Can steel rust?

Answer 1

Yes if it is iron steel/

Answer 2

If it has iron in it then yes it will rust. Rust is a common name for Ferric Oxide (Fe2O3). However, since steel is a mixture of elements the rate at which it rusts is slower and thus its durability lasts longer.

This is why railroad tracks rarely need fixing or replacing, only the wood and gravel need to be regularly upgraded.

Answer 3

yep, even stainless steel can rust. Steel is a refined version of Iron. Iron Rusts.

Answer 4

Most forms of steel are prone to rust. Mild steel always comes covered in it. A few steel alloys, such as stainless steel are mixed with other metals such as magnesium and therefore are immune. Hence the name stainless.

Answer 5

Yes, even stainless steel will rust.

Answer 6

Yes,steel can rust.Resistance to rusting may vary depending upon the type of steel-cast steel,mild steel,alloy steel.Resistance can be increased by alloying elements like Ni,Cr,Mo and creating chrome oxide layer by passivation.

(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.

Iron is found naturally in the ore haematite 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.

Iron 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.

When steel contacts water, an electrochemical process starts. On the surface of the metal, iron is oxidized to iron(II):

Fe → Fe2+ + 2e−
The 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:

4e− + O2 + 2H2O → 4OH−
The 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:

Fe2+ + 2OH− → Fe(OH)2
4Fe(OH)2 + O2 → 2(Fe2O3.xH2O) + 2H2O
Hence, rust is iron(III)oxide, which is formed by the dehydration of iron(II) hydroxide. 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, by passivation. Rust can often be removed through electrolysis, however the base metal object can not be restored through this method.)

Answer 7

Yes, and cast iron, such as sewer pipe will last for 100 years or more in the ground. iron oxide will form as a protective coating.

Answer 8

Hi. Yes. Look at the exposed girders in a building or bridge.

Answer 9

yes

Answer 10

yes
