Can silicon steel rust like normal iron?

Others have had similar problems and solved them.  See the link.  In general, metals (especially iron and its alloys) rust when exposed to moisture in the presence of oxygen.  The rust is a loose collection of molecules that allow more moisture and oxygen to reach the base metal.  For example, you can shine aluminum but it will quickly dull with oxidation.  The aluminum corrosion however forms a tenacious film that protect the metal from additional corrosion.  I heard that copper (flashing?) on a rooftop can cause aluminum gutters to corode.  Various alloys of iron (steel) including heat treatments may impart various corrosion properties, however, chrome is usually added to form stainless steels that best resists rusting.  Silicon steel may have to be protected.  Good luck.

Try Wikipedia...the link is below:\nhttp://en.wikipedia.org/wiki/Rust\n\nBut generally speaking:\n-Iron rusts to form Iron Oxide (Fe2O3)-numbers are all in subscripts\n- Aluminium oxides forming Aluminium Oxide, which is concidered as rust as well\n\nNot all metals rust the way iron does

they will rust. metal does that when it gets cold have water on it.

errrrrrr Oxygen, hence rusting is stricly called oxidisation.  But perhaps you should inform your questioner that Water is actually made up of Hydrogen and Oxygen, therefore some of the answers are obsolete.\n\nThink about the fact that metalwork inside a waterproofed building goes rusty as well as that outside.

Depends on the metal. Most metals generally become brittle. Iron on the addition of Carbon hardens. You may say option 2.

Stainless steel contains chromium that was put there by diffusing it in there with high heat and a concentration difference.  Metals corrode because they get converted from neutral, solid form to ions (they are oxidized, that's why oxidation is a synonym for corrosion) that combine with negatively charged ions (usually oxides or chlorides) and are no longer metal, and many times soluble, hence taking a chunk out of your original metal.  Chromium is a more active metal than the iron that makes up most of the steel.  This means when both are present on the same surface, the chromium is more likely to dissolve into ions and electrons than the iron.\n\nWhen stainless is exposed to dissolved oxygen in water (for example) the chromium atoms will dissolve their way towards the surface of the steel. Then, they will be oxidized:\n\nCr(s)-->Cr3+ + 3e-\n\nWhat little iron that may have been oxidized before the chromium reached the surface can gain these 3 electrons and join the surface as solid iron again.  Otherwise, once the Cr reaches the surface, it'll corrode to form chromium oxide, a greenish black powdery ceramic that doesn't stick well to the surface, and can be easily rinsed away or knocked off.  And while the Cr will be oxidized, the iron will not because the Cr is more active. The steel itself remains shiny and well, stainless (without rust).  However, when the steel runs out of Cr atoms to sacrifice to protect the iron (once they become chromium oxide, they won't go back to being regular Cr metal, and the oxide does NOT stick to the surface to protect it), the iron will rust.

Yes, they do. The simplest example I can do is Fe (iron): it's a transition metal and has 3 oxidation states: 0 (Fe as a metal), +2 (FeO), and +\n3 (Fe2O3).

1) Depends on environmental conditions\n2) Oxidation of iron--- 2Fe + 3O2---> 2Fe2O3\n3) Not easily.  To remove rust, phosphoric acid (naval jelly) is good\n4) Ultimate weapon: Cadmium plate, epoxy primer, epoxy finish coating.

That depends on the alloy of steel you are talking about. The term alloy is almost always used incorrectly these days, especially amongst bicyclists. They use the term to mean aluminum. What the term alloy really means is a mixture of metals, any kind of metals. Almost all metal used today is a mixture and therefore an alloy.\n\nMost steel has other metals added to tune its properties, like strength, corrosion resistance, or ease of fabrication. Steel is just the element iron that has been processed to control the amount of carbon. Iron, out of the ground, melts at around 1510 degrees C (2750°F). Steel often melts at around 1370 degrees C (2500°F).

Rust is usually defined as a red or brown oxide coating on iron or steel caused by the action of oxygen and moisture. So rust is defined by the oxide coating. There are also methods of corrosion that involve things other than oxygen, but I don't think it would be classified as rust.

