Specifications for Titanium Bars
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 Guidelines
- To achieve high hardness, tensile strength, and fatigue strength, annealing can be conducted at temperatures of 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy offers versatile heat treatment options. - 1. Anneal: Perform at 1,275 -1,400°F (691 - 760°C) for ½ to 2 hours, followed by air or furnace cooling.
- 2. Stress Relief Anneal: Conduct at 1,000 -1,200°F (538 - 649°C) for 1 to 8 hours, then air or furnace cool.
- 3. Solution Heat Treat: Apply at 1,675 -1,750°F (913 - 954°C) for 1 hour, followed by water quenching.
- 4. Aging: Age at 975 -1,025°F (524 - 552°C) for 4 to 8 hours, then air cool.
In the solution-treated and aged condition, rapid quenching of smaller sections yields optimal properties, while larger sections or delayed quenching may result in less optimal properties.
Material Hardness
Typical hardness values are Rockwell C 30-34 in the annealed condition and Rockwell C 35-39 in the solution-treated and aged condition.
Exceptional Forgeability/Formability
- Our Ti-6Al-4V, Grade 5 alloy bar is forged at a temperature of 1,750°F (954°C) with a final forging temperature of 1,450°F (788°C). A minimum of 35% reduction is recommended to achieve optimal properties.
- The Ti-6Al-4V, Grade 5 alloy bar is known for its challenging formability at room temperature, even in an annealed state. For severe forming operations like bending or stretching, annealed materials can be handled at temperatures up to 1,200°F (649°C) without compromising mechanical properties. Hot sizing or forming is achievable through creep forming within the 1,000 - 1,200°F (538 - 649°C) range.
Machinability
The Ti-6Al-4V, Grade 5 alloy bar can be efficiently machined using methods suitable for austenitic stainless steel. This requires slow machining speeds, high feed rates, rigid tooling, and the liberal application of non-chlorinated cutting fluids.
Weldability
In the annealed condition or the solution and partially aged condition, the Ti-6Al-4V, Grade 5 alloy rod exhibits excellent weldability, with post-weld heat treatment completing the aging process. To prevent contamination by oxygen, nitrogen, and hydrogen, welding operations should be conducted in an inert gas-filled chamber or using inert gas to shield the molten metal and adjacent heated zones, along with a tail shield. Spot, seam, and flash welding can proceed without a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to contamination from hydrogen during improper pickling and from oxygen, nitrogen, and carbon during forging, heat treating, and brazing. Such contamination can lead to decreased ductility, negatively impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion Resistance
Titanium should not be used with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion
General corrosion rates for Grade 2 titanium in various media are shown in Table 1. Commercially Pure (CP) titanium demonstrates excellent corrosion resistance in 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 offers superior resistance to crevice corrosion in salt solutions compared to stainless steels. It does not exhibit crevice corrosion at temperatures below 80°C (176°F) irrespective of pH, even under highly chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium shows exceptional resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion
Titanium displays excellent resistance to erosion in flowing media.
Our high-performance titanium alloys show negligible effects when exposed to seawater velocities up to 130 ft/sec (40 m/sec). Even the presence of abrasive particles, such as sand, has only a minimal impact on its corrosion resistance, solidifying its reliability in extreme marine conditions.
Understanding Hydrogen Embrittlement
Titanium exhibits remarkable resistance to hydrogen embrittlement even when exposed to seawater at elevated temperatures. Hydrogen absorption in titanium is typically insignificant unless all three of the following critical conditions are met:
- 1. The pH level is either below 3 or above 12.
- 2. The temperature exceeds 176°F (80°C).
- 3. A mechanism for hydrogen generation exists, such as a galvanic couple or impressed current.
Bio-corrosion: An In-depth Look
Titanium alloys boast an unparalleled immunity to all forms of microbiologically influenced corrosion. While these alloys are non-toxic to marine life, biofouling can occur in seawater environments. This can be effectively minimized through chlorination or by increasing the water velocity through heat exchangers.
Exploring Corrosion Fatigue
Titanium's endurance is unmatched; it does not exhibit decreased fatigue performance in seawater environments. Whether tested in air or seawater, its fatigue endurance limits and *** growth rates remain the same, ensuring long-lasting reliability.
Galvanic Corrosion Insights
In the galvanic series, titanium is positioned near the noble end alongside stainless steels, typically acting as the cathode when paired with other metals. This means titanium remains unaffected by galvanic corrosion and can even accelerate the corrosion of the other metal. Coupling titanium with more noble metals like graphite further enhances its passivity.
Fatigue Properties Unveiled
Grade 2 Titanium Rod stands out by not showing any degradation in fatigue properties when exposed to seawater. Fatigue endurance limits and *** growth rates remain consistent, whether the material is tested in air or seawater.
Expert Weldability of Titanium Rods
CP2 Grade Titanium Rod demonstrates excellent weldability, provided essential precautions are taken. Due to titanium's reactivity, an inert gas shield must be applied to both the OD and ID of the rod. Additionally, the material must be free from grease or oil contamination.
Grade 2 Titanium Rod is typically welded using manual or automatic TIG welding, with or without filler wire. Employing low heat input minimizes the heat-affected zone. Generally, post-weld heat treatment is not required for Titanium Rod.
