Evaluation of Stainless Steel Culvert Pipe in Mahaska County, Iowa, HR-2001

Corrosion of culvert pipe in Iowa in general is not a serious problem. However, it is potentially significant in some local areas.

The potential of stainless steel pipe is to reduce maintenance costs that are incurred through replacement and upkeep. A new stainless steel material, Allegheny Metal MF-1, was used in a partial fabrication demonstration and later these demonstration sections were delivered to the selected field site for placement
