Titanium Tube



Heat Treatment

Titanium has a great thermodynamical affinity towards interstitial elements like Hydrogen, Oxygen, Nitrogen and Carbon. For heat treatment protective atmospheres like high vacuum or inert gases are suitable. The annealing temperatures range from 600 °C to 800 °C. The duration depends on the equipment, the type of process and the experience with the material. Organic residues such as lubricants should be completely removed prior to annealing. If they react with Titanium Hydrogen may be formed embrittling the material.

Tube Surface

Under most conditions Titanium and its alloys are covered by a thin but even oxide layer. If destroyed the material exhibits fretting corrosion. Vascotube® processing sequence includes high quality tooling, lubricants and heat treatment equipment.

We manufacture Titanium tubing according to ASTM F 67.
