Corrosion rated of uncoated steel

[71corvette]

Can anyone provide generally accepted anticipated rates of corrosion for uncoated steel exposed to the elements? I realize the rates of corrosion will vary based on a myriad of environmental criteria, but are there some basic ranges of corrosion rates that can be provided?

Thanks,
Tim

Try the piling code

In a typical environment corrosion rates have been determined at: 0.008in/yr.

In more corrosive environments rates extend to 0.012in/yr.

You can find this information in many FHWA or NCHRP references.
