Don't equate the "no grain flow" of the first example with no grain. There is grain. It's just random because it hasn't been hot rolled to give the grain direction. I'm just starting to get my head around the concept but there is a certain type of grain that is set by rolling it at the mill and then there is grain that forms and reforms along the intercrystal boundaries in random directions. Kevin Cashen wrote up something about grain not too long ago that explained it much better than I can. I'm just not sure that it was on this board. Try googling something like steel grain + Kevin Cashen and see what you can come up with.
