STEEL SHEET AND MANUFACTURING METHOD THEREFOR |
| 摘要 |
Disclosed are a steel sheet having excellent and a method for producing the same. The disclosed steel sheet comprises, by weight, 0.005-0.06% carbon (C), 0.2% or less silicon (Si), 1.0-2.0% manganese (Mn), 0.01% or less sulfur (S), 0.2-2.0% aluminum (Al), one or more of chromium (Cr) and molybdenum (Mo) in an amount satisfying 0.3≦[Cr wt %]+0.3[Mo wt %]≦2.0, and 0.008% or less nitrogen (N), with the remainder being iron (Fe) and inevitable impurities, wherein the density of dislocations in the ferrite matrix of the steel sheet is 1×1013/m2 or more. |
