The effect of Al contents ranging from 0.002% to 0.025% on secondary recrystallization behavior of ultra-low carbon 2.2%Si-1.5%Mn steels was investigated. The secondary recrystallization at relatively low annealing temperature of 1148K was achieved only in the steel with 0.007% sol.Al. The development of Goss texture was affected by annealing atmosphere, and the Goss texture as same as that of conventional grain oriented electrical steels was obtained by annealing in N2 containing atmosphere. The Goss texture of 0.007% sol. Al steel would be developed due to the optimum inhibitor effect of fine (Al, Si, Mn) nitrides whose crystal structure was similar to AlN.
