Description

TiAl6V6Sn2 with the material number 3.7174 (see also TiAl6V6Sn2, material number 3.7175 according to DIN 17851-90) belongs to the hardenable alpha + beta-titanium alloys. It is similar to the 3.7164 or 3.7165 (TiAl6V4), yet the ß-phase is more stable and the material shows higher strength. TiAl6V6Sn2 is applied in the form of bars and forgings in the annealed as well as in the hardened condition (up to a thickness of 50 mm). Sheets and plates are used in the annealed condition. TiAl6V6Sn2 possesses good resistance to corrosion, it is well forgeable, the long-term application temperature is approximately 350 °C. Processing properties: Formability: limited (cold forming), good (hot forming) Weldability: : limited (embrittlement of the welding and heat affected zone by transformation hardening, electron-beam welding)
