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 strength, annealing is performed 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
In the solution treated and aged condition, rapid quenching of small sections yields optimal properties. Larger sections or delayed quenching may result in suboptimal properties.
HARDNESS
Typical hardness in the annealed condition ranges from Rockwell C 30-34, and in the solution and aged condition, it is approximately Rockwell C 35-39.
Forgeability/Formability
- Our Ti-6Al-4V, Grade 5 alloy bars are 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 presents a formidable challenge when forming at room temperature, even in its annealed state. However, this resilient material can undergo intense forming operations like bending or stretching at elevated temperatures up to 1,200°F (649°C) without compromising its mechanical integrity. 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 using austenitic stainless steel methods. This requires slow machining speeds, high feeds, rigid tooling, and copious amounts of non-chlorinated cutting fluids to ensure precision and product quality.
Weldability
In the annealed or partially aged condition, the Ti-6Al-4V, Grade 5 alloy rod is highly weldable, with further aging achieved during post-weld heat treatment. To maintain its integrity, it must be protected from contamination by oxygen, nitrogen, and hydrogen. Welding should occur in an inert gas chamber or with inert gas shielding the molten metal and adjacent heated zones, often employing a tail shield. Techniques like spot, seam, and flash welding do not require a protective atmosphere.
Special Considerations
Care must be taken with the Ti-6Al-4V, Grade 5 titanium alloy rod to avoid contamination from hydrogen during pickling and from oxygen, nitrogen, and carbon during processes like forging and heat treating. Such contamination can lead to a decrease in 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
The general corrosion rates for Grade 2 titanium in various media are shown in Table 1. Commercially Pure (CP) titanium exhibits excellent corrosion 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 exhibits good resistance to crevice corrosion in salt solutions compared to stainless steels. CP titanium does not exhibit crevice corrosion at temperatures under 80 °C (176°F), regardless of pH, even under super-chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium shows excellent resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion
Titanium shows excellent resistance to erosion in flowing environments.
Experience the durability of our Gr1 Titanium Rod ASTM B348 Aerospace High Purity Titanium Bar Supplier Grade1, capable of withstanding seawater velocities of up to 130 ft/sec (40 m/sec) with negligible effect. Even abrasive particles such as sand have minimal impact on its corrosion resistance.
Hydrogen Embrittlement
Remarkably, Gr1 Titanium Rod ASTM B348 exhibits no significant hydrogen absorption when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only under the following conditions:
- pH levels are < 3 or > 12
- Temperatures exceed 176°F (80°C)
- Presence of a hydrogen-generating mechanism, such as a galvanic couple or impressed current.
Bio-Corrosion
Our titanium alloys, including Gr1 Titanium Rod ASTM B348, demonstrate exceptional immunity to microbiologically influenced corrosion. While biofouling can occur due to the non-toxicity of titanium towards marine organisms, this can be mitigated by chlorination or increasing water velocity through the heat exchanger.
Corrosion Fatigue
Gr1 Titanium Rod ASTM B348 stands out with its consistent fatigue performance, unaffected by the presence of seawater. Its fatigue endurance limits and *** growth rates remain stable whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium, including Gr1 Titanium Rod ASTM B348, is positioned near the noble end, close to stainless steels. It typically acts as a cathode when paired with other metals, thereby resisting galvanic corrosion while potentially accelerating the corrosion of the other metal. Coupling with noble metals like graphite further enhances titanium's passivity.
Fatigue Properties
Grade 2 Titanium Rod, similar to our Gr1 Titanium Rod ASTM B348, maintains impeccable fatigue properties even in seawater. Fatigue endurance limits and *** growth rates remain consistent whether tested in air or seawater.
Weldability
Our CP2 Grade Titanium Rod is highly weldable, provided the necessary precautions are taken. Due to titanium's reactivity, an inert gas shield must cover both the OD and ID of the rod, and the material must be free from grease or oil contamination.
Typically, Grade 2 Titanium Rod, akin to Gr1 Titanium Rod ASTM B348, is welded using manual or automatic TIG welding, with or without filler wire. To minimize the heat-affected zone, low heat input is recommended. Post-weld heat treatment is generally not required.
