Your forgeting that cast iron is porous and it would leak over time. Most axle castings are stored inside. An axle is not a place where you would want dirt and worse getting into the axle casting. I inspected axles at Dana and a spec of dirt would halt the production lines. I've inspected JD cut axles to Cat axles that were 22 feet from hub to hub. Axle castings get treated very well in the world of part storage and I could not see any company that would store them out side without some sort of plastic wrapping to keep then clean and dry. If they did they would have had to be cleaned before use and that adds to cost and time.
