  In this research formability behavior and texture of St۱۴ low carbon steels produced by Foolad Mobarakeh plant for deep drawing application had been studied. Plate textures were characterized by X-ray Diffraction technique. To evaluate formability behavior one dimensional tensile test was carried out and related parameters were recognized. Moreover Eriksson experiment and spherical pattern printing on samples were also implemented to scheme ultimate formability curve (FLD). Ultimate formability curve area was calculated using plane strain variations (FLD۰). Effect of mechanical parameters on ultimate formability curve consist of yield strength, tensile strength, strain hardening coefficient, perpendicular anisotropy and texture were also studied. The results show that by increasing yield strength and tensile strength, lower area of ultimate formability curve decreases. In contrast by increasing total elongation, strain hardening coefficient and perpendicular anisotropy parameter, plate formability has been enhanced
