SPECIFICATIONS
AMS 4928 - Bars, Forgings, and Forging Stock (Annealed)
AMS 4965 - Bars, Forgings (Solution Treated and Aged)
AMS 4967 - Bars, Forgings (Annealed, Heat Treatable)
HEAT TREATMENT
- For high hardness, tensile strength, and fatigue strength, annealing is performed at 1,700-1,900°F (927 - 1,038°C).
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, 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
Rapid quenching of small sections in the solution treated and aged condition yields optimum properties. Delays or larger sections may result in suboptimal properties.
HARDNESS
Typical hardness ranges: Annealed condition - Rockwell C 30-34; Solution and aged condition - 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). A minimum reduction of 35% is recommended to achieve optimal properties.
- The Ti-6Al-4V, Grade 5 alloy bar is known for its challenging formability at room temperature, even when annealed. However, severe forming operations such as bending or stretching can be effectively executed on annealed material at elevated temperatures up to 1,200°F (649°C) without compromising its 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 can be expertly machined using methods designed for austenitic stainless steel. Employ slow machining speeds, high feeds, and rigid tools, along with a copious application of non-chlorinated cutting fluids to achieve optimal results.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod offers excellent weldability in the annealed state, as well as in the solution and partially aged conditions. Aging can be completed during post-weld heat treatment. It's crucial to prevent contamination by oxygen, nitrogen, and hydrogen. Fusion welding can be performed in an inert gas-filled chamber or with inert gas shielding for the molten metal and adjacent heated areas, using a tail shield. Spot, seam, and flash welding can also be performed without a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to contamination by hydrogen from improper pickling and by oxygen, nitrogen, and carbon during processes such as forging, heat treating, and brazing. Such contamination can lead to a loss of ductility, adversely affecting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion Resistance
Titanium is unsuitable for use with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion
Grade 2 Titanium exhibits excellent general corrosion resistance in various media, as shown in Table 1. CP titanium resists corrosion in many environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organic Compounds and Organic Acids
- Sulfur Compounds
Crevice Corrosion
CP titanium offers superior resistance to crevice corrosion in salt solutions compared to stainless steels. It withstands temperatures up to 80°C (176°F) without crevice corrosion, regardless of pH, even under super chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium displays excellent resistance to stress corrosion cracking (SCC) in hot chloride solutions and remains immune to SCC in seawater.
Erosion Corrosion
Titanium showcases excellent resistance to erosion in flowing environments.
In seawater conditions with velocities reaching up to 130 ft/sec (40 m/sec), our titanium material shows negligible impact. Even the presence of abrasive particles such as sand has only a minimal 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 these three conditions:
- 1. pH is < 3 or > 12
- 2. Temperature exceeds 176°F (80°C)
- 3. A mechanism for hydrogen generation exists, such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys exhibit exceptional immunity to all forms of microbiologically influenced corrosion. They do not exhibit toxicity towards marine organisms, leading to potential biofouling in seawater. This can be mitigated by chlorination or increasing water velocity through the heat exchanger.
Corrosion Fatigue
Unlike many materials, titanium does not experience reduced fatigue performance in seawater. Fatigue endurance limits and *** growth rates remain consistent whether tested in air or seawater.
Galvanic Corrosion
Among the galvanic series, titanium is positioned near the noble end, close to stainless steels, and usually acts as a cathode when coupled with other metals. Thus, titanium remains unaffected by galvanic corrosion and can actually accelerate the corrosion of other metals. Coupling titanium with more noble metals like graphite further enhances its passivity.
Fatigue Properties
Grade 2 Titanium Rod maintains its fatigue properties even in the presence of seawater. Its fatigue endurance limits and *** growth rates do not degrade whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable, provided necessary precautions are followed. Due to titanium's reactivity, an inert gas shield is required both on the OD and ID of the rod, which 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 necessary for Titanium Rod.
