PURPOSE:To manufacture the titled steel sheet by rolling a steel contg. a sufficient amount of soluble (C+N) to cause violent dynamic strain aging and carrying out recrystallization annealing. CONSTITUTION:A steel contg.=10ppm soluble (C+N) is rolled at 200-500 deg.C and =20% draft to cause violent dynamic strain aging by dislocation moved during working and the interaction between C and N in the steel. Recrystallization annealing is then carried out to manufacture a steel sheet having a texture with developed (110)(001) orientation component. When the steel sheet is press-formed, the resulting parts have remarkably enhanced tensile rigidity.
