Abstract ��The formability of bake hardened steel (thickness 0��82 mm), and the extra galvannealed IF steel (thickness 0��82 mm) have been studied. The suitability of the above steels for forming applications has been critically examined. The microstructure, tensile properties, and formability parameters of the above sheet metals were determined. The manufacturing process of the steels and the significance with reference to its formability were studied.
