Abstract
This research include a practical study on the effect of pre-annealing in different conditions and the number of forming steps on the formability of low carbon steel sheet of thickness(10)mm which is widely used due to popular industrial uses especially in the cold pressing processes. A particular specimens were annealed at different temperatures then a set of tests were applied on these specimen. It was noticed that the annealing improve the ductility of the specimens especially the temperature that equal to 550°C with (12) minute soaking time which gave the best ability of cold pressing for the specimen . Also it was found that use of two steps of cold pressing with annealing between improve the formability of the specimen as compared with the single step of cold pressing.
Key words :annealing , steel , forming , cold pressing , ductility.
