Influence of hot rolled microstructure on the recrystallization behavior at surface layer of cold rolled low carbon steel sheets was studied by optical microscopic and X-ray reflection techniques. The main results obtained are as follows. 1) Recrystallization at surface layer delays in comparison with interior region, and it depends mainly on {001}<110> developed at the surface layer by cold rolling. 2) Delay of recrystallization is more remarkable at coarser grains in hot rolled steel sheets. It is considered that the delay is attributed to the effect grain size on the recrystallization and the promotion of formation of {100} in coarse grains. 3) The surface texture of cold rolled sheet forms in very thin layer, about 2.5% from surface in thickness, and the formation of {100} is faster than that of {111}.
