All of them, to a greater or lesser degree, depending on their position in the "Electromotive Series of Metals," also known as the "Galvanic Series of Metals." This is a list of metals in order from most to least reactive in sea water. If there are two metals near each other in salt water, the one which is the more reacive (a.k.a. "least noble") will corrode, thus protecting the other metal. This is why ships often put chunks of zinc (called "zinc lozenges") near the propeller---without the zinc, the steel hull would corrode very quickly as it is more reactive than the bronze propeller. The zinc is more reactive than steel even, so it will do all the corroding and the hull is protected. Of course you have to replace your zinc lozenges periodically, as they will corrode away to nothingness eventually. Here is a simple one: From Most Noble (Protected Metals) to Least Noble (Corroded Metals): Mercury Vanadium Gold Silver Monel Nickel Passivated Stainless Steel (rare type) Copper Brass Tin Lead Active Stainless Steel (most common type) Cast Iron Steel Aluminum Zinc Magnesium You see that zinc is quite low on the list, and will corrode first and thus protect everything above it. Stainless steel is higher than ordinary steel---it stays stainless by forcing everything below it (like ordinary steel) to do the corroding. However, if you put stainless steel alongside nickel in salt water, the stainless will do the corroding and the nickel will be protected. Fancier lists include more metals and alloys of different metals.

The most common example is iron, with the presence of oxygen.
electrons
Corrosion of metal is caused by oxygen or oxidising substances, salty water and some medium strong acids
hydrogen
I dont think there is a metal stored under water because they react with water and instead are stored in kerosene or oil. Water often corrodes the metal producing rust so i cant think of any metal that would be stored under water.
base metal: a metal that oxidises or corrodes easily and i dont know what parent metal is..

The noble metals such as gold, silver, or platinum (etc.) do not readily corrode in salt water
This metal is iron.
hydrogen
The acidity of the alcohol corrodes the metal, "eating away" at it.
gold
platinum is a metal that never corrodes

when a metal bench is left outside in the rain it corrodes because some other metals in the reactivity series react fast with water

I do not think that water can corrode, can it?
