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 conducted at 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy can be heat treated through various methods. - 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. Larger section sizes or delayed quenching may result in less than optimum properties.
HARDNESS
Typical hardness in the annealed condition is Rockwell C 30-34, while in the solution and aged condition, it ranges from 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 optimum properties.
- The Ti-6Al-4V, Grade 5 alloy bar, known for its resilience, presents challenges in forming at room temperature, even when annealed. However, it can undergo severe bending or stretching at elevated temperatures of up to 1,200°F (649°C) without compromising its mechanical integrity. For hot sizing or forming, the alloy performs exceptionally well through creep forming within the 1,000 - 1,200°F (538 - 649°C) range.
Machinability
The Ti-6Al-4V, Grade 5 alloy bar offers excellent machinability when processed using techniques akin to austenitic stainless steel. Employing slow machining speeds, high feeds, and rigid tools, along with liberal use of non-chlorinated cutting fluids, ensures optimal results.
Weldability
Our Ti-6Al-4V, Grade 5 alloy rod boasts superior weldability, whether in annealed, solution-treated, or partially aged conditions. Post-weld heat treatment facilitates aging. It is crucial to prevent contamination with oxygen, nitrogen, and hydrogen. Fusion welding is best achieved in an inert gas-filled chamber or with inert gas shielding. Additionally, spot, seam, and flash welding can be performed effectively without protective atmospheres.
Special Considerations
It's important to note that Ti-6Al-4V, Grade 5 titanium alloy rods can suffer hydrogen contamination from improper pickling, and oxygen, nitrogen, and carbon contamination during various processes. Such contamination may reduce ductility, adversely affecting notch sensitivity and forming properties.

Grade 2 Titanium Rod: Superior quality and reliability in every rod.
Corrosion Resistance: Best practices to ensure titanium's longevity and performance.
Avoid using titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous *** for optimal performance.
General Corrosion: Comprehensive insights into titanium's corrosion resistance.
Grade 2 titanium demonstrates excellent corrosion resistance across various media, as detailed in Table 1. CP titanium excels in environments including:
- Seawater and Brines: Exceptional resistance in marine environments.
- Inorganic Salts: Robust performance against inorganic salts.
- Moist *** Gas: Reliable resistance in ***-rich environments.
- Alkaline Solutions: Superior resistance to alkaline solutions.
- Oxidizing Acids: Strong performance against oxidizing acids.
- Organics and Organic Acids: Effective resistance to organic and organic acid environments.
- Sulfur Compounds: Excellent resistance to sulfur compounds.
Crevice Corrosion: Outstanding resistance in crevice-prone environments.
CP titanium exhibits superior crevice corrosion resistance in salt solutions compared to stainless steels, remaining unaffected at temperatures below 80°C (176°F).
Stress Corrosion Cracking: Exceptional resistance in challenging conditions.
Grade 2 titanium offers excellent resistance to stress corrosion cracking (SCC) in hot chloride solutions and remains immune to SCC in seawater.
Erosion Corrosion: Exceptional resistance to erosion in dynamic environments.
Titanium shows remarkable resistance to erosion in flowing media, ensuring durability and longevity.
Even in seawater with velocities soaring up to 130 ft/sec (40 m/sec), our material exhibits negligible impact. The presence of abrasive particles like sand produces only a minor effect on corrosion.
Hydrogen Embrittlement
Titanium shows no significant hydrogen absorption when exposed to seawater, regardless of higher temperatures. Hydrogen absorption typically occurs only under the following conditions:
- 1. pH levels are below 3 or exceed 12
- 2. The temperature rises above 176°F (80°C)
- 3. A mechanism exists for hydrogen generation, such as a galvanic couple or an impressed current.
Bio-Corrosion
Titanium alloys boast a unique immunity to all forms of microbiologically influenced corrosion. Although these alloys do not show toxicity toward marine organisms, biofouling can still occur in seawater. Mitigation methods include chlorination or increasing water velocity through the heat exchanger.
Corrosion Fatigue
Unlike many other materials, Titanium maintains its fatigue performance in seawater. Both fatigue endurance limits and *** growth rates are unaffected whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is positioned towards the noble end near stainless steels, typically acting as the cathode when coupled with other metals. Thus, titanium remains unaffected by galvanic corrosion but can accelerate the corrosion of the other metal. Coupling titanium with more noble metals, like graphite, enhances titanium's passivity.
Fatigue Properties
Grade 2 Titanium Rod is exceptional in that it does not suffer from degradation in fatigue properties even in seawater. Both fatigue endurance limits and *** growth rates are consistent whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable with the right precautions. Given titanium's reactivity, an inert gas shield is necessary on both the OD and ID of the rod. The material must be free of any grease or oil contamination.
Typically welded using manual or automatic TIG welding with or without filler wire, Grade 2 Titanium Rod requires low heat input to minimize the heat affected zone. Post weld heat treatment is generally not applied.
