Featuring a low density and a commendable strength-to-weight ratio, CP 2 grade titanium tubes are ideally suited for applications demanding weight reduction without compromising strength. These tubes are cold formable, exhibit good ductility, and can be welded using standard TIG and MIG processes with inert gas shielding to prevent embrittlement in the weld zone.

Crystal Structure

At room temperature, ASTM B338 Grade 2 titanium tubes exhibit an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. At around 885°C (1625°F), they transform into a beta (body-centered cubic) structure. The transformation temperature can vary based on impurities or alloying elements. The addition of alloying elements divides the equilibrium transformation into two temperature zones: the alpha transformation zone (below which the alloy is all alpha) and the beta transformation zone (above which the alloy is all beta). Between these zones, both alpha and beta forms coexist. Typical alpha and beta transformation temperatures for Grade 2 titanium are 890°C (1635°F) and 913°C (1675°F), respectively.

When high hardness, tensile strength, and fatigue strength are required, DAXUN's Ti-6Al-4V Grade 5 Titanium Tube is expertly annealed at 1,700-1,900°F (927-1,038°C).
DAXUN's 6-4 Grade 5 Titanium Tube is versatile and can undergo various heat treatments.
1. Annealing: 1,275-1,400°F (691-760°C) for ½ to 2 hours, followed by air or furnace cooling.
2. Stress Relief Annealing: 1,000-1,200°F (538-649°C) for 1 to 8 hours, followed by air or furnace cooling.
3. Solution Heat Treating: 1,675-1,750°F (913-954°C) for 1 hour, followed by water quenching.
4. Aging: 975-1,025°F (524-552°C) for 4 to 8 hours, followed by air cooling.

Optimum Properties

Maximum properties are achieved with small cross sections and rapid quenching in the solution-treated and aged condition. Larger cross sections or delayed quenching may result in less than optimal properties.

Hardness

Typical hardness values for the annealed condition are Rockwell C 30-34, while the solution-treated and aged condition yields approximately Rockwell C 35-39.

Forgeability/Formability

The DAXUN Ti-6Al-4V Titanium Tube, which is Grade 5, showcases exceptional forging characteristics. It is ideally forged at temperatures of 1,750°F (954°C) with a finishing forging temperature of 1,450°F (788°C). For optimal results, a reduction of at least 35% is highly recommended.

The DAXUN Ti-6Al-4V Titanium Tube, Grade 5, presents challenges when forming at room temperature, even post-annealing. However, intense forming operations like bending or stretching can be effectively performed on the annealed tube at elevated temperatures up to 1,200°F (649°C) without compromising its mechanical integrity. Additionally, creep forming is an excellent method for hot sizing or forming, operating efficiently between 1,000 to 1,200°F (538 to 649°C).

Machinability

The DAXUN Ti-6Al-4V Titanium Tube, Grade 5, is amenable to machining using techniques similar to those applied to austenitic stainless steels. Optimal machining requires slow speeds, high feeds, robust tool rigidity, and a substantial application of non-chlorinated cutting fluids to ensure precision.

Weldability

The DAXUN Ti-6Al-4V Titanium Tube Grade 5 is highly weldable in both annealed and solution-treated, partially aged conditions, with post-weld aging enhancing its properties.

To prevent contamination by oxygen, nitrogen, and hydrogen, strict precautions must be observed. Fusion welding can be achieved in an inert gas-filled environment or by using an inert gas tail shield over the molten weld and adjacent hot areas. Additionally, spot welding, seam welding, and flash welding can be performed effectively without a protective atmosphere.

Special Considerations

It is crucial to avoid hydrogen contamination in the DAXUN Ti-6Al-4V Titanium Tube, Grade 5, which can occur due to improper pickling or from the absorption of oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such contamination can significantly reduce ductility, negatively affecting notch sensitivity and formability.
