Dry Indoors Location |
<1.3 micrometers |
<0.1 micrometers |
|
Desert Location or Urban Area (non polluted) |
1.3 to 25 micrometers |
0.1 to 1.5 micrometers |
|
Mild Marine/Mild Industrial Location |
25-50 micrometers |
1.5 to 6 micrometers |
|
Marine Location (Calm Sea) |
50-80 micrometers |
6-20 micrometers |
|
Marine Location (Beach Surf) |
80-200 micrometers |
20-90 micrometers |
Notes: 1 millimeter is subdivided by 1,000 micrometers.
Example: A 100mm thick carbon steel plate left to rust just a few hundred meters inland of a beach (Mild Marine Location), would take about 27,000 years to completely corrode away to nothing. However, for a vehicle like a tank or APC, water would tend to get trapped in certain areas, leading to a higher corrosion rate in those regions. But the vehicle would still remain recognizable as what it was for a very long time.
