Actually, I can't remember. 
I'm not even going to guess, but I do know it's considerably higher than the regular aluminum ones. And we all know how much abuse they can take and live to fight another day.

Technically yes. Practically... I don't have the money to find out! 
They can withstand higher temps, and steel also expands less than aluminum, so I'd hazard a guess that they'd last longer from that alone.
I guess the exhaust manifold wouldn't be too happy, or the valves... turbine maybe? Kinda depends on how much heat for how long a period. You know what they say, everything in moderation!

i cracked my original block and the $200 replacement has been sitting for years. it has some rust lips on the cylinder walls that are pretty deep.

Sorry, I digress. Here's a link to find a local store in your neighborhood that supplies Mahle pistons, rings etc. http://www.mahle-aftermarket.com/

You can get replacement pistons from Mahle, too. They have lots of pistons for the 5.9. Now you are gonna have to figure out wich ones you want. I'd use the non/IC version.
I don't even know if you can just go buy the monotherms, I think there is a waiting period.
I am pretty sure the valves are next in line of failure after the pistons.
If you read there ads, it says something like they "virtually eliminate piston failure". So for $3K they still won't guarantee it.
