The ecrystallization behaviors during continuous annealing process were studied in extra low carbon Al-killed steels with varying Mn content. The less the Mn content, the higher the nucleation rate of {111} grains. The {111} recrystallization it difficult when Mn content is excessively high. There exists, an optimum range of Mn content, annealing temperature and annealing time. Cold rolled texture is {111} $lt;hkl$gt; fibre texture and recrystallization texture is mainly of {111} $lt;112$gt; component. A model for nucleation and grain growth is proposed to explain the recrystallization process from {111} $lt;hkl$gt; cold rolled texture to {111} $lt;112$gt; recrystallized texture with movement of coincidence boundary.
