In this paper, the microstructural of the E235 hot rolled steel tube after normalizing and cold drawing were characterized by optical microscopy, EBSD (Electron BackScatter Diffraction) analysis performed on scanning electron microscope. The input feedstock with dimensions of circle divide 31.8 mm x 2.6 mm (O.D x W.T.) was cold drawn in one drawing passes with fixed plug to the final dimensions of circle divide 25.0 mm x 1.5 mm. The development of grain texture in 3 different regions was analyzed on a longitudinal section of the tube. The stress state in the tube material during drawing was calculated by finite element software and the development of the texture depending on the stress state in three different directions using cylindrical coordinates with respect to the drawing direction was evaluated.
