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 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 to meet your specific needs. - 1. Anneal: Heat to 1,275 -1,400°F (691 - 760°C) for ½ to 2 hours, then air or furnace cool.
- 2. Stress Relief Anneal: Heat to 1,000 -1,200°F (538 - 649°C) for 1 to 8 hours, then air or furnace cool.
- 3. Solution Heat Treat: Heat to 1,675 -1,750°F (913 - 954°C) for 1 hour, then water quench.
- 4. Aging: Heat to 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 achieves optimal properties, whereas larger sections or delayed quenching may result in less optimal properties.
HARDNESS
The typical hardness of our annealed titanium bars is Rockwell C 30-34, while the solution and aged condition yields a hardness of Rockwell C 35-39.
Forgeability/Formability
- 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 35% reduction is recommended for achieving optimal properties.
- The Ti-6Al-4V, Grade 5 alloy bar is known for its challenging formability at room temperature, even when annealed. However, severe forming operations such as bending or stretching can be effectively performed on the annealed material at elevated temperatures up to 1,200°F (649°C) without compromising its mechanical properties. Hot sizing or forming can be successfully achieved through creep forming within a temperature range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar can be precisely machined using methods similar to those for austenitic stainless steel. This requires slow machining speeds, high feed rates, rigid tools, and the use of generous amounts of non-chlorinated cutting fluids to ensure optimal machining performance.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod demonstrates excellent weldability in the annealed state or in the solution and partially aged condition, with aging typically occurring during post-weld heat treatment. To prevent contamination from oxygen, nitrogen, and hydrogen, precautions must be taken. Fusion welding can be conducted in an inert gas-filled chamber or using inert gas to shield the molten metal and adjacent heated areas with a tail shield. Additionally, spot, seam, and flash welding can be executed without the need for a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to contamination by hydrogen from improper pickling, as well as by oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such contamination can lead to a reduction in ductility, negatively impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion Resistance
Titanium should not be exposed to strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion
Grade 2 titanium demonstrates excellent general corrosion resistance across various media, as indicated in Table 1. CP titanium resists corrosion in numerous environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion
Compared to stainless steels, CP titanium offers superior resistance to crevice corrosion in salt solutions. It remains unaffected at temperatures below 80°C (176°F), even in highly chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium exhibits outstanding resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion
Titanium showcases exceptional erosion resistance in flowing environments.
Seawater with velocities up to 130 ft/sec (40 m/sec) exhibits negligible impact on the material's integrity. The presence of abrasive particles, such as sand, minimally affects corrosion, ensuring robust performance in marine environments.
Hydrogen Embrittlement
Titanium shows no significant hydrogen absorption even when exposed to seawater at elevated temperatures. Hydrogen absorption typically occurs only if all three of the following conditions are met:
- The pH level is < 3 or > 12
- Temperature exceeds 176°F (80°C)
- A mechanism for hydrogen generation is present, such as a galvanic couple or impressed current.
Biocorrosion
Titanium alloys exhibit exceptional immunity to all forms of microbiologically influenced corrosion. Despite a lack of toxicity toward marine organisms that may cause biofouling in seawater, this can be mitigated by chlorination or by increasing water velocity through heat exchangers.
Corrosion Fatigue
Titanium maintains its fatigue performance in seawater, unlike many other materials. Its fatigue endurance limits and *** growth rates remain consistent whether tested in air or seawater, ensuring reliable durability.
Galvanic Corrosion
In the galvanic series, titanium resides near the noble end, close to stainless steels, and typically acts as the cathode when coupled with other metals. As such, titanium is resistant to galvanic corrosion and can accelerate the corrosion of the other metal. Coupling with more noble metals, like graphite, further enhances titanium's passivity.
Fatigue Properties
Grade 2 Titanium Rod showcases no degradation in fatigue properties when exposed to seawater. Both fatigue endurance limits and *** growth rates remain consistent whether tested in air or seawater, ensuring steadfast strength.
Weldability
CP2 Grade Titanium Rod offers excellent weldability with proper precautions. Due to titanium's reactivity, an inert gas shield must be used on both the OD and ID of the rod, and the material must be free of any grease or oil contamination.
Grade 2 Titanium Rod is commonly welded using manual or automatic TIG welding, with or without filler wire. Low heat input is recommended to minimize the heat affected zone. Post-weld heat treatment is typically unnecessary.
