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 resistance, annealing can be conducted 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.
Optimal properties are achieved through rapid quenching of small sections in the solution treated and aged condition. Larger sections and delayed quenching may lead to suboptimal properties.
HARDNESS
In the annealed condition, typical hardness is Rockwell C 30-34, and it ranges from 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 to achieve optimal properties.
- The Ti-6Al-4V, Grade 5 alloy bar, renowned for its high difficulty in forming at room temperature, showcases exceptional performance even in its annealed state. For severe forming operations such as bending or stretching, it can be effectively handled at elevated temperatures up to 1,200°F (649°C) without compromising its mechanical properties. Furthermore, hot sizing or forming can be adeptly achieved by utilizing creep forming techniques within the temperature range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar can be expertly machined using specialized austenitic stainless steel machining methods. These methods involve slow machining speeds, high feeds, rigid tools, and an abundant use of non-chlorinated cutting fluids, ensuring optimal machining efficiency and precision.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod features excellent weldability in both the annealed and solution or partially aged conditions. Aging post-weld heat treatment is recommended to achieve desired properties. It is crucial to prevent contamination by oxygen, nitrogen, and hydrogen. Fusion welding is best performed in an inert gas-filled environment or with inert gas shielding to protect the molten and adjacent heated zones. Spot, seam, and flash welding can be successfully conducted without protective atmospheres.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to contamination, particularly from hydrogen during improper pickling, and from oxygen, nitrogen, and carbon during forging, heat treating, or brazing. This contamination can lead to a reduction in ductility, adversely affecting notch sensitivity and forming characteristics. Proper handling is essential to maintain the integrity of the alloy rod.

Grade 2 Titanium Rod
Corrosion Resistance
Usage Precautions - Avoid usage with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous *** to maintain titanium's integrity.
General Corrosion
Corrosion Rates - The general corrosion rates for Grade 2 titanium across various media are detailed in Table 1. Grade 2 CP titanium offers excellent corrosion resistance in diverse environments such as:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion
Crevice Corrosion Resistance - Grade 2 CP titanium exhibits robust resistance to crevice corrosion in salt solutions, outperforming stainless steels. It remains unaffected at temperatures below 80°C (176°F), even under highly chlorinated conditions.
Stress Corrosion Cracking
SCC Resistance - Grade 2 titanium resists stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater environments.
Erosion Corrosion
Erosion Resistance - Titanium demonstrates outstanding resistance to erosion in flowing environments, ensuring long-lasting performance.
Seawater with velocities up to 130 ft/sec (40 m/sec) exhibits negligible impact on the material integrity. Even when abrasive particles, such as sand, are present, the corrosion effects remain minimal.
Hydrogen Embrittlement
Titanium displays no significant absorption of hydrogen when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only under the following conditions:
- The pH level is either below 3 or above 12.
- Temperature exceeds 176°F (80°C).
- A mechanism for hydrogen generation exists, such as a galvanic couple or an impressed current.
Bio-Corrosion
Titanium alloys exhibit a unique immunity to all forms of microbiologically influenced corrosion. These alloys do not show toxicity toward marine organisms, which can lead to biofouling in seawater. This can be managed by chlorination or increasing water velocity through the heat exchanger.
Corrosion Fatigue
Unlike many materials, titanium does not experience a decline in fatigue performance in seawater. Fatigue endurance limits and fatigue *** growth rates are consistent, whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is near the noble end, close to stainless steels, and usually acts as the cathode when paired with other metals. Titanium remains unaffected by galvanic corrosion but can accelerate the corrosion of the paired metal. Coupling titanium with more noble metals, such as graphite, enhances titanium's passivity.
Fatigue Properties
Grade 2 Titanium Rod retains its fatigue properties in seawater, unlike many other materials. Fatigue endurance limits and fatigue *** growth rates remain unchanged whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable, provided the necessary precautions are taken. Given titanium's reactivity, an inert gas shield must cover both the OD and ID of the rod. The material must also be free of grease or oil contamination.
Grade 2 Titanium Rods are typically welded using manual or automatic TIG welding, with or without filler wire. Low heat input is recommended to minimize the heat-affected zone size. Post-weld heat treatment is generally not required.
