Good job. But banding is a more complex phenomena to explain solely by the rolling process, it also involves chemical segregation of some elements in the composition of the steel.

Thank you sir

Yes sir it is a big subject to be discussed.Banding is due to the presence of segregations like MnS inclusions.I will put a separate video on that.
