Stainless steel is ferrous as it contains iron. A lot of stainless steels are partially magnetic. You can actually look at the part and tell if it is steel or stainless. If it is nice and silver colored with no corrosion then it is probably stainless. My steel turnbuckles are mostly a broken black color from a black oxide coating at the factory. Both steels willl look similar after a sanding or polish. Polished steel with no oil will tend to oxidize right before your eyes in Houston and develop a light brown stain.

Stainless steel will most likely be non-magnetic. In order for steel to become stainless, chromium is added when making the metal. Because the amout of chromium is so high compared to the amount of iron, stainless steel usually loses its magnetic properties.