Rust is the substance formed when iron compounds corrode in the presence of oxygen and water. It is a mixture of iron oxides and hydroxides. Rusting is a common term for corrosion, and usually corrosion of steel.\n\nIron is found naturally in the ore hematite as iron oxide, and metallic iron tends to return to a similar state when exposed to air, (hydrogen, oxygen, nitrogen, etc) and water. This corrosion is due to the oxidation reaction when iron metal returns to an energetically favourable state. Energy is given off when rust forms. The process of rusting can be summarized as three basic stages: The formation of iron(II) ions from the metal; the formation of hydroxide ions; and their reaction together, with the addition of oxygen, to create rust.\n\nIron is the main component of steel and the corrosion of steel is observed more frequently, since iron is rarely used without alloying in the present day.\n\nWhen steel contacts water, an electrochemical process starts. On the surface of the metal, iron is oxidized to iron(II):\n\n    Fe → Fe2+ + 2e-\n\nThe electrons released travel to the edges of the water droplet, where there is plenty of dissolved oxygen. They reduce the oxygen and water to hydroxide ions:\n\n    4e- + O2 + 2H2O → 4OH-\n\nThe hydroxide ions react with the iron(II) ions and more dissolved oxygen to form iron oxide. The hydration is variable, however in its most general form:\n\n    Fe2+ + 2OH- → Fe(OH)2\n    4Fe(OH)2 + O2 → 2(Fe2O3.xH2O) + 2H2O\n\nHence, rust is hydrated iron(III) oxide. Corrosion tends to progress faster in seawater than fresh water due to higher concentration of sodium chloride ions, making the solution more conductive. Rusting is also accelerated in the presence of acids, but inhibited by alkalis. Rust can often be removed through electrolysis, however the base metal object can not be restored through this method.\n\nHydrated iron oxide is permeable to air and water, meaning that the metal continues to corrode after rust has formed. The iron mass eventually converts entirely to rust, and disintegrates.

A metal's corrosion (rusting) rate depends on its chemical properties. Some metals just take longer than others to corrode. Keep in mind that most metals have very high melting temperature, so in general high temperature doesn't contribute to the corrosion of a piece of metal just sitting in a damp space. For temperature to be of concern, it has to be around 700 degrees Celsius.\n\nI don't know much about your experiment, but you might not be using an appropriate metal sample. Most commonly found metals come with coatings or contain chemical inhibitors to prevent corrosion. Think about bikes sitting in outside in a humid (moisture-rich) environment. Manufacturers have to coat the metals to prevent this corrosion, or else no one would buy their product. This is the case with most metals. So if you just picked up something laying around the house and tried to corrode it, your experiment might not be successful. You should also be aware that only ferrous (iron) alloys rust, and the particular metal you tested might be something else.\n\nGo to google and type "rusting metal" (without the "s). The first four sites have lots of info.\n\n*It wouldn't rust in the freezer because there's no moisture in the freezer.

Steel is an alloy of carbon and iron.  If you want stainless steel, throw in some Chromium, too.

As the above answerer states, you don't need to - titanium won't rust; rather it develops a protective, inert oxide layer in air, just like aluminum has it's protective  inert oxide layer - Al2O3.\nIron and steel rust/oxidize in air and it can prevented by giving a coating of zinc, chromium, or magnesium on it.

Aluminum DOES rust; it just isn't like iron rust. Aluminum oxide (chemical formula Al2O3) forms a thin film on the outside of the aluminum. \n\nSome people say, figuratively, that we have never really seen aluminum, because the oxide coating forms so quickly; (I have to disagree with what someone else wrote above) you can't scratch aluminum and then see the true color before the oxide covers it.\n\nAl2O3 is chemically the same as sapphire, it is very hard and strong. Once the coating has formed on the surface, it protects the rest of the aluminum in the bulk of the piece, so it doesnt corrode away. The coating is very thin, though-- only one molecule thick-- so we don't notice it and it doesn't really add any structural strength to the aluminum. \n\nBy contrast, iron rust is very weak. It crumbles and falls apart very easily; it can't even support its own weight. So it breaks off the surface of the iron and leaves fresh iron exposed to rust. That is why bridges and girders fall alart if they are not painted or protected from the elements. But aluminum protects itself.

Are you talking about steel? If so, each one has his own set of possible problems. Most of it depends on chemistry and what the end use is going to be. Take a look at ASTM and API specifications. You might find your answer there. A metallurgist can answer your question.
