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 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 optimum properties, while larger sections or delayed quenching may result in suboptimal properties.
Hardness
Typical hardness in the annealed state is Rockwell C 30-34, and approximately Rockwell C 35-39 when solution treated and aged.
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 of 35% reduction is recommended for achieving optimal properties.
- The Ti-6Al-4V, Grade 5 alloy bar is notably challenging to form at room temperature, even when in an annealed state. Consequently, severe forming operations such as bending or stretching are best performed on annealed material at temperatures up to 1,200°F (649°C) to preserve mechanical properties. Hot sizing and forming can be executed 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 austenitic stainless steel methods. This involves slow machining speeds, high feeds, rigid tools, and the generous application of non-chlorinated cutting fluids to ensure precision and quality.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is easily weldable in both the annealed and solution and partially aged conditions, with aging achieved during post-weld heat treatment. To maintain integrity, it is crucial to prevent contamination with oxygen, nitrogen, and hydrogen. Fusion welding should be performed in an inert gas-filled chamber or with inert gas shielding for the molten metal and adjacent heated zones, utilizing a tail shield. Additionally, spot, seam, and flash welding can be performed without needing a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod can suffer hydrogen contamination from improper pickling and oxygen, nitrogen, and carbon contamination during forging, heat treating, and brazing processes. Such contamination may lead to a reduction in ductility, adversely affecting notch sensitivity and forming properties.

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 a variety of media are shown in Table 1. CP titanium exhibits good corrosion resistance to a wide variety of environments including:
- Seawater and brines
- Inorganic salts
- Moist *** gas
- Alkaline solutions
- Oxidizing acids
- Organics and organic acids
- Sulfur compounds
Crevice corrosion
CP titanium exhibits good resistance to crevice corrosion in salt solutions compared to stainless steels. CP titanium will not exhibit crevice corrosion at temperatures under 80 °C ( 176°F) regardless of pH, even under super chlorinated conditions.
Stress corrosion cracking
Grade 2 titanium shows excellent resistance to stress corrosion (SCC) cracking in hot chloride solutions and is immune to sec in seawater.
Erosion corrosion
Titanium shows excellent resistance to erosion in flowing
Seawater with velocities up to 130 ft/sec (40 m/sec) shows negligible effects on this resilient material. Even the presence of abrasive particles, such as sand, has minimal impact on its corrosion resistance.
Hydrogen Embrittlement
There is no significant absorption of hydrogen into titanium, even when exposed to seawater at elevated temperatures. Hydrogen absorption occurs only if the following three stringent conditions are simultaneously met:
- The pH level is either < 3 or > 12
- Temperature exceeds 176°F (80°C)
- A mechanism like a galvanic couple or impressed current exists for hydrogen generation.
Bio-Corrosion
Titanium alloys exhibit remarkable immunity to all forms of microbiologically influenced corrosion. Despite not displaying toxicity toward marine organisms, biofouling in seawater can occur. This can be effectively minimized through chlorination or increased water velocity through the heat exchanger.
Corrosion Fatigue
Unlike many other materials, titanium does not experience a decrease in fatigue performance in seawater. Both the fatigue endurance limits and fatigue *** growth rates remain consistent whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is positioned toward the noble end, near stainless steels, typically acting as the cathode when coupled with other metals. Consequently, titanium is not affected by galvanic corrosion but can accelerate the corrosion of the other metal. Coupling titanium with more noble metals, such as graphite, enhances titanium's passivity further.
Fatigue Properties
Grade 2 Titanium Rod does not exhibit degradation in fatigue properties when exposed to seawater. Fatigue endurance limits and fatigue *** growth rates are consistent whether in air or seawater.
Weldability
CP2 Grade Titanium Rod boasts excellent weldability, provided essential precautions are taken. Due to titanium's reactivity, an inert gas shield must be applied to both the OD and ID of the rod. It's crucial the material is free from any grease or oil contamination.
Grade 2 Titanium Rod is typically welded using manual or automatic TIG welding, with or without filler wire. Employing low heat input is advisable to minimize the heat affected zone size. Post-weld heat treatment is generally unnecessary for Titanium Rod.
