Iron goes molten at 2,800f. The air friction would have caused that long before getting to space. As for staying together and resolidifying in space…well imagine how well maple syrup would stay held together if you threw it out of a cup pretty hard. The iron would have went molten and just proceeded to “spatter” and not have any piece left heavy enough to keep up an escape velocity.
