Skin pass is another type of rolling process. Skin pass rolling is defined as a process in which fine structure give to the newly generated grain. After annealing process so that it become useful for forming operation. In case of skin rolling also known as a skin pass having less reduction around %.
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. the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the time of holding [35].
