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?

In: Engineering

Answer 1

You might think that steel is something nearly indestructible. It’s not. With sufficient amount of forces, even metal can be warped or pressed like clay. This requires infrastructure, but its worth it

Cold rolling is using rollers to compress the metal at a certain temperature, which caused it to have its molecular structure changed, making it harder, less plastic, and stronger.

So yes. In a sense it is like the glass roller.
