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
- To achieve high hardness, tensile strength, and fatigue strength, annealing is conducted 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 smaller sections yields optimal properties. Larger section sizes or delayed quenching may result in less than optimal properties.
HARDNESS
Typical hardness in the annealed condition is Rockwell C 30-34, and approximately Rockwell C 35-39 in the solution treated and aged condition.
Forgeability/Formability
- 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 of 35% reduction is recommended for optimal properties.
- The Ti-6Al-4V, Grade 5 alloy bar presents challenges in room temperature forming even when annealed. Hence, intensive operations like bending or stretching are best performed on annealed material at elevated temperatures of up to 1,200°F (649°C), ensuring mechanical properties remain unaffected. Hot sizing or forming can be adeptly executed via creep forming within the 1,000 - 1,200°F (538 - 649°C) range, maintaining the alloy's structural integrity.
Machinability
Ti-6Al-4V, Grade 5 alloy bar is compatible with austenitic stainless steel machining methods. Optimal results are achieved with slow machining speeds, high feed rates, sturdy tools, and generous use of non-chlorinated cutting fluids to ensure precision and prevent material degradation.
Weldability
Easily weldable in both the annealed and solution-aged conditions, the Ti-6Al-4V, Grade 5 alloy rod requires strict precautions to avoid contamination from oxygen, nitrogen, and hydrogen. Fusion welding should be performed in an inert gas environment to protect the molten metal and heated zones. For spot, seam, and flash welding, protective atmospheres may not be necessary, ensuring versatility in welding techniques.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to contamination from hydrogen (improper pickling) and from oxygen, nitrogen, and carbon during processes like forging and heat treating. Such contamination can lead to a loss of ductility, adversely impacting notch sensitivity and forming characteristics. Thus, maintaining a contamination-free environment is critical.

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. CP titanium exhibits excellent corrosion resistance to a wide variety 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 excellent resistance to crevice corrosion in salt solutions compared to stainless steels. It will 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 superb 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.
Seawater with velocities up to 130 ft/sec (40 m/sec) shows negligible impact on the material. Even in the presence of abrasive particles, such as sand, the corrosion effect remains minimal, ensuring long-lasting durability.
Hydrogen Embrittlement
Titanium exhibits no significant hydrogen absorption when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only when the following conditions are present:
- 1. The pH is < 3 or > 12
- 2. The temperature exceeds 176°F (80°C)
- 3. A mechanism for hydrogen generation exists, such as a galvanic couple or an impressed current.
Bio-Corrosion
Titanium alloys demonstrate remarkable immunity to all forms of microbiologically influenced corrosion. Although biofouling can occur due to the non-toxicity of titanium alloys toward marine organisms, it can be effectively minimized through chlorination or by increasing water velocity through the heat exchanger.
Corrosion Fatigue
Unlike many other materials, titanium does not suffer from decreased fatigue performance in seawater. Both fatigue endurance limits and fatigue *** growth rates remain consistent whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is positioned towards the noble end, near stainless steels. As a result, it typically acts as a cathode when coupled with other metals, avoiding galvanic corrosion but potentially accelerating the corrosion of the other metal. When coupled with more noble metals, such as graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rods exhibit no degradation in fatigue properties when exposed to seawater. Whether tested in air or seawater, fatigue endurance limits and fatigue *** growth rates remain unchanged.
Weldability
CP2 Grade Titanium Rods are highly weldable, provided the necessary precautions are followed. Due to titanium's reactivity, an inert gas shield must be used on both the exterior and interior of the rod, and the material must be free from grease or oil contamination.
Grade 2 Titanium Rods are typically welded using manual or automatic TIG welding methods, with or without filler wire. To minimize the heat-affected zone, low heat input is recommended. Post-weld heat treatment is generally not required for titanium rods.
