That sounds a lot like 312 Stainless which is marketed as a superalloy by a number of vendors. A discussion here on stainless fillers for various steels suggested that 309 is almost as strong, less subject to cracking and much cheaper. 309 runs around 95Kpsi. Try it.

What, if any, is the advantage of ER80S-B2 over 309 or 312 SS?

Thanks, I'm pretty pleased with it. Very comfortable, even by recumbent standards, and efficient enough to make the most of my meager power output.
Yes. Designing recumbents and recumbent accessories (and building some of the accesories myself) is my part-time, semi-retirement occupation. I make enough to support my bike and tool addictions.
There is still some question about stainless steel alloy filler metals and stress fractures.
Personally I use Hastelloy W for most steel welding unless a color match is needed.
They're interesting things to watch. There's one in my town, and the guy who owns it attracts a lot of attention. Kids follow him all over town.
I've never ridden one, but I've always been curious about them. Maybe I'll try one some day.
