Specifications
AMS 4928 - Bars, Forgings, and Forging Stock (Annealed)
AMS 4965 - Bars, Forgings (Solution treated and aged)
AMS 4967 - Bars, Forgings (Annealed, Heat Treatable)
Advanced Heat Treatment
- For optimal hardness, tensile strength, and fatigue strength, annealing can be conducted at 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. Delayed quenching or larger section sizes may result in suboptimal properties.
Hardness
Typical hardness ranges from Rockwell C 30-34 in the annealed condition and Rockwell C 35-39 in the solution and aged condition.
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). A minimum reduction of 35% is recommended to achieve optimum properties.
- The Ti-6Al-4V, Grade 5 alloy bar is known for its challenge in forming at room temperature, even in its annealed state. However, demanding forming processes such as bending or stretching can be successfully executed on annealed materials at elevated temperatures up to 1,200°F (649°C) without compromising mechanical properties. Hot sizing or forming is achievable through creep forming within the temperature range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar is machinable using methods designed for austenitic stainless steel. This requires slow machining speeds, high feeds, and rigid tooling, along with the generous use of non-chlorinated cutting fluids for optimal results.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod exhibits exceptional weldability in both the annealed state and the solution and partially aged state, with aging typically achieved during post-weld heat treatment. Ensuring contamination prevention from oxygen, nitrogen, and hydrogen is crucial. Fusion welding is feasible within an inert gas-filled chamber or using inert gas to weld the molten metal and adjacent heated zones, paired with a tail shield. Additionally, spot, seam, and flash welding are possible without the necessity of a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to hydrogen contamination from improper pickling and to oxygen, nitrogen, and carbon contamination during forging, heat treating, or brazing. Such contamination can lead to a loss in ductility, adversely 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 various media are shown in Table 1. CP titanium demonstrates excellent corrosion resistance in a broad range of 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. CP titanium does not exhibit crevice corrosion at temperatures under 80°C (176°F) regardless of pH, even in super chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium provides excellent resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion
Titanium shows excellent resistance to erosion in flowing environments.
Seawater with velocities up to 130 ft/sec (40 m/sec) shows negligible impact on the material. Even abrasive particles such as sand have only a minor effect on its corrosion resistance.
Hydrogen Embrittlement
Titanium exposed to seawater does not significantly absorb hydrogen, even at elevated temperatures. Typically, hydrogen absorption occurs only under the following conditions:
- The pH is < 3 or > 12
- Temperature exceeds 176F (80C)
- A mechanism for hydrogen generation exists, such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys exhibit unique immunity to microbiologically influenced corrosion. However, biofouling can occur in seawater, as titanium alloys do not show toxicity toward marine organisms. This can be mitigated by chlorination or increasing water velocity through the heat exchanger.
Corrosion Fatigue
Unlike many other materials, titanium does not exhibit reduced 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 towards the noble end near stainless steels and typically acts as the cathode when paired with other metals. Thus, titanium remains unaffected by galvanic corrosion but may accelerate corrosion in the other metal. Pairing titanium with more noble metals like graphite further enhances its passivity.
Fatigue Properties
Grade 2 Titanium Rod maintains its fatigue properties in seawater, showing no degradation. Fatigue endurance limits and *** growth rates are consistent whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable with appropriate precautions. An inert gas shield must cover both the OD and ID of the rod due to titanium's reactivity. The material must be free from grease or oil contaminants.
Grade 2 Titanium Rod is typically welded using manual or automatic TIG welding, with or without filler wire. Low heat input is recommended to minimize the heat-affected zone. Post-weld heat treatment is generally not required for Titanium Rod.
