The samples were packed with stainless steel sheet to improve their workability. The hot rolling was performed on a two-high mill with the rollers of 360 mm in diameter and 600 mm in length at a nominal rolling speed of 0.43 m/s. The samples were preheated at a fixed temperature about 733 K for 0.5 h.
roll. Other attributes such as the generation of "mill fines" during the rolling process and the retention of the oil on the sheet, applied after rolling, during transport and storage. The forming process considers such factors as formability, coefficient of friction, and resistance to "scoring" and "galling" as important performance
