Nope! It can tarnish some, from being in contact with rusted steel against it, but will usually wash/sand/scrub right off

It is called stainless for a reason. Exactly as bear mentioned.
It is always more valuable, and sells as non ferrous per lb.

yes it can rust..301 series will and it will also draw to a magnet
|
so will 304.
But, a quick wipe with a rag will brush it off - at least it does on the stainless submersible pumps I've scrapped.

Agreed with above...depends on the grade. Also steel parts attached to it will leave rust marks that will buff out most times.

If it has rust and it is non magnetic should still go in with stainless. I have had them check when they see rust spots and still got stainless price...

Saltwater will corrode and eat stainless after a while......Mix a glass of saltwater and throw a stainless piece of silverware in it and see how long it lasts.

This is from Wikipedia:
Stainless steel does not corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity, or poor circulation environments.[3] It is also called corrosion-resistant steel or CRES when the alloy type and grade are not detailed, particularly in the aviation industry. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and resistance to corrosion are required.
316 Stainless or as it is often called "marine grade stainless" is used in adverse conditions such as salt water to prevent corrosion. It contains more nickel then 304 stainless (the most common flavor), and therefore is worth more per pound.
