For WW2 tank armour, what about the “rolling” that made the steel better than cast armour hardened armour and how… do you roll a steel plate?

Question

I’m familiar with the use of rollers to make glass panes but surely it’s not that?

Answer 1

Steal has a grain to it similar but not as extreme as how wood has a grain to it. If you forge or roll steel you can control that, and you can make a product that is a higher quality materials. If you cast a metal you just pour the molten metal into a cast and you get whatever you get. You could heat and cool after casting but there’s no way to reshape the metal.
