| titleOfInvention | Cold rolled steel sheet and hot-dip galvanized cold-rolled steel sheet |
| abstract | The cold-rolled steel sheet according to the present invention is a cold-rolled steel sheet having a tensile strength of 980 MPa or more, which has a predetermined chemical composition, a metallographic microstructure in terms of area%, a ferrite iron: 1 to 29%, and a residual Worthite iron: 5 ~20%, Ma Tian loose iron: less than 10%, Bora iron: less than 5%, the rest: toughened iron or tempered Ma Tian loose iron, toughened iron and tempered Ma Tian loose iron, fat iron and equivalent The sum of the interface lengths of the contact between the mashed loose iron or the residual Worth iron having a radius of 1 μm or more is 100 μm or less per 1000 μm 2 . Such a cold-rolled steel sheet has excellent workability and low-temperature toughness, and is particularly excellent in low-temperature toughness after introduction of plastic strain. |
