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 applications requiring high hardness, tensile strength, and fatigue strength, annealing can be performed 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 small sections yields optimum properties. However, larger section sizes and/or delayed quenching may result in less than optimum properties.
HARDNESS
Typical hardness in the annealed condition is Rockwell C 30-34. In the solution and aged condition, it is approximately 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 of 35% reduction is recommended to achieve optimum properties.
- The Ti-6Al-4V, Grade 5 alloy bar, renowned for its exceptional strength, faces challenges in forming at room temperature, even when annealed. Severe forming operations such as bending or stretching can be effectively performed on annealed material at elevated temperatures up to 1,200°F (649°C) without compromising its mechanical properties. Additionally, hot sizing or forming can be achieved 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 exhibits excellent machinability when using austenitic stainless steel machining methods. It operates best with slow machining speeds, high feed rates, rigid tooling, and a generous application of non-chlorinated cutting fluids to ensure optimal performance and longevity.
Weldability
Remarkably weldable, the Ti-6Al-4V, Grade 5 alloy rod can be joined in either the annealed condition or the solution and partially aged condition. Aging is typically accomplished during post-weld heat treatment. Careful measures are necessary to avoid contamination from oxygen, nitrogen, and hydrogen. Fusion welding is best conducted within an inert gas-filled chamber or with inert gas shielding to protect the molten metal and adjacent heated zones. Additionally, spot, seam, and flash welding can be performed without a protective atmosphere.
Special Considerations
When handling the Ti-6Al-4V, Grade 5 titanium alloy rod, special attention is required to prevent 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 loss of ductility, negatively 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 presented in Table 1. CP titanium shows good corrosion resistance in numerous environments including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion
CP titanium exhibits excellent resistance to crevice corrosion in salt solutions compared to stainless steels. Under temperatures below 80°C (176°F), CP titanium does not exhibit crevice corrosion, even under super chlorinated conditions, regardless of pH.
Stress Corrosion Cracking
Grade 2 titanium shows outstanding resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion
Titanium shows superior resistance to erosion in flowing environments.
Our Pure Titanium Rod ASTM B348 Gr1 for Aerospace exhibits extraordinary performance even in challenging environments. It can withstand seawater velocities up to 130 ft/sec (40 m/sec) with negligible impact on its integrity. The presence of abrasive particles, like sand, has only a minimal effect on its corrosion resistance.
Hydrogen Embrittlement
Titanium's interaction with seawater, even at elevated temperatures, does not lead to significant hydrogen absorption. This phenomenon typically occurs only under specific conditions:
- The pH level is either below 3 or above 12
- The 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 a unique immunity to all forms of microbiologically influenced corrosion (MIC). While they are non-toxic to marine life, thus susceptible to biofouling, this can be effectively managed through chlorination or by increasing water flow through heat exchangers.
Corrosion Fatigue
Unlike many other materials, titanium maintains its fatigue performance in the presence of seawater. The fatigue endurance limits and *** growth rates remain consistent whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is positioned near the noble end alongside stainless steels. Consequently, it usually acts as the cathode when coupled with other metals, thus avoiding galvanic corrosion itself while potentially accelerating the corrosion of the coupled metal. When paired with more noble metals like graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod is exceptional in that it does not exhibit any degradation in fatigue properties even in seawater. Both the fatigue endurance limits and fatigue *** growth rates are consistent whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod boasts superb weldability, provided that appropriate precautions are observed. Due to titanium's reactivity, an inert gas shield must be applied to both the OD and ID of the rod, and the material 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 size, low heat input is recommended. Post-weld heat treatment is generally not required for Titanium Rod.
