Q:Do stainless steel pipes corrode?

Sure. Stainless steel is better than normal steel but is not corrosion-resistant.

So, either you know that a particular grade of stainless steel (yes, there are many types/grades of stainless steel) is suitable for a particular application based on already documented knowledge (handbooks, etc. for example) or you test the stainless steel and generate data. Standard corrosion test protocols give a metallurgist a lot of information about the probability of a particular grade of stainless steel being suited for service.

Contrary to the name stainless steel is not stainless, it is stain-resistant.

There are many varieties of stainless steel alloys with varying corrosion resistance, alloys of iron, chromium, nickel, and other materials in lesser amounts. Various specific combination formulas have been given names/numbers.
