Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the time of holding [35].

The thickness of the hot-rolled strip is important in that the properties of the final cold rolled and annealed product is influenced by the percent of cold reduction. This means that the thickness of each hot-rolled coil is carefully controlled to provide the mill with a specific thickness to achieve the proper percent cold reduction.
