On the surface of stainless steel an ultrathin layer of chromium oxide after the contact with oxygen; this layer has the role of protection against rusting.

Is an Ammonium hydroxide and hydrogen peroxide mixture compatible with stainless steel?
Yes - it is oxidizing. Stainless steel is "stainless" because of the tough adherent Chromium oxide film. It needs oxygen to remain stainless.
What are the stainless steel properties?
Hard and does not rust, 20% iron, 20% chronium, 9.5%nickel, 0.5% carbon.
How stainless steel become stainless?
All stainless steel has at least 10.5% Chromium in it. Chromium is what makes the steel stainless. The other elements in stainless steel can be nickel, nitrogen, molybdenum. You can find more information here: http://www.wisegeek.com/what-is-stainless-steel.htmIt is the incorporation of a good bit of chromium that makes steel into stainless steel. The presence of chromium in steel alloys allows them to resist chemical attack better than "regular" steels.Stainless steel contains chromium. The chromium forms a protective oxide layer on the metal surface. Even when scratched or cut, a new chromium oxide layer will form in stainless steel.
Is chromium added to steel to make stainless steel?
a varying amount. stainless steel can be a variety of formulations. In general the more corrosion resistant the steel is the higher the chromium content.
Why are other metals added to stainless steel?
Stainless steel is an alloy of steel and chromium. The chromium is added for what is called passivation -- that is, to make passive or unreactive. When the chromium metal in stainless steel meets air, it forms a very thin layer of chromium (III) oxide. This layer is inert, impermeable to water, and extremely resistant to all forms of corrosion (since it is already oxidized). It protects the inner structure of the steel from rust cavities, since it prevents oxidation in the iron itself. Stainless steel is easily sterilized, and any harsh treatments that remove parts of the material are met with innate regeneration of the protective chromium oxide layer. These properties make it ideal for biological uses, such as eating utensils and surgical instruments, and for uses where corrosive materials are present, such as industrial process equipment that deal with acids.Though it is the chromium that makes stainless steel, there are many grades of stainless steel which many contain a few other additives. Nickel is the most widely-used one, which is used to make the metal less brittle. Most stainless steel products contain considerable amounts of nickel. Other additives are manganese, which is typically used more or less as a substitute for nickel, and molybdenum, which adds strength, thermal resistance, and corrosion resistance to the stainless steel.
Do the stainless properties of stainless steel disappear if it is melted and reused?
Stainless steel remains stainless after recycling. It resists rusting primarily because of the chromium content of the alloy. The chromium oxidizes to form a protective layer. The formation of this oxide layer is improved by a process called passivation. There are different grades of stainless steel having varying proportions of chromium, nickel and other elements so if you want to get top-dollar for stainless steel scrap, you need to segregate it.
How do stainless steel and aluminium react similarly in air?
neither of them corrodes. Both of them are passivated, in stainless steel it is a film of chromium oxide, in aluminium a film of aluminium oxide.

How do you make stainless steele?
Stainless Steel contains between 10 1/2 and 11% Chromium. The layer of Chromium Oxide keeps the steel from rusting. It's interesting to note that Stainless Steel is called that because it "Stains Less". That does not mean that is is stain PROOF.
What is the difference between stainless steel and normal steel?
stainless steel has chromium added to the steel, which forms a protective oxide layer at the surface, preventing corrosion (rust).
Does Stainless steel corrode at different water temps?
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.
What is the compound name for Cr2O?
chromium oxide
Why does chromium in stainless steels make them more corrosion?
learn your grammar It doesn't it forms a layer of chromium oxide to protect the metal from water and air that makes the iron in the steel corrode
Does stainless steel contain iron or iron alloys?
Yes, quite a bit of it. It also contains Chromium, which prevents rust by forming a protective oxide layer.
Why does chromium in stainless steels make them more corrosion resistant in many environments than plain carbon steels?
Chromium forms a tough, adherent ,extremely corrosion resistant, oxide - chromium oxide on the surface. It is the chromium oxide that is extremely corrosion resistant. It also adheres extremely well. Iron oxide - rust does not adhere well - all to do with the Pilling-Bedworth ratio. It is also why Aluminum is very corrosion resistant. It forms a thin adherent layer of aluminum oxide on the surface.
