Should 100% stainless steel never rust?

Loved the wheeler dealer episode where Ed says his stainless won't rust because its stainless and there is no iron in its makeup!...I think thats how he said it . I know what he meant but was funny....but I forgive him because of everything else I've learned from him.

My mate told me not to use steel spanners on stainless....either stainless spanners or chrome.

I thought he was having a laugh....but I looked it up and he was right. I think it causes contamination which can lead to rust!

Stainless steel is usually chosen for its corrosion resistant properties, but it is important to know that different grades provide different amounts of corrosion resistance. Austenitic stainless steels generally provide the most corrosion resistance because of their high amounts of chromium. This makes grade 304 an excellent choice when corrosion resistance is important. Grade 316 is similar to grade 304, but it has molybdenum as part of its chemical makeup, further increasing its corrosion resistance. Ferritic stainless steels and martensitic are generally more affordable than austenitic stainless steel because they have less nickel and sometimes less chromium than austenitic stainless steels, which can result in a loss of corrosion resistance.

Basically, as long as there is sufficient chromium present, the chromium oxide layer will continue to protect the stainless steel and prevent it from corroding.
