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
- When exceptional hardness, tensile strength, and fatigue resistance are required, annealing can be performed at 1,700-1,900°F (927 - 1,038°C).
The DAXUN 6-4™ Grade 5 alloy offers versatile heat treatment options. - 1. Anneal: Conducted at 1,275 - 1,400°F (691 - 760°C) for ½ to 2 hours, followed by air or furnace cooling.
- 2. Stress Relief Anneal: Performed at 1,000 - 1,200°F (538 - 649°C) for 1 to 8 hours, then air or furnace cooled.
- 3. Solution Heat Treat: Executed at 1,675 - 1,750°F (913 - 954°C) for 1 hour, followed by water quenching.
- 4. Aging: Conducted at 975 - 1,025°F (524 - 552°C) for 4 to 8 hours, then air cooled.
In the solution treated and aged state, rapid quenching of small sections delivers optimal properties, while larger sections or delayed quenching may result in suboptimal properties.
HARDNESS
Typical hardness in the annealed condition ranges from Rockwell C 30-34, while in the solution and aged condition, it ranges from Rockwell C 35-39.
Forgeability/Formability
- The 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.
- Ti-6Al-4V, Grade 5 alloy bar is notably challenging to form at room temperature, even in its annealed state. However, severe forming operations like bending or stretching can be performed on annealed material at elevated temperatures up to 1,200°F (649°C) without compromising its mechanical properties. For hot sizing or forming, creep forming within the range of 1,000 - 1,200°F (538 - 649°C) can be effectively employed.
Machinability
Ti-6Al-4V, Grade 5 alloy bar can be efficiently machined using austenitic stainless steel machining techniques, incorporating slow machining speeds, high feeds, and rigid tools, along with the generous use of non-chlorinated cutting fluids.
Weldability
Ti-6Al-4V, Grade 5 alloy rod offers excellent weldability, whether in the annealed condition or in the solution and partially aged state, with aging completed during post-weld heat treatment. It is crucial to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding should be done in an inert gas-filled chamber or using inert gas to weld the molten metal and the adjacent heated zones, with a tail shield. Spot, seam, and flash welding can be conducted without the need for a protective atmosphere.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to contamination by hydrogen from improper pickling and by oxygen, nitrogen, and carbon during forging, heat treating, and brazing. Such contamination can lead to a loss of ductility, adversely affecting notch sensitivity and forming characteristics.

Premium Grade 2 Titanium Rod
Exceptional Corrosion Resistance
Caution: Titanium should not be exposed to strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion Insights
Table 1 showcases the general corrosion rates for Grade 2 titanium in various environments. CP titanium boasts superior corrosion resistance across diverse conditions including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion Resistance
CP titanium shows remarkable resistance to crevice corrosion in salt solutions, outperforming stainless steels. It remains immune to crevice corrosion at temperatures below 80°C (176°F), even in highly chlorinated conditions.
Stress Corrosion Cracking Resistance
Grade 2 titanium displays outstanding resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion Resistance
Titanium excels in resisting erosion in flowing environments.
Our titanium materials exhibit remarkable resilience against seawater velocities reaching up to 130 ft/sec (40 m/sec), showing negligible impact on their integrity. Even with the presence of abrasive particles, such as sand, the material's corrosion resistance remains impressively uncompromised.
Understanding Hydrogen Embrittlement
Titanium's exposure to seawater does not lead to significant hydrogen absorption, even at elevated temperatures. Hydrogen absorption typically occurs only when these three specific conditions are met:
- 1. The pH level is below 3 or above 12,
- 2. The temperature exceeds 176°F (80°C),
- 3. A mechanism exists for hydrogen generation, such as a galvanic couple or impressed current.
Bio-Corrosion Resistance
Titanium alloys boast a unique immunity to all forms of microbiologically influenced corrosion. While titanium's non-toxicity to marine organisms can lead to biofouling in seawater, this can be effectively minimized through chlorination or by increasing the water velocity within the heat exchanger.
Unmatched Corrosion Fatigue Resistance
Unlike many other materials, titanium exhibits no reduction in fatigue performance when subjected to seawater. Its fatigue endurance limits and *** growth rates remain consistent whether tested in air or seawater.
Galvanic Corrosion Characteristics
In the galvanic series, titanium is positioned towards the noble end, close to stainless steels, and usually acts as a cathode when paired with other metals. While titanium remains unaffected by galvanic corrosion, it may accelerate the corrosion of the other metal. Coupling titanium with more noble metals, like graphite, further enhances its passivity.
Superior Fatigue Properties
Grade 2 Titanium Rods exhibit no degradation in fatigue properties when exposed to seawater. Their fatigue endurance limits and *** growth rates are maintained consistently, whether tested in air or under seawater conditions.
Exceptional Weldability
CP2 Grade Titanium Rods are highly weldable, provided the necessary precautions are taken. Due to titanium's reactivity, an inert gas shield must be applied on both the OD and ID of the rod, ensuring it is free from grease or oil contamination.
Typically, Grade 2 Titanium Rods are welded using manual or automatic TIG welding, with or without filler wire. Low heat input should be utilized to minimize the heat-affected zone. Post-weld heat treatment is generally not required for Titanium Rods.
