Will stainless steel, when in contact with another metal, corrode?

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. http://en.wikipedia.
