Two kinds of drawing processes, the unidirectional drawing and reverse re-drawing, were applied to the drawing of two kinds of steel wire rods called S35C and SWRCH6R. Then the residual stresses of the steel wire rod drawn by the two kinds of drawing processes were measured. The surface residual stresses to the axial direction of the steel wire rod were measured using X-ray analysis method. The result shows that there was a clear difference in residual stresses between unidirectional drawing and reverse re-drawing at nearly the total reduction 28 %. But beyond the total reduction 62 %, there was little difference in residual stresses. In addition the texture of the steel wire rod was observed using measuring method called Schulz reflection method which is one of the X-ray analysis methods.
