Effects of the coiling temperature on the microstructures and mechanical properties of 08Al hot-rolled steel sheet were investigated. Meanwhile, cold rolling and annealing experimental verifications were performed in the laboratory. The results show that when coiling is carried out at 592°C, the hot-rolled steel sheet exhibits good comprehensive mechanical properties. After cold rolling and annealing treatments, the experimental steel sheet also shows the optimal deep-drawability. The volume fraction of {111}⟨UVW⟩ texture component is the highest and the values of {111}⟨UVW⟩/{001}⟨110⟩ and {111}⟨UVW⟩/{001}⟨100⟩ are both the largest. However, the strip-like or massive cementites appear in the steel sheet as the coiling temperature is higher than 620°C, which is harmful to the deep-drawability of the experimental steel. Therefore, the coiling temperature should be controlled to be lower than 620°C in the 08Al deep drawing steel sheet.
