Depending on the resolution of the stl file, you lose information about round part. You can devide a round part in a lot of different triangles to make it seem round, but it never will be round. Stl files (and other mesh files) will store points and vertices which represent plains. But if you said that you did various checks, it probably is ok. In freecad in the Mesh Design workbench under the mesh -> analize menu there is an evaluate and repair mesh feature.
