HEAT TREATMENT
- When maximum hardness, tensile strength, and fatigue resistance are required, annealing can be conducted at temperatures ranging from 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy offers versatile heat treatment options. - 1. Anneal: 1,275 - 1,400°F; (691 - 760°C), ½ to 2 hours, air or furnace cool.
- 2. Stress Relief Anneal: 1,000 - 1,200°F; (538 - 649°C), 1 to 8 hours, air or furnace cool.
- 3. Solution Heat Treat: 1,675 - 1,750°F; (913 - 954°C), 1 hour, water quench.
- 4. Aging: 975 - 1,025°F; (524 - 552°C), 4 to 8 hours - air cool.
In the solution-treated and aged condition, rapid quenching of smaller sections yields optimal properties. Larger sections and/or delayed quenching may not achieve the same level of properties.
HARDNESS
The typical hardness in the annealed condition is Rockwell C 30-34, while in the solution-treated and aged condition, it reaches Rockwell C 35-39.
Forgeability/Formability
- 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). For optimal properties, a minimum reduction of 35% is recommended.
- At room temperature, Ti-6Al-4V Grade 5 alloy bar is challenging to form, even in the annealed state. Severe forming operations like bending or stretching can be performed on annealed material at temperatures up to 1,200°F (649°C) without compromising mechanical properties. Hot sizing or forming can be achieved through creep forming within the range of 1,000 - 1,200°F (538 - 649°C).
Machinability
Ti-6Al-4V, Grade 5 alloy bar can be machined using techniques suitable for austenitic stainless steel, with slow machining speeds, high feeds, rigid tools, and ample non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod offers exceptional weldability in both annealed and partially aged conditions, with aging occurring during post-weld heat treatment. It is crucial to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding should be performed in an inert gas-filled chamber or with inert gas shielding the molten metal and adjacent heated zones, using a tail shield. Spot, seam, and flash welding can be performed without a protective atmosphere.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rods are susceptible to hydrogen contamination during improper pickling and to oxygen, nitrogen, and carbon contamination during forging, heat treating, and brazing. Such contamination can reduce ductility, negatively impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion resistance
Avoid using titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General corrosion
Table 1 details the general corrosion rates for Grade 2 titanium in various media. CP titanium boasts excellent corrosion resistance across numerous environments, including:
- Seawater and brines
- Inorganic salts
- Moist *** gas
- Alkaline solutions
- Oxidizing acids
- Organics and organic acids
- Sulfur compounds
Crevice corrosion
CP titanium offers superior resistance to crevice corrosion in salt solutions compared to stainless steels. It remains immune to crevice corrosion at temperatures below 80°C (176°F), regardless of pH, even under highly chlorinated conditions.
Stress corrosion cracking
Grade 2 titanium demonstrates excellent resistance to stress corrosion cracking (SCC) in hot chloride solutions and remains immune to SCC in seawater.
Erosion corrosion
Titanium exhibits exceptional resistance to erosion in flowing seawater at velocities up to 130 ft/sec (40 m/sec) with minimal impact on the material. Even with abrasive particles like sand, the corrosion effect is minimal.
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
Titanium shows no significant hydrogen absorption when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only if all the following conditions are met:
- pH is < 3 or > 12
- Temperature is above 176°F (80°C)
- A mechanism exists for hydrogen generation, such as a galvanic couple or impressed current.
Bio-corrosion
Titanium alloys exhibit unparalleled resistance to microbiologically influenced corrosion. Unlike many other materials, they do not show toxicity towards marine organisms, which can result in biofouling when exposed to seawater. This biofouling can be effectively minimized through chlorination or by increasing the water velocity within the heat exchanger.
Corrosion Fatigue
Titanium stands out among other materials for its consistent fatigue performance in seawater. Both its fatigue endurance limits and fatigue *** growth rates remain unchanged whether tested in air or seawater, ensuring reliable performance in marine environments.
Galvanic Corrosion
Positioned towards the noble end of the galvanic series, near stainless steels, titanium typically acts as the cathode when paired with other metals. As a result, titanium remains unaffected by galvanic corrosion while potentially accelerating the corrosion of the coupled metal. When titanium is paired with more noble metals like graphite, its passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod retains its fatigue properties even in the presence of seawater. Whether tested in air or seawater, its fatigue endurance limits and fatigue *** growth rates remain consistent, ensuring superior durability.
Weldability
CP2 Grade Titanium Rod offers excellent weldability, provided the necessary precautions are taken. Due to its reactivity, an inert gas shield must be used on both the OD and ID during welding. Additionally, the material must be free from any grease or oil contamination to ensure a quality weld.
Grade 2 Titanium Rod is typically welded using manual or automatic TIG welding, with or without filler wire. Employing low heat input minimizes the heat affected zone, and post-weld heat treatment is generally not required for Titanium Rods.
