Prometheus is best known for defying the gods by stealing fire from them and giving it to humanity in the form of technology, knowledge, and more generally, civilization Prometheus is known for his intelligence and for being a champion of humankind.

Sandvik Special Metals.

From former Sandvik division manager:

For what it's worth, I can add a bit of insight into that frame material. I used to be a North American manager for Sandvik USA through the1990's, although I ran a different division (I was in Strip Steel line). I can assure you that the Titanium tubing used in the sports division was as good as you can get. You see, the plant was in Kennewick, Wa. because they serviced the nuclear industry there. They needed something to do with the small remnants of left-over tubing, so they started the sports division, making bike frames, golf club shafts, and hockey stick shafts (which they had to stop for player safety-they were TOO indestructible). As the tubes were designed originally to carry nuclear waste and other harsh stuff for infinite periods of time, you can assume that you will never have an issue with corrosion or material breakdown of any kind.

This is from Bike Pros
Titanium alloy Ti-3Al-2.5V,is the titanium alloy that Sandvik Special Metals has made so famous, in tubing form, in the bicycle industry. Sandvik is a maker of seamless tubing from ingot of this alloy. They will sell the tubing to small parts makers to be re-manufactured into bicycle components. More commonly, Sandvik is contracted to re-manufacture the titanium tubing on behalf of the bicycle parts maker to the maker's specifications, for a contracted price. Sandvik's tool set and titanium fabrication experience is probably un-paralleled, and our examination of their work has shown flawless quality in the miter cuts and joining welds. Sandvik sells and uses Ti-3Al-2.5Vtubing that has been cold worked to increase the materials strength. To reduce the residual stress left after cold working, the tubing is then "stress relieved" which is a process of heating the metal to a suitable temperature, below melting or "recrystallization", and holding this temperature long enough to reduce the residual stress of the cold work, then cooling it slowly enough to minimize the development of new residual stresses.
