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.
Why is ferrous alloy has more corrosion resistant then iron?
An alloy is a mixture of metals and a ferrous alloy is an alloy who's main constituent is iron. Iron in itself is extremely susceptible to corrosion, however, with the addition of other metals to create a ferrous alloy, such as the addition of slag (Such as in wrought iron), Nickel (Alnico, Invar, etc), Maganese (Bismanthol), Chromium (Kanthal), Titanium (Ferrotitanium) and so on give the alloy it's corrosion resistance. So, in short, almost, if not all ferrous alloys contain a constituent that is corrosion resistant, hence why ferrous alloys are more resistant to corrosion that straight iron.
What is platinum in its pure form?
It is a whitish, highly-malleable metal but with hardness equal to iron and highly resistant to corrosion. When impure, as with osmium or rhodium, it is more brittle.
Does the brass corrode?
Yes Brass can corrode especially if coupled to a more noble metal in which case it will undergo Galvanic Corrosion. Amines and Nitrogen containing compounds can cause Stress Corrosion Cracking.
What is steel corrosion resistance?
whichever substance that neutralises or reacts with chromic oxide will corrode stainless steel. search for chemical properties of chromic oxide. stainless steel is considered as a "corrosion resistant alloy" that means that is more resistant than the common steel to corrosion. a typical corrosion reaction is when stainless steel is incontact with fluid that contains chlorides, like seawater, and small pit are produced.
Why are alloys more resistant to corrosion than pure metals?
They are not always. Pure metals like gold never rust. Aluminum is also very corrosion resistant and its alloys not necessarily more so. Chromium is another metal that is extremely corrosion resistant and is alloyed with Iron and carbon to make a type of stainless steel.
What material is better - stainless steel or carbon steel?
It depends on the applications. Stainless Steel is more corrosion resistant and more expensive. Carbon Steel is cheaper and less corrosion resistant.
What is the Metal is corrosion resistant?
Well the way you phrased your question is that one is more than another but actually there are multiple such as Nickel,Aluminum,and Gold. Whitch are all equally corrosion resistant.
What happens to galvanised iron which is exposed to air and water?
It is more resistant to corrosion.
How do you protect construction steel bars from corrosion?
the concrete cover protects the steel bars from corrosion and environments or members more prone to corrosion or chemical attack such as in footings the cover thickness is increased in members where the concrete will come to direct contact with the soil a blinding layer of about 10cm is used to separate the reinforced concrete from the soil. also coating steel bars in corrosion resisting chemicals is used for more protection
Why is aluminium used in airoplanes?
because it is ductile, malleable and more importantly light weight and resistant to corrosion

What is the difference between steel and staniless steel?
Stainless steel contains a minimal of 13% chromium and is much more corrosion resistant.
What is nonferrous?
Non Ferrous metals are those metals which do not contain iron.They are not magnetic and are usually more resistant to corrosion than ferrous metals.
What is the main advantage of stainless steel over mild steel?
Many stainless steels are stronger. It's also more corrosion resistant.
Is a brass faucet easy to keep clean?
Brass will oxidize and turn greenish. Moen and Delta have PVD brass finishes which are more resistant to corrosion.
