The annual cost of corrosion in USA
alone is estimated to be about 300 billion US$ or 4.2% of GNP as
shown by 1995 update of the 1975 study by Battelle.
-
At least 35% of the above amount could have been saved by taking
appropriate corrosion control measures.
-
In UK, the corrosion cost is
estimated to be 4-5% of the GNP.
-
In Japan, the cost of corrosion is
estimated to be 4 Trillion Yen per year.
-
For industrialized nations, the average corrosion cost of 3.5-4.5%
of the GNP. The cost is down from 4.9% in 1975.
Below are some startling figures about corrosion losses:
-
The cost of corrosion in civilian and military aircrafts is about
13 billion US$.
-
The annual cost of corrosion in developed nations is a staggering
4-5% of GNP. About 30-50% per year could be saved by using corrosion
control techniques.
-
The corrosion-free life of automobiles in the coastal regions of
Arabian Gulf is about 6 months only.
-
Nearly 95% of concrete damage in the Arabian Gulf coastal region
is caused by reinforced corrosion and spalling of concrete.
-
Major corrosion losses to the tune of £350 million in transport,
£280 million in marine, £250 million in buildings and
construction, and £180 million in oil and chemical industries, have
been reported from UK.
-
About $120 billion is spent on maintenance of aging and
deteriorating infrastructures in USA. Over 50% of USAF fleet is more
than 20 years old. Some of them are designed for service until they
are 70-80 years old. USAF corrosion costs are $0.25 to 1 million per
plane.
-
Automotive corrosion in USA costs $94 billion.
-
Every new born baby in the world now has a corrosion debt of $35.
