This paper presents the effect of microstructure and crystallographic texture by developed in hot rolling and different post-treatments on anisotropic and mechanical properties of SAE 970X steel. The experimental results showed that the hot-rolled sample followed by quenching and consequent tempering at 700 C led to a significant improvement in anisotropic and mechanical properties. This happened due to the reduction in the number of grains oriented with {001} planes parallel to normal direction. Also, the formation of new strain-free and recrystallized grains associated with {111}//ND and {110}//ND directions improved the mechanical properties. These grains corresponded to the close-packed planes in BCC structure as well.
