Long ago, I was told by one who used both tubing that Reynolds was more forgiving to braze.
The production bikes got Reynolds, the Specials, Columbus.

I was disappointed that only two measurements were made per temperature and that an average of two measurements was reported.
It seemed more like a pilot study to me, not one powered enough to produce conclusions.
It would have been nice to see a table of the actual data or the pair of points to produce each average.
I wonder if his thoughts held up over time.

Very interesting thanks!
531 starts to lose strength at about 1900F, some way before the melting point of steel (2500F) but the SL appears to be more stable. Would be good to see the graph all the way up to 2500.
This is what we would expect because SL is cromoly and we know you can weld that.
It seems odd that back in the day anyone was worried about overcooking SL with any sort of brazing (or now for that matter).
