High-strength steel sheet having excellent bendability and formability and method for manufacturing same

A high-strength steel sheet having excellent bendability and formability, the steel sheet comprising:

• by weight, 0.05 to 0.12% of carbon (C), 2.0 to 3.0% of manganese (Mn), 0.5% or less excluding 0% of silicon (Si), 1.0% or less excluding 0% of chromium (Cr), 0.1% or less excluding 0% of niobium (Nb), 0.1% or less excluding 0% of titanium (Ti), 0.0025% or less excluding 0% of boron (B), 0.02 to 0.05% of aluminum (sol.Al), 0.05% or less excluding 0% of phosphorus (P), 0.01% or less excluding 0% of sulfur(S), 0.01% or less excluding 0% of nitrogen (N), with a balance of Fe and inevitable impurities;
• and
• a microstructure comprising, by area fraction, 35 to 50% of ferrite, 35 to 45% of bainite, and a balance of martensite,
• wherein the ferrite includes a non-recrystallized ferrite, by area fraction, in a range of 8 to 15% of a total amount of the microstructure, and a recrystallized ferrite, by area fraction, in a range of 27 to 35% of the total amount of the microstructure.
