The Néel temperature for steel is typically somewhere around 200 -- 500 ºC depending on the alloy. Steel that is hot enough to "fuse into a lump" will need to be significantly hotter than that -- nearly at the melting point. All of the magnetic information will have been wiped. Other ferromagnets useable for magnetic recording are going to behave similarly. Cheers, Matthew
