I don't think we need to go overboard here. Do get the socket checked. Replacement is a good precaution, it had passed a large current will not have done it (or the wring to it) any good. It could be as bad as needing the cables replaced but I suspect not. Aqualified electrician could put your mind at ease.
In a mention of what I'd do, not what I'm advising, and which may be a little lacking in H&S, I'd replace the plug and see if the f/f still had an issue. I'd probably, maybe, replace the wall socket to be on the safe side. And I would investigate why the fuse/mcb (possibly even the rcd) didn't "blow". That does seem strange. They are there to protect the circuit, and they failed.
