| titleOfInvention | Steel material and manufacturing method thereof |
| abstract | PROBLEM TO BE SOLVED: To provide a steel material having a ductility superior to that of a conventional TRIP steel and a manufacturing method thereof. SOLUTION: The chemical composition in mass% is C: 1.00% or less, Si: 3.00% or less, Mn: 0.2 to 7.0%, Al: 3.00% or less, Ni: 0 to 10.0%, Cu: 0 to 3.0%. , Cr: 0 to 10.0%, Ti: 0 to 1.0%, Nb: 0 to 1.0%, V: 0 to 1.0%, Mo: 0 to 2.0%, W: 0 to 1.0%, B: 0 to 0.01%, Co: 0 to 1.0%, Ca: 0 to 0.01%, Mg: 0 to 0.01%, REM: 0 to 0.01%, balance: Fe and impurities, Ceq of 0.10 to 1.00, and metal structure of volume% A tempered martensite block or ferrite crystal containing 40% or more of tempered martensite, 10% or more of bainite, 5% or more of retained austenite, 5% or more of ferrite, and occupying all the crystal grains of the retained austenite. The area ratio of the crystal grains existing inside the grains is 15% or more, and the tensile strength is 1150 MPa or more, Wood. [Selection diagram] None |
