Karl,
There are many, many different chain types for any given size and each
have their own use parameters. I use www.ustsubaki.com for my chain
solutions. Here is a tip, never use keyed sprockets for bi-directional
loads, as the keyways will eventually loosen. Tsubaki markets sprockets
with compression (friction) drive hubs and they are brilliant. Another
tip, metric and US standard chain sizes are practically interchangable and
that fact is never stated anywhere.

I'm trying to decide how large a roller chain I need...

Does anyone know of a table that shows how much each size roller chain
stretches under increasing loads?

The application is my plasma table. I'm upgrading from cable tension
drive to roller chain.

Just call up the nearest chain supplier and ask them the question.
They will have a set of specifications as long as your arm.
Some of the details will be of no value to you but a simple stress vs strain
would be somewhere near the top of the sheet
