Corrosion.

When steel is exposed to the action of sea water and the weather it is said to corrode at the rate of an inch in eighty-two years; an inch of iron under the same conditions corrodes in 190 years. When exposed to fresh water and the weather the periods are 170 years for steel and 630 years for iron.
