Overheating 753 tubing destroyed the advantage of the heat treatment, but left it essentially the same as 531 "Special Lightweight." Working the material was different from untreated steel -- mitering the tubes wore out files and saw blades at a prodigious rate, but cutting on a lathe was ok once we started building to a standard geometry (the first frames we built were custom designed team frames). And 753 does not cold set. It just doesn't. You either build it straight from the start or toss it and start over.

I have heard that Francisco Cuevas insisted that he could build 753 frames using brass instead of silver, and suffered a high failure rate as a result.
