I ordered some .020 4130 sheet about12x36

I notice the writing on the sheet runs parallel to the 12" edge.
Do I understand then that the grain of the steel is parallel to the
12"edge?
If I plan on bending this sheet, is there harm in bending across the
grain? - Mike

Other than the parts cracking, no problem.

Look at the metal. You can SEE the grain.
