SPECIFICATIONS
AMS 4928 - Premium Bars, Forgings, and Forging Stock (Annealed)
AMS 4965 - Advanced Bars, Forgings (Solution Treated and Aged)
AMS 4967 - High-Grade Bars, Forgings (Annealed, Heat Treatable)
HEAT TREATMENT
- For applications requiring high hardness, tensile strength, and fatigue strength, an annealing process at 1,700-1,900°F (927 - 1,038°C) is recommended.
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
Optimal properties are achieved via rapid quenching of small sections in the solution treated and aged condition. Larger sections or delayed quenching may yield less optimal properties.
HARDNESS
Typical hardness ranges: Rockwell C 30-34 in the annealed condition, and Rockwell C 35-39 in the solution treated and aged condition.
Forgeability/Formability
- Ti-6Al-4V, Grade 5 alloy bar is forged at an ideal temperature of 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 is known for its formidable strength and resilience, making it particularly challenging to form at room temperature, even when annealed. For intense forming operations like bending or stretching, these tasks can be executed on annealed material at elevated temperatures reaching up to 1,200°F (649°C) without compromising its mechanical properties. In addition, hot sizing or forming can be efficiently conducted through creep forming within the temperature bracket of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar boasts excellent machinability, employing austenitic stainless steel machining techniques. This involves slower machining speeds, higher feed rates, robust tooling, and the generous application of non-chlorinated cutting fluids to ensure precision and efficiency.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is highly weldable, whether in its annealed state or in the solution-treated and partially aged condition, with aging occurring during post-weld heat treatment. Careful measures must be taken to avoid contamination from oxygen, nitrogen, and hydrogen. Fusion welding can be performed in an inert gas chamber or with inert gas shielding the weld pool and adjacent heated zones, complemented by a tail shield. Additionally, spot welding, seam welding, and flash welding are achievable without the need for a protective atmosphere.
Special Considerations
When working with the Ti-6Al-4V, Grade 5 titanium alloy rod, it is essential to avoid contamination with hydrogen from improper pickling, as well as with oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such contamination can lead to a reduction in ductility, adversely impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion Resistance
Avoidance Conditions - Titanium should not be exposed to strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion
Versatile Resistance - Grade 2 titanium demonstrates exceptional general corrosion resistance across various media, detailed in Table 1. CP titanium is resilient in environments including:
- Seawater and Brines - Ensuring durability and longevity in marine conditions.
- Inorganic Salts - Effective against a range of inorganic salts.
- Moist *** Gas - Resistant to corrosion in moist *** gas environments.
- Alkaline Solutions - Maintains integrity when exposed to alkaline solutions.
- Oxidizing Acids - Performs well in the presence of oxidizing acids.
- Organics and Organic Acids - Robust against organic and organic acid exposure.
- Sulfur Compounds - Resilient in sulfurous conditions.
Crevice Corrosion
Superior Crevice Corrosion Resistance - CP titanium excels in resisting crevice corrosion in salt solutions, outperforming stainless steel. It remains unaffected at temperatures below 80°C (176°F) regardless of pH, even in super chlorinated conditions.
Stress Corrosion Cracking
Outstanding SCC Resistance - Grade 2 titanium is highly resistant to stress corrosion cracking in hot chloride solutions, remaining immune in seawater conditions.
Erosion Corrosion
Erosion Resistance - Titanium showcases superior erosion resistance in flowing environments, ensuring sustained performance.
When subjected to seawater with velocities reaching up to 130 ft/sec (40 m/sec), titanium alloys exhibit negligible degradation. Even the presence of abrasive particles like sand barely impacts the material's outstanding corrosion resistance.
Hydrogen Embrittlement
Titanium demonstrates remarkable resistance to hydrogen absorption even when immersed in seawater at elevated temperatures. Hydrogen absorption is contingent upon the presence of three specific conditions:
- The pH level is below 3 or above 12
- The temperature exceeds 176°F (80°C)
- A mechanism exists that facilitates hydrogen generation, such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys exhibit extraordinary immunity to microbiologically influenced corrosion. Despite not being toxic to marine life, biofouling can occur in seawater. This can be effectively managed through chlorination or by increasing water velocity through the heat exchanger.
Corrosion Fatigue
Titanium stands out for maintaining its fatigue performance in the presence of seawater, unlike many other materials. Both fatigue endurance limits and fatigue *** growth rates remain consistent whether tested in air or seawater.
Galvanic Corrosion
Positioned near the noble end in the galvanic series, titanium often acts as a cathode when coupled with other metals, which means it is generally unaffected by galvanic corrosion. However, it can accelerate the corrosion of the other metal. Coupling titanium with more noble metals like graphite further enhances its passivity.
Fatigue Properties
Grade 2 Titanium Rod is notable for its stable fatigue properties even in seawater conditions. Fatigue endurance limits and fatigue *** growth rates remain consistent whether in air or seawater.
Weldability
CP2 Grade Titanium Rod offers excellent weldability provided specific precautions are observed. Due to titanium's reactivity, an inert gas shield must cover both the outer and inner surfaces. The material must also be clean of grease or oil contaminants.
Typically, Grade 2 Titanium Rods are welded using manual or automatic TIG welding techniques, with or without filler wire. Low heat input is advised to minimize the heat-affected zone. Post-weld heat treatment is generally unnecessary.
