United Bicycle Institute of Ashand, Oregon, uses Kaisei tubing.
Their store site explains the differences between each of Kaisei's offerings:

UBI leaves off Kaisei 4130R. Seems to have roughly equivalent specs to Kaisei 8630R, though I see it rarely. I'm supposing both are heat-treated, but what is the difference? Can anyone vouch for 4130R's liveliness, springiness, stiffness, ride quality???

All of those attributes vary based on frame design, tubing diameter, and thickness of the tubes....the 4130/8630/whatever designations mean nothing in that context.
The thinner, lighter tubes are made from different steel alloys because they they need to be stronger because they are....erm... thinner and lighter! ;)

This is a perfect question for one of the less used parts of this forum. Im sure the guys and gals in the framebuilders (http://www.bikeforums.net/forumdisplay.php/229-Framebuilders) section will be much more knowledgable and usefull than the collective here will.

It's funny how many street riders geek out over fancy tubing when Mr.Yamaguchi uses 4130 and Hi-ten for his $1700 street fixie frame.
