I kind of like this sander a lot because it is so small. I have a hand
held electric sander also. All good ideas.

I have had to flatten a few 2"-5" pieces of mild steel recently.

FWIW, here is what works for me:
1) Sanding attachment in angle grinder - 40, 80, 120, 220 grit till I am
happy it is flat
2) Clean up with *palm* sander 60 (sometimes skip), 120, 220, 320, 400 grit.
3) I love my 4x36" belt sander but for this job it did not work as well as
the above.
