Re: Replace old galvanized 2in waste pipe with PVC
It's more likely fitted with lead than with concrete. But yes, a hammer and chisel is the way to do it.
When fitting in the new pipe, once you've got the hub cleaned out on the vertical stack, you can use a rubber "donut" to join the new pipe to the existing stack.
Another alternative is to saw off the 2" pipe a few inches from where it joins the stack, then use a rubber coupling to join the new pipe to the old.

I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
