β-titanium alloy, annealed and air-cooled to room temperature, almost all β-phase titanium alloys.
Annealing and air cooling to room temperature are almost all titanium alloys in β phase.
The β-phase stabilizing elements are four grades: titanium molybdenum vanadium and titanium vanadium aluminum. Depending on the brand, the range of performance changes is: tensile strength 690～1400MPa.
It is smelted in a vacuum consumable electric arc furnace. Used as rivets, fasteners, flying mechanism frames and rockets, etc.
