HEAT TREATMENT
- For applications requiring high hardness, tensile strength, and fatigue strength, annealing can be done at temperatures ranging from 1,700-1,900°F (927 - 1,038°C).
The versatile DAXUN 6-4™ Grade 5 alloy can undergo various heat treatments to achieve desired properties. - 1. Anneal: 1,275 -1,400°F (691 - 760°C), ½ to 2 hours, followed by air or furnace cooling.
- 2. Stress Relief Anneal: 1,000 -1,200°F (538 - 649°C), 1 to 8 hours, followed by air or furnace cooling.
- 3. Solution Heat Treat: 1,675 -1,750°F (913 - 954°C), 1 hour, followed by water quenching.
- 4. Aging: 975 -1,025°F (524 - 552°C), 4 to 8 hours, followed by air cooling.
In the solution-treated and aged condition, rapid quenching of small sections yields optimum properties. Larger section sizes or delayed quenching may result in properties that are less than optimal.
HARDNESS
Typically, the hardness in the annealed condition is Rockwell C 30-34, and it ranges from Rockwell C 35-39 in the solution-treated and aged condition.
Forgeability/Formability
- Ti-6Al-4V, Grade 5 alloy bar is forged at a temperature of 1,750°F (954°C) with a final forging temperature of 1,450°F (788°C). A minimum of 35% reduction is recommended to achieve optimal properties.
- Ti-6Al-4V, Grade 5 alloy bar is challenging to form at room temperature, even when annealed. Therefore, severe forming operations like bending or stretching should be performed on annealed material at temperatures up to 1,200°F (649°C) without affecting mechanical properties. Hot sizing or forming can be achieved by 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 methods applicable to austenitic stainless steels. This includes slow machining speeds, high feeds, rigid tools, and the liberal use of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is renowned for its exceptional weldability in both the annealed condition and the solution and partially aged condition, with aging completed during post-weld heat treatment. It is crucial to avoid contamination from oxygen, nitrogen, and hydrogen. Fusion welding must be conducted in an inert gas-filled chamber or with inert gas shielding to protect the molten metal and adjacent heated zones. Spot, seam, and flash welding can be executed without a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to contamination from hydrogen during improper pickling, and from oxygen, nitrogen, and carbon during forging, heat treating, and brazing processes. Such contamination can lead to a reduction in ductility, negatively impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Exceptional Corrosion Resistance
Avoid using titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion Characteristics
Refer to Table 1 for the general corrosion rates of Grade 2 titanium in various media. CP titanium offers robust corrosion resistance across a multitude of environments, including:
- Seawater and brines
- Inorganic salts
- Moist *** gas
- Alkaline solutions
- Oxidizing acids
- Organics and organic acids
- Sulfur compounds
Crevice Corrosion
CP titanium demonstrates superior resistance to crevice corrosion in salt solutions compared to stainless steels. It remains unaffected by crevice corrosion at temperatures below 80°C (176°F) regardless of pH, even under highly chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium boasts excellent resistance to stress corrosion cracking in hot chloride solutions and remains immune to SCC in seawater.
Erosion Corrosion
Titanium exhibits outstanding resistance to erosion in flowing
seawater at velocities up to 130 ft/sec (40 m/sec) with negligible impact on the material. The presence of abrasive particles, such as sand, has minimal 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 of the following conditions are met:
- pH is < 3 or > 12
- Temperature exceeds 176°F (80°C)
- A mechanism exists for hydrogen generation, such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys possess an exceptional resistance to all types of microbiologically influenced corrosion. Owing to their non-toxicity towards marine life, biofouling may occur in seawater environments. This can be effectively mitigated through chlorination or by increasing the velocity of water flowing through heat exchangers.
Corrosion Fatigue
Titanium stands apart from many other materials by maintaining its fatigue performance even in seawater. The fatigue endurance limits and *** growth rates of titanium remain consistent whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is positioned near the noble end, close to stainless steels, typically acting as the cathode when paired with other metals. Consequently, titanium remains unaffected by galvanic corrosion but can accelerate the corrosion of less noble metals. When coupled with more noble metals such as graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod exhibits unique resilience, showing no deterioration in fatigue properties even when exposed to seawater. The fatigue endurance limits and *** growth rates are identical whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable, provided the necessary precautions are observed. Given titanium's reactivity, an inert gas shield must be applied to both the outer and inner diameters of the rod. The material should also be free from any grease or oil contamination.
Grade 2 Titanium Rod is commonly welded using manual or automatic TIG welding techniques, with or without filler wire. To minimize the heat-affected zone, low heat input is recommended. Typically, post-weld heat treatment is not performed on titanium rods.
