Steel sheets frequently exhibit pronounced textures influencing the product properties by causing anisotropies. In the present paper a survey is given of the typical textures in steel sheets in the final and also in the intermediate stages of the manufacturing process. In order to quantify and characterize textures the method of ODF is used, which also allows a simple representation of the main texture features by plotting the pole density along texture fibres. For hot‐rolled strip the textures of mild unalloyed and high‐strength microalloyed steels are considered for different finish‐rolling temperatures including rolling in the γ/α dual phase region. Besides the textures in the middle‐section the surface textures are also dealt with. The cold‐rolling texture is investigated with regard to the influence of hot‐band texture and grain size for unalloyed mild deep‐drawing grades and IF‐steels. The recrystallization texture of different deep‐drawing qualities is presented together with results of the influence of N‐fixation on the texture determined r‐values.
