It is a common misconception than stainless steel does not corrode. It does. On its own in the environment it can be a very slow process, although is susceptible to crevice corrosion.
See link for a summary of corrosion.
http://en.wikipedia.org/wiki/Corrosion
With respect to contact with other metals, it depends on the metal. Look at the galvanic series and the lower (less noble) metal on the table is the one likely to corrode. The greater the difference on the table generally means a more aggressive reaction. The contact between metals does not have to be welded, it just needs to be enough for electrons to pass.

Stainless steel itself will not rust, unless it's a low grade of stainless. However, it is possible for surface rust to occur when in contact with easily corroded metals such as mild steel. There's no structural damage to the stainless, only cosmetic, and it can be buffed or polished away. Make sure if you use a metal brush that the bristles are also stainless, because if not, the surface rust will return in the future.

The short answer? A cheap one. While there have been some excellent answers - the Marine Shotguns, the Tennifer finished or the Black oxide over stainless sort of guns will hold up better, you have to really work to keep it clean no matter what you have. I've actually done different sort of salt water immersion and spray testing, (for my knife company and in my other professional work) and it really is remarkable how spray and temperature cycling manages to create corrosion sites on almost any steel. High polish and nickel coating helps, but if it can corrode it will in that environment eventually. Thinkingblade

Yes, stainless does corrode just go to a resturant and look at their kitchen equipment.

depends where it is , what environment its in, what the other metal is...
look at pontoons for house boats (mild steel) and out board motor legs ( alloy).. both are fitted with anode blocks ( sacrificial anodes)...these block are designed to corrode before the parent metal...
what grade stainless makes a huge difference to..
but the easy answer is yes.....electrolysis will cause corrosion..

NO, whatever joining the two metals together will corrode, say a weld unless the weld is also s/s

It depends on the metal, but in general that's why they call it "stainless" because it resists corrosion under most circumstances.

If it is good stainless it will not. To get good stainless use a magnet it will not attract stainless that has a high amount of nickle.

it will take surface rust from other metals but should not corrode its self unless welded

No ,that is why it is called stainless.If you weld it to another type of metal then yes.
