The article describes why stainless steel is stainless and also why
stainless steel often isn't stainless in certain environments.

It also describes the some of the different formulae for stainless steels. One
thing it doesn't make clear is the fact that each of the different types of
stainless is susceptible to different types of corrosion and immune to others.
The type which is called "CRS" by the USN is relatively benign in a marine
environment. Other types may pit badly or otherwise corrode.
