I dunno about anyone else, but I think the idea of bell-curve bolt strength is marvelous............"ooooh, be careful of those things, they look really shiney and new!" hahahhahahhaha
Then again, I reckon the greatest acheivement of australian climbing, perhaps even world climbing, was the seatbelt-as-pro concept which Mikl pioneered. So I understand that others may not see the awesomeness of bell-bolts
I believe that the volume increase in by a factor of just over 9.
The change from Fe to Fe2O3.(nH2O) causes an increase in volume due to a combination of oxidation, hydration and the re-alignment of the chemical constituents. Steel generally has densely packed atoms with a strong alignment of its crystalline structure (depending on the production process). Hence its high weight per volume. Hydrated iron(II) oxide, or rust, has a very loose crystalline structure. The H2O component is not permanently bound to the Fe2O3 and is a significant factor in volume increases.

wild guess on my part, sorry
Magnetite is a different oxidation state (Fe2+?), I wouldn't have thought it would occur on climbing gear, but look at this piton with wierd concoidal fracures in the 'rust'
