Two low-carbon steels with different impurity contents were prepared by strip casting to clarify the advantages of the process. The mechanical properties and the plastic anisotropy of the as-cast, the homogenized and the recrystallization annealed strips were investigated and compared. The as-cast strips showed a good strength-ductility balance and a superior plastic anisotropy to the other strips. The largest average ferrite grain oriented in the γ-fiber is concluded to be responsible for the highest normal anisotropy in the as-cast strips. Meanwhile, the orientation volume ratio between the γ-fiber and the α-fiber showed a roughly linear relationship with the normal anisotropy of the recrystallization annealed strips. The lower planar anisotropy in the as-cast and homogenized samples was related to the orientation distribution on the ‹114› ¦¦ ND orientation line.
