AMS 4965 - Bars, Forgings (Solution treated and aged)
AMS 4967 - Bars, Forgings (Annealed, Heat Treatable)
HEAT TREATMENT
- When superior hardness, tensile strength, and fatigue strength are required, annealing can be conducted at 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy allows for versatile heat treatment 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 smaller sections yields optimal properties. Larger sections and/or delayed quenching may result in suboptimal properties.
HARDNESS
Typical hardness in the annealed condition is Rockwell C 30-34, while the solution and aged condition achieves 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 optimal properties.
- The Ti-6Al-4V, Grade 5 alloy bar, well-regarded for its robustness, poses challenges in forming at room temperature, even post-annealing. However, severe forming processes like bending or stretching can be effectively managed on annealed material at elevated temperatures, reaching up to 1,200°F (649°C), without compromising its mechanical integrity. For hot sizing or forming, creep forming within the range of 1,000 - 1,200°F (538 - 649°C) offers optimal results.
Machinability
Ti-6Al-4V, Grade 5 alloy bar exhibits excellent machinability when employing austenitic stainless steel techniques. Optimal machining is achieved at slow speeds, using high feeds, rigid tools, and copious amounts of non-chlorinated cutting fluids to ensure precision and efficiency.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod demonstrates outstanding weldability in both annealed and solution-aged states, with age hardening facilitated through post weld heat treatments. To maintain purity and structural integrity, welding must be performed in an inert gas environment to avoid contamination by oxygen, nitrogen, and hydrogen. Fusion welding is best done in an inert gas chamber or using inert gas shields for the molten metal and adjacent zones. Additionally, spot, seam, and flash welding are viable without protective atmospheres.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to contamination by hydrogen during improper pickling, and by oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such contamination could detract from ductility and adversely affect notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion Resistance
Note: Avoid using titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous *** to prevent adverse reactions.
General Corrosion
The corrosion rates for Grade 2 titanium across various media are detailed in Table 1. CP titanium showcases excellent resistance to a wide range of environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion
CP Titanium demonstrates superior resistance to crevice corrosion in salt solutions compared to stainless steels. It remains unaffected by crevice corrosion at temperatures below 80°C (176°F), even in highly chlorinated conditions.
Stress Corrosion Cracking
Grade 2 Titanium provides excellent protection against stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion
Titanium offers outstanding resistance to erosion in flowing environments, making it an ideal choice for various applications.
Seawater with velocities up to 130 ft/sec (40 m/sec) shows negligible effect on our material, maintaining its integrity. Even the presence of abrasive particles, such as sand, only slightly impacts the corrosion resistance.
Hydrogen Embrittlement
Remarkably, there is no significant absorption of hydrogen into titanium exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only when all three of the following conditions are met:
- 1. The pH level is below 3 or above 12
- 2. The temperature exceeds 176°F (80°C)
- 3. There exists a mechanism for hydrogen generation, such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys exhibit unique immunity to all forms of microbiologically influenced corrosion. However, due to their non-toxicity toward marine organisms, biofouling in seawater is possible. This can be effectively minimized through chlorination or by increasing the water velocity in the heat exchanger.
Corrosion Fatigue
Unlike many other materials, titanium does not suffer a decrease in fatigue performance in the presence of seawater. 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, and generally acts as the cathode when coupled with other metals. Hence, titanium is not affected by galvanic corrosion but can accelerate the corrosion of the other metal. When paired with more noble metals like graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod uniquely maintains its fatigue properties even in seawater conditions. Fatigue endurance limits and fatigue *** growth rates are identical, regardless of whether the rod is tested in air or seawater.
Weldability
CP2 Grade Titanium Rod boasts excellent weldability, provided that necessary precautions are observed. Given titanium's reactivity, an inert gas shield must cover both the OD and ID of the rod, and the material must be free of grease or oil contamination.
Typically, Grade 2 Titanium Rod is welded using manual or automatic TIG welding, with or without filler wire. It is recommended to use low heat input to minimize the heat-affected zone. Post weld heat treatment is not commonly performed on Titanium Rod.
