How much can stainless steel endure?

  • Hello everyone,

    I just came across a website about hardening stainless steel (-> in which they improve things like wear protection, corrosion resistance and other things. However, I was under the impression that stainless steel was pretty corrosion resistant to begin with? Why else would it be called STAINLESS steel? I thought stainless steel couldn't rust! This is why all of my kitchen tools are made of stainless steel after all... So the only explanation can be that it DOES corrode but under extreme circumstances, am I right?? Under which conditions does that happen? I'm curious!
