AMS 4965 - Bars, Forgings (Solution treated and aged)
AMS 4967 - Bars, Forgings (Annealed, Heat Treatable)
HEAT TREATMENT
- For high hardness, tensile strength, and fatigue resistance, anneal at 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy offers versatile heat treatment options to meet various requirements. - 1. Anneal: Heat at 1,275 -1,400°F (691 - 760°C) for ½ to 2 hours, then cool in air or furnace.
- 2. Stress Relief Anneal: Heat at 1,000 -1,200°F (538 - 649°C) for 1 to 8 hours, then cool in air or furnace.
- 3. Solution Heat Treat: Heat at 1,675 -1,750°F (913 - 954°C) for 1 hour, followed by a water quench.
- 4. Aging: Heat at 975 -1,025°F (524 - 552°C) for 4 to 8 hours, then cool in air.
In the solution-treated and aged condition, rapid quenching of small sections provides optimal properties. Larger sections and/or delayed quenching may result in suboptimal properties.
HARDNESS
Typical hardness in the annealed condition ranges from Rockwell C 30-34, increasing to Rockwell C 35-39 in the solution and aged condition.
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 for achieving optimal properties.
- Ti-6Al-4V, Grade 5 alloy bar presents challenges when forming at room temperature, even in its annealed state. For severe operations like bending or stretching, annealed material can be handled at temperatures up to 1,200°F (649°C) without compromising its mechanical properties. Hot sizing or forming is achievable through creep forming within the range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar can be machined effectively by employing austenitic stainless steel machining techniques. This entails slow speeds, high feeds, rigid tools, and ample use of non-chlorinated cutting fluids for optimal results.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod exhibits excellent weldability in both the annealed and solution-aged conditions, with aging occurring during post-weld heat treatment. It is crucial to avoid 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 zones, supplemented by a tail shield. Spot, seam, and flash welding are also feasible without a protective atmosphere.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to hydrogen contamination from improper pickling and can also absorb oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such contamination can lead to reduced ductility, adversely impacting notch sensitivity and forming capabilities.

Grade 2 Titanium Rod: Unmatched Quality and Performance
Corrosion Resistance: Durability You Can Trust
Avoid strong reducing acids, fluoride solutions, pure oxygen, or anhydrous *** with titanium for optimal performance.
General Corrosion: Reliable Resistance
Grade 2 titanium's general corrosion rates in various environments are detailed in Table 1. CP titanium excels in resisting corrosion across diverse settings, including:
- Seawater and Brines for Marine Applications
- Inorganic Salts: Ensuring Longevity
- Moist *** Gas: Unyielding Performance
- Alkaline Solutions: Robust Resistance
- Oxidizing Acids: Superior Durability
- Organics and Organic Acids: Reliable Performance
- Sulfur Compounds: Enduring Tough Conditions
Crevice Corrosion: Superior Resistance
CP titanium stands out in salt solutions, offering resistance to crevice corrosion at temperatures below 80°C (176°F) regardless of pH, even under super chlorinated conditions.
Stress Corrosion Cracking: Exceptional Resilience
Grade 2 titanium excels in resisting stress corrosion cracking (SCC) in hot chloride solutions and remains immune to SCC in seawater.
Erosion Corrosion: Outstanding Durability
Titanium showcases excellent resistance to erosion in flowing environments.
Seawater with velocities up to 130 ft/sec (40 m/sec) shows negligible effect on the material. Even with abrasive particles like sand present, there's only a minor impact on corrosion resistance.
Hydrogen Embrittlement
Titanium exposed to seawater exhibits no significant hydrogen absorption, even at elevated temperatures. Hydrogen absorption typically occurs only when three specific conditions are met:
- 1. pH level 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 a unique resistance to all forms of microbiologically influenced corrosion. However, since they are non-toxic to marine organisms, biofouling can occur in seawater. This can be mitigated through chlorination or by increasing water velocity through heat exchangers.
Corrosion Fatigue
Titanium demonstrates no decrease in fatigue performance in the presence of seawater. Fatigue endurance limits and *** growth rates remain consistent whether in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is near the noble end, close to stainless steels, and typically acts as a cathode when paired with other metals. While titanium itself is not affected by galvanic corrosion, it can accelerate the corrosion of the other metal. Coupling it with more noble metals, such as graphite, further enhances titanium's passivity.
Fatigue Properties
Grade 2 Titanium Rod exhibits remarkable fatigue properties, showing no degradation when exposed to seawater. Fatigue endurance limits and *** growth rates are consistent whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod offers excellent weldability when proper precautions are observed. Due to titanium's reactivity, an inert gas shield must cover both the OD and ID of the rod. The material must also be free from any grease or oil contamination.
Typically, Grade 2 Titanium Rod is welded using manual or automatic TIG welding, with or without filler wire. Low heat input is recommended to minimize the heat-affected zone. Post-weld heat treatment is not commonly required for Titanium Rod.
