| titleOfInvention | steel sheet |
| abstract | It has a tensile strength of 1320 MPa or more and a product of tensile strength of 26000 MPa% or more and total elongation, which is useful for structural members, particularly automobile skeletal members, reinforcing members, and collision-resistant members, and has a small variation in elongation characteristics. A steel sheet having a high Mn content is provided. In mass%, C: more than 0.18% and less than 0.45%, Si: 0.001% or more and less than 3.50%, Mn: more than 4.00% and less than 9.00%, and sol. Al: 0.001% or more and less than 1.00%, B: 0.0003% or more and 0.010% or less, P: 0.023% or less, S: 0.010% or less, N: less than 0.050%, O: less than 0.020%, and optionally containing elements, the balance is iron and impurities, the tensile strength is 1320 MPa or more, the product of tensile strength and total elongation is 26000 MPa% or more, the total elongation A steel sheet having a standard deviation of 2.5 or less. |
