THE
EFFECT OF ENVIRONMENT ON THE CORROSION OF METALS IN SEA WATER- -A LITEATURE
SURVEY - This report is the first phase of a research program intended
to investigate the effects of physical, chemical, and possibly biological
factors present in natural environments on the deterioration of metals,
particularly mild steel. Such a study will provide knowleige that can lead to
improved techniques for protection of metals against the degrading effects of
different natural environments. The Appendix presents an outline of a very broad
program, within which practically any research and evaluation study on the
deterioration effects of natural environments on materials can be placed. It is
included to show the reader the part this particular literature survey and its
logical extension to new laboratory research in areas not yet covered, can play
in the total picture of material deterioration. This literature survey is
concerned with the corrosion of metals end alloys submerged in sea water which
is, of course, a very corrosive solution. Historically, the corrosion of
materials in the marine environment has been of great importance. It is not
surprising that many studies have been made to evaluate the performance of
metals and alloys in various marine environments.Materials
for Seawater Pipeline Systems - Choice of
material for seawater pipeline systems will depend upon the particular
environmental situation and the nature of the application. It will be affected
by availability, price and political considerations, as well as the life
expectancy; previous performance in similar situations will also influence the
decision. Of the materials considered in this paper, 90/10 copper-nickel is the
one most widely used and most likely to fulfil the majority of requirements for
the futureSea

The
corrosion behaviour of a low carbon steel in natural and synthetic seawaters: The corrosion behaviour of a low
carbon steel was investigated in natural seawater and various synthetic
seawaters. It was found that the steel corroded nearly four times faster in a
3.5% NaCl solution than in natural seawater for an exposure time of 21 days. The
corrosion rate after immersion in synthetic seawaters (ASTM D1141 and Marine
Biological Laboratory seawater) is similar to the corrosion rate after immersion
in natural seawater.Guidelines

Vessels and equipment built for service in seawater and other marine environments must employ fasteners that are resistant to corrosion by the aggressive service conditions to which they are exposed. Contractors and fabricators who build ships for the U.S. Navy must recognize this requirement, as a structure is no stronger or more reliable than its weakest member. Failure of a nut or bolt can have catastrophic results.
