"Interesting fact all steels become austenitic and will not attract a magnet at around 1480f as the carbon content starts to go into solution"

True enough, and the temperature at which carbon steel no longer attracts a magnet is called the "Curie Point". Additionally, nickel is ferromagnetic, although only about 20 percent that of carbon steel. A good bar bet is to state that nickel is magnetic; most will argue with you since their experience is with the U.S. 5-cent coin, wich is not nickel. A Canadian 5-cent coin, which IS nickel, will be attracted by a magnet.
