ok Steve, I was wrong and your're wrong-headed, what the hell. In the
US we call that C-Mo steel and don't think too much of its properties.
Managese steel is a different animal, we make car crushing hammers
out of it.
In the US we call the alloy of which 531 is made "manganese molyobdenum"
and have done so since the 1930s. Your calling it something different
does not make it so, no matter how stubborn you are.

531 is the Reynolds brand name for their first grade of alloy
steel (Cr-Mo) high-strength tubing. It came in straight gauge
and double butted lengths of different thickness.

"...manganese–molybdenum, medium-carbon steel bicycle tubing...
The approximate alloying composition of 531 tubing is 1.5% Mn

So 531 denotes the mixture of metals in it?
It came in different configurations of butting and wall
thicknesses?
So people may be raving about the wall thickness, not so much
about the 531-ness itself?
