Calculating Corrosion Rates, steel piles

[FCCBCCHCP]

I was wondering if there were any formula's availible for calculating the corrosion rate of steel in soil. I had a question from a client about the corrosion rate of steel piles in the Fort Macmurray area. I took a look at NACE RP0502-2002 and there is an assumption of 16mpy for base steel but is there a better way to be a little more precise.

any help is appreciated.

FCCBCCHCP;
Nothing that I have seen in literature. In most cases, actual coupon testing is preferred, otherwise, go with the 16mpy.


You might want to add BCT in the above.

I suggest you to make assumption using literature data.

I've found this links on the net, just make a search with 'soil corrosion' in my site or google,i think they can be useful for you.
