corrosion rated of uncoated steel
 

corrosion rated of uncoated steel
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,

1/8" per twenty years.
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.
