So I got couple of steel. And they arrived not flat, what should I do in this situation and anyway to flat it by myself? Thank you

If it's hardened grind it flat, if not bend it straight.

Just hammer it flat on an anvil. If you don't have an anvil a piece of wood will work.

Be sure to do normalizing/stress relief when doing HT.
