i have a very nice steel fork that i was going to install on my bike, but i just discovered this:

it is the inside of the steerer. Those two lines seem to be cracks. What do you think?
The steerer is steel. It is powdercoated inside. So it might be just the powdercoat thing but I can not really inspect it because it is only on the inside of the steerer. There are no marks or imperfections on the outside.
