| titleOfInvention | Steel sheet and method for producing steel sheet |
| abstract | A steel sheet comprising C, Si and sol.Al, further comprising Mn in mass %: more than 2.50% and less than 4.20%, the remainder being iron and impurities, and the metal at a position 1/8 of the thickness from the surface Structure by area ratio Austenite phase: 10% or more, total of tempered martensite phase and bainite phase: 5% or more, ferrite phase: 35% or more and fresh martensite phase: less than 15% %, the area ratio of the unrecrystallized ferrite phase to the ferrite phase is 10 to 50%, and the ratio of the average Mn concentration CMnγ in the austenite phase to the average Mn concentration CMnα in the ferrite phase is CMnγ /CMnα is 1.20 or more, and the deviation of Vickers hardness at a position of 1/8 of the thickness from the surface is 40 Hv or less. |
