Optimal Heat Treatment Procedures
- For applications requiring high hardness, tensile strength, and fatigue strength, annealing is performed at 1,700-1,900°F (927 - 1,038°C).
The DAXUN 6-4™ Grade 5 alloy is versatile in its heat treatment processes. - 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 solution treated and aged conditions, rapid quenching of small sections yields optimal properties. Larger sizes or delayed quenching may result in suboptimal characteristics.
Achieving Ideal Hardness
Typical hardness in the annealed state ranges from Rockwell C 30-34, and Rockwell C 35-39 in the solution and aged condition.
Forgeability and Formability Excellence
- 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 reduction of 35% is recommended.
- The Ti-6Al-4V, Grade 5 alloy bar, renowned for its remarkable properties, presents formidable challenges when forming at room temperature, even in an annealed state. However, this alloy excels under extreme conditions: bending or stretching operations can be seamlessly performed on annealed material at elevated temperatures up to 1,200°F (649°C) without compromising its mechanical properties. For those requiring hot sizing or forming, creep forming within the range of 1,000 - 1,200°F (538 - 649°C) offers an efficient solution.
Machinability
The Ti-6Al-4V, Grade 5 alloy bar showcases impressive machinability using austenitic stainless steel techniques. Employ slow machining speeds, high feeds, and rigid tools, complemented by generous applications of non-chlorinated cutting fluids to achieve optimal results.
Weldability
Welding the Ti-6Al-4V, Grade 5 alloy rod is a straightforward process, whether in the annealed condition or in the solution and partially aged state. Aging is effectively achieved during post-weld heat treatment. It is crucial to prevent contamination with oxygen, nitrogen, and hydrogen. Fusion welding can be performed within an inert gas-filled chamber or using inert gas to shield the molten metal and adjacent heated zones. Tail shields aid this process. Spot, seam, and flash welding are also feasible without a protective atmosphere.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rods must be handled with care to avoid contamination. Improper pickling can lead to hydrogen contamination, while forging, heat treating, and brazing may introduce oxygen, nitrogen, and carbon. Such contamination can reduce ductility, negatively impacting notch sensitivity and forming properties.

Grade 2 Titanium Rod
Superior Corrosion Resistance
Note: Avoid using titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion Attributes
Table 1 showcases general corrosion rates for Grade 2 titanium across various media. CP titanium boasts remarkable corrosion resistance against a broad spectrum of environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion Resistance
CP titanium outshines stainless steel in salt solutions' crevice corrosion resistance. It remains unaffected at temperatures below 80°C (176°F) regardless of pH, even under extreme chlorinated conditions.
Stress Corrosion Cracking Immunity
Grade 2 titanium excels in resisting stress corrosion cracking (SCC) in hot chloride solutions and is SCC-immune in seawater.
Erosion Corrosion Defiance
Titanium demonstrates superior resistance to erosion within flowing environments.
Seawater exhibiting velocities up to 130 ft/sec (40 m/sec) shows negligible impact on our titanium materials. Even with abrasive particles, such as sand, the corrosion effect remains minimal.
Hydrogen Embrittlement
Significantly, titanium exposed to seawater does not absorb hydrogen, even at elevated temperatures. Hydrogen absorption typically occurs only under the following specific conditions:
- 1. pH levels are < 3 or > 12.
- 2. Temperature exceeds 176°F (80°C).
- 3. An enabling mechanism for hydrogen generation is present, such as a galvanic couple or an impressed current.
Bio-Corrosion
Titanium alloys exhibit an exceptional immunity to all forms of microbiologically influenced corrosion. While they do not exhibit toxicity toward marine life, potentially leading to biofouling in seawater, this can be effectively controlled by chlorination or increasing water velocity through heat exchangers.
Corrosion Fatigue
Unlike many other materials, titanium maintains its fatigue performance in seawater. Fatigue endurance limits and *** growth rates are consistent whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is positioned near the noble end close to stainless steels. Thus, it typically acts as a cathode when coupled with other metals, avoiding galvanic corrosion itself but potentially accelerating corrosion in the other metal. Coupling with more noble metals enhances titanium's passivity.
Fatigue Properties
Grade 2 Titanium Rod stands out by not showing degradation in fatigue properties when exposed to seawater. Its fatigue endurance limits and *** growth rates are the same whether tested in air or seawater.
Weldability
The CP2 Grade Titanium Rod offers excellent weldability when proper precautions are adhered to. Given titanium's reactivity, an inert gas shield is required on both the OD and ID of the rod, and the material must be free from grease or oil contamination.
Grade 2 Titanium Rods are 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 not usually required.
