How can stainless steel corrode?

All “ stainless ” steels can corrode under the wrong conditions. Remember that most of the metal is still iron and can corrode or rust depending on how much stress it is exposed to. One of the worst things you can do to stainless steel is expose it to chlorides. The better grades can withstand a lot of abuse, but most grades can eventually fail when exposed to chlorides in bad atmospheres. Some grades of “stainless” steel have very poor resistance to corrosion. They are marginally better than carbon steel, but when correctly hardened and passivated or electropolished can give fairly good performance. The grade of steel must reflect the exposure conditions and performance required.

What are the elements that make stainless steel resistant to corrosion?
