Non-Magnetic Cast Iron, or some magical metal?

 · Non-Magnetic Cast Iron, or some magical metal? Was asked to make some drawings of a casting, about 100lbs, heavy thick rust all over. I assumed some sort of cast-iron, until I went to put a magnet to it (ND42sh) and it fell off, magnet sticks to it about as little as it does to a piece of 304 round bar, so it ain''t much.
