si: 0.5 to 3.0%, Mn: 0.5 to 3.0%, P: 0.05% or less, S: 0.005% or less, Al: less than 0.10%, N: 0.0100% or less, Ti: 0.20% or less, and one or more of Ca and REM A composition containing a total of 0.0010 to 0.0500% of seeds, a ferrite content of 30% or more, a residual γ content of 3% or more in the average thickness direction, and a volume ratio of 1/16 The structure is such that the amount of residual γ in the region is 50% or less of the amount of residual γ in the central portion in the thickness direction. It is preferable to satisfy Ti / N: 2.5 or more. One or two of Nb and V, One, two or more selected from Cr, Mo, and B may be contained. |
