I glued up a “slab” for a coffee table because I didn’t have wide enough boards. This was from a beech I’d taken down several years before. I made up legs with stretchers from 1 1/2” pipe. Instead of using pipe flanges (which seemed too big for the scale of the table) I welded square plates to the tops of the legs. When I first screwed them in place, a crack started forming very soon. So I filed the screw holes into an oblong shape and refastened, leaving the screws just snug enough to prevent wiggling, but not so tight as to prevent wood movement. The incipient crack then went away, and it has worked fine since.

The slab is not reinforced with an apron. This doesn’t seem to be a problem

Screws in slotted holes is my go-to solution.

The easiest approach imo is to attach two
battens with slotted screw holes to the
bottom of the slab. Then the batten ends
can be fastened to the base. The method
avoids making slotted screw holes in steel.

Use a 3/4” NPT tap to tap a blind hole directly into the slab, if it’s thick enough. Assuming your ‘steel base’ is iron plumbing pipe.
