stainless steels are specials grades of steel with a minimum of 10% chromium. tool steels also contain chromium but they differ from the fact that the stainless steels have very low percentage of carbon. presence of carbon is a negative factor because chromium has high affinity to carbon and oxygen. chromium carbide is undesirable , only chromium oxide is necessary as it forms the thin layer referred to as the passive film. chromic oxide is very stable oxide that forms spontaneously on stainless steels upon exposure to air. this thin layer must be uniform, continuous, and free from defects for corrosion resistance. the passive film hence formed should not be disturbed in any case else corrosion becomes inevitable.there many processes like pickling, passivating,mechanical and electrochemical cleaning performed to remove any rust so that the passive film is uniform to prevent corrosion.

Well, the answer lies in the question; by saying 'real' stainless steel, you are implying that there are fake metals which go under the name 'stainless steel', thus the difference is that the stainless steel in refigerators is actually stainless steel, and the fake stainless steel is not...thus your question is answered...

True stainless steel will not rust.

Chromiun is the primary metallic element added to steel to make stainless steel.
Stainless steel, particularly grades like 316 and 304, are the most resistant to rust due to their high chromium content. The chromium forms a passive layer on the surface that protects the steel from corrosion.
Phosphoric acid can decrease the corrosion resistance of stainless steel by promoting the formation of localized corrosion, such as pitting and crevice corrosion. This is due to the acid's ability to break down the protective passive film on the stainless steel surface, making it more susceptible to corrosion.
Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents surface corrosion. Stainless steel will not be effect by temperatures pass 100 degees Celcius (212 Fahrenheit) at which temperature water boils.
Yep, you can weld steel to stainless and you can weld stainless to steel. You can use steel or stainless welding rod in either case but the steel or steel welding rod will of course rust.
No, Stainless steel is not porous. Steel how ever is.

Steel and stainless steel tend to weigh around the same, however, stainless steel can sometimes be a bit lighter.
