VT6 - grade 5 medical titanium pipe
General characteristics
Titan brands VT6S, VT6 belong to the group α+β alloys. They are made according to GOST 19807−74, 90013−81 OST. Alloy VT6 legarrette 6% Al + 4,5% V, and alloy VT6S — 5% Al + 4% V. Aluminum is able to consolidate the α+β phase, the vanadium contributes to the stabilization of β-phase and impedes the formation of superstructure alpha-2 in α-phase… Aging and hardening increase the strength level by 15 — 20% while maintaining a fairly high plasticity. Option cast alloy ВТ6Л.

Heat treatment
Brand VT6 is used in heat-strengthened and annealed condition. Annealed alloy contains in its composition up to 10% β-phase. The presence of aluminum contributes to hardening of the α and β-phase. Aging and hardening increase the strength level by 15 — 20% while maintaining a fairly high plasticity. Brand VT6 high-tech in the processing pressure. ВТ6кт containing a lower percentage of impurities is used at cryogenic temperatures up to -196°C.
