It depends on the brand. Go to the manufacturer's website, it should list it. If you just want to get some idea the DiversDirect website has a decent selection.

There are lots of website with compilations of specs. You could start off with http://www.huronscuba.com/gear/cylinders.htm to figure out what steel 80 you are interested in, and then confirm the numbers with the manufacturers' websites.

What most people mean when they say "AL80" is shown on that chart as Luxfer 80 and Catalina S80. In other charts the most common Luxfer AL80 shows up as S080.
