We have both HT and non-Heat Treated SILVER tubing...and one of my BLAHG posts within the last 5 weeks had an explanation. On the Taiwan frames we use non-HT tubes, which are better (for reasons explained in the post). For the American frames we use HT, because there's a belief (that I don't buy) that HT is better, and if we use nonHT on frames that cost $2K+, some people will say, "Aha!" for the wrong reason. Our Taiwan frames are tested rigorously, vigorously, to tough standards and they pass. When tested TO DESTRUCTION, they don't fail because of insufficiently strong tubing.
UTS (Ultimate Tensile Strength) is the "glory score" of bike frame tubing, but oddly so, because it literally, actually, is a measure of the force required to pull the material apart in tug-o-war...and that is not how bike frame tubes are stressed. But it correlates with other forces that ARE imposed on ridden bike frames...but the correlation isn't perfect and is misleading...as the BLAHG post stated. I am not in proper mental/emotional/wrist pain from typing state right now to dig in and find that post, but ... it's out there, and what I've said here is the short version. All good fun things to discuss!
