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, our annealing process operates at 1,700-1,900°F (927 - 1,038°C).
The 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
Rapid quenching of small sections in the solution treated and aged condition achieves optimal properties, whereas larger sections and delayed quenching may lead to suboptimal results.
HARDNESS
In the annealed condition, typical hardness ranges from Rockwell C 30-34, and Rockwell C 35-39 in the solution and aged condition.
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 35% reduction ensures the best properties.
- Ti-6Al-4V, Grade 5 alloy bar is notably challenging to form at room temperature, even when annealed. Consequently, severe forming processes such as bending or stretching can be undertaken on annealed material at temperatures up to 1,200°F (649°C) without compromising its mechanical properties. Additionally, hot sizing or forming is achievable through creep forming within the temperature range of 1,000 - 1,200°F (538 - 649°C).
Machinability
Ti-6Al-4V, Grade 5 alloy bar exhibits excellent machinability using austenitic stainless steel methods. For optimal results, utilize slow machining speeds, high feeds, robust tools, and copious amounts of non-chlorinated cutting fluids.
Weldability
Ti-6Al-4V, Grade 5 alloy rod is effortlessly weldable whether in the annealed state or in the solution and partially aged condition, with aging occurring during post-weld heat treatment. Measures should be taken to avoid contamination from oxygen, nitrogen, and hydrogen. Fusion welding can be performed in an inert gas-filled chamber or with inert gas shielding the molten metal and adjacent heated zones, accompanied by a tail shield. Additionally, spot, seam, and flash welding can be executed without the need for a protective atmosphere.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rod may be susceptible to hydrogen contamination from improper pickling, as well as oxygen, nitrogen, and carbon contamination during forging, heat treating, brazing, etc. Such contamination can lead to a reduction in ductility, adversely affecting 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
Table 1 illustrates the general corrosion rates for Grade 2 titanium across various media. CP titanium displays excellent corrosion resistance in numerous environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organic Compounds 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 experience crevice corrosion at temperatures below 80°C (176°F), even in highly chlorinated conditions, regardless of pH.
Stress Corrosion Cracking
Grade 2 titanium demonstrates exceptional resistance to stress corrosion cracking (SCC) in hot chloride solutions and remains immune to SCC in seawater.
Erosion Corrosion
Titanium exhibits remarkable resistance to erosion in dynamic environments, particularly in flowing
seawater with velocities reaching up to 130 ft/sec (40 m/sec), demonstrating negligible impact on the material. Even when abrasive particles like sand are present, the effect on corrosion remains minimal.
Hydrogen Embrittlement
Titanium does not significantly absorb hydrogen when exposed to seawater, even at elevated temperatures. Hydrogen absorption occurs under very specific conditions, which include:
- A pH level below 3 or above 12
- Temperature exceeding 176°F (80°C)
- Presence of a mechanism for hydrogen generation, such as a galvanic couple or impressed current.
Bio-corrosion
Titanium alloys show exceptional immunity to microbiologically influenced corrosion. Although titanium alloys are non-toxic to marine organisms, biofouling in seawater can occur. This can be mitigated by chlorination or increasing water velocity through heat exchangers.
Corrosion Fatigue
Unlike many other materials, titanium does not suffer reduced fatigue performance in seawater. Fatigue endurance limits and *** growth rates remain consistent whether tested in air or seawater.
Galvanic Corrosion
Positioned towards the noble end of the galvanic series, near stainless steels, titanium usually acts as the cathode when paired with other metals. As a result, titanium is generally unaffected by galvanic corrosion but may accelerate the corrosion of other metals. When coupled with more noble metals like graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rods retain their fatigue properties in the presence of seawater. Fatigue endurance limits and *** growth rates remain unchanged whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rods are highly weldable with proper precautions. Due to titanium's reactivity, inert gas shielding is essential on both the OD and ID of the rod. The material must be clean and free from 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 not usually required for Titanium Rods.
