This kind of reminds me of something I was curious about awhile back.
Mentioning pressure vessel reminded me of it.  Who knows what steel is used
for gas cylinders?  Some gasses are stored under tremendous pressures, and I
am sure that the steel is probably of high quality because of the safety
factor needed for some stored gasses.

Don't know th esteel but the ends of these cylinders make great bells. 
I have one from some smaller O2 cylinders, just right for a bell. If 
you use these cut them with a hack saw in case they had something 
flammable (read explodable) inside.

The books I use for welding say they use armor plate steel for high
pressure cylinders. They are cast or forged and then the neck is either
swegded or spun. The cast cylinders are generally the older ones, and boy
are they heavy!
