HEAT TREATMENT
- For applications requiring high hardness, tensile strength, and fatigue strength, annealing can be performed at temperatures between 1,700-1,900°F (927 - 1,038°C).
The DAXUN 6-4™ Grade 5 alloy can undergo various heat treatment processes. - 1. Anneal: 1,275 -1,400°F; (691 - 760°C), for ½ to 2 hours, followed by air or furnace cooling.
- 2. Stress Relief Anneal: 1,000 -1,200°F; (538 - 649°C), for 1 to 8 hours, followed by air or furnace cooling.
- 3. Solution Heat Treat: 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.
In the solution treated and aged condition, rapid quenching of small sections maximizes properties. However, larger sections or delayed quenching may result in suboptimal properties.
HARDNESS
The typical hardness in the annealed condition is Rockwell C 30-34, whereas in the solution and aged condition, it is approximately Rockwell C 35-39.
Forgeability/Formability
- The Ti-6Al-4V, Grade 5 alloy bar is forged at 1,750°F (954°C) with a final forging temperature of 1,450°F (788°C). To achieve optimal properties, a minimum of 35% reduction is recommended.
- The Ti-6Al-4V, Grade 5 alloy bar is challenging to form at room temperature, even in the annealed state. Therefore, severe forming operations such as bending or stretching should be performed on annealed material at temperatures up to 1,200°F (649°C) to maintain mechanical properties. Hot sizing or forming can be achieved through creep forming in the range of 1,000-1,200°F (538-649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar can be machined using methods suitable for austenitic stainless steel, involving slow machining speeds, high feeds, rigid tools, and large quantities of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is exceptionally weldable, whether in the annealed state or partially aged condition. Aging is seamlessly integrated during post-weld heat treatment. It's imperative to guard against contamination by oxygen, nitrogen, and hydrogen. Fusion welding can be conducted within an inert gas-filled chamber, ensuring molten metal and heated zones are shielded. For spot, seam, and flash welding, a protective atmosphere is not mandatory.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod may undergo hydrogen contamination from improper pickling, and oxygen, nitrogen, and carbon contamination during forging, heat treating, and brazing. Such contamination could lead to loss of ductility, negatively impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion resistance
Titanium should not be used with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General corrosion
The general corrosion rates for Grade 2 titanium in a variety of media are shown in Table 1. CP titanium exhibits good corrosion resistance to a wide variety of environments including:
- Seawater and brines
- Inorganic salts
- Moist *** gas
- Alkaline solutions
- Oxidizing acids
- Organics and organic acids
- Sulfur compounds
Crevice corrosion
CP titanium exhibits good resistance to crevice corrosion in salt solutions compared to stainless steels. CP titanium will not exhibit crevice corrosion at temperatures under 80 °C ( 176°F) regardless of pH, even under super chlorinated conditions.
Stress corrosion cracking
Grade 2 titanium shows excellent resistance to stress corrosion (SCC) cracking in hot chloride solutions and is immune to sec in seawater.
Erosion corrosion
Titanium shows excellent resistance to erosion in flowing
seawater with velocities up to 130 ft/sec ( 40 m/sec) showing negligible effect on the material. The presence of abrasive particles, such as sand, has only a small effect on corrosion.
Hydrogen embrittlement
There is no significant absorption of hydrogen into titanium exposed to seawater, even at higher temperatures. Normally hydrogen absorption occurs only when the three following conditions are met:
- pH is < 3 or > 12
- Temperature is above l 76F (80C)
- A mechanism exists for hydrogen generation such as a galvanic couple or impressed current.
Bio-corrosion
Titanium alloys have shown unparalleled immunity to all forms of microbiologically influenced corrosion. Their non-toxic nature towards marine organisms does allow biofouling in seawater, which can be effectively minimized through chlorination or by enhancing water velocity through heat exchangers.
Corrosion Fatigue
Titanium stands out among many materials for maintaining its fatigue performance even in seawater. Whether tested in air or seawater, its fatigue endurance limits and *** growth rates remain consistent.
Galvanic Corrosion
In the galvanic series, titanium's position near the noble end close to stainless steels ensures it usually acts as the cathode when paired with other metals. This means titanium is unaffected by galvanic corrosion, although it may accelerate corrosion in the coupled metal. When paired with more noble metals like graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod is exceptional as it retains its fatigue properties even in seawater. Its fatigue endurance limits and *** growth rates are the same in both air and seawater environments.
Weldability
CP2 Grade Titanium Rod is highly weldable with the right precautions. Due to titanium's reactive nature, it requires an inert gas shield on both the OD and ID of the rod. Additionally, the material must be free from grease or oil contamination.
Grade 2 Titanium Rod is typically welded using manual or automatic TIG welding, with or without filler wire. To minimize the heat affected zone, low heat input is recommended. Post-weld heat treatment is generally not required for Titanium Rod.
