AMS 4965 - Bars, Forgings (Solution treated and aged)
AMS 4967 - Bars, Forgings (Annealed, Heat Treatable)
EXPERT HEAT TREATMENT
- For high hardness, tensile strength, and fatigue strength, annealing can be 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 smaller sections yields optimal properties. Larger sections or delayed quenching may reduce these properties.
ENHANCED HARDNESS
Typical hardness in the annealed state is Rockwell C 30-34, increasing to 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 reduction of 35% is recommended to achieve optimal properties.
- The Ti-6Al-4V, Grade 5 alloy bar presents challenges in forming at room temperature, even in an annealed state. For demanding operations like bending or stretching, it's advantageous to handle the material at elevated temperatures up to 1,200°F (649°C) to maintain its mechanical integrity. Hot sizing and forming are best executed through creep forming within the range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar exhibits excellent machinability using techniques similar to those for austenitic stainless steel. Employ slow machining speeds, high feeds, and rigid tooling, complemented by generous quantities of non-chlorinated cutting fluids to achieve optimal results.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is highly weldable in both the annealed condition and the solution and partially aged condition. Aging can be achieved during post-weld heat treatment. To prevent contamination from oxygen, nitrogen, and hydrogen, fusion welding should occur in an inert gas environment or use inert gas to shield the molten and adjacent heated zones. Spot, seam, and flash welding are possible without needing a protective atmosphere, but precautions are necessary.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rods are susceptible to hydrogen contamination from improper pickling and can also absorb oxygen, nitrogen, and carbon during processes like forging, heat treating, or brazing. Such contamination may reduce ductility, increasing notch sensitivity and adversely affecting forming characteristics.

Grade 2 Titanium Rod
Exceptional Corrosion Resistance
Avoid using Titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion Resistance
Grade 2 Titanium's general corrosion rates in various media are illustrated in Table 1. Commercially pure titanium (CP titanium) displays robust resistance to corrosion in a multitude of environments, such as:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organic Compounds and Organic Acids
- Sulfur Compounds
Crevice Corrosion Resistance
CP Titanium exhibits superior resistance to crevice corrosion in saline solutions when compared to stainless steels. CP Titanium remains free from crevice corrosion at temperatures below 80 °C (176°F), regardless of pH, even under superchlorinated conditions.
Stress Corrosion Cracking Resistance
Grade 2 Titanium demonstrates outstanding resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion Resistance
Titanium displays excellent resistance to erosion in flowing environments.
The Titanium Rod Gr5 shows remarkable resistance to seawater, even at velocities reaching up to 130 ft/sec (40 m/sec). This high-performance material remains virtually unaffected, even in the presence of abrasive particles like sand, which have only a minimal impact on its corrosion resistance.
Hydrogen Embrittlement
Titanium exposed to seawater does not significantly absorb hydrogen, even at elevated temperatures. Hydrogen absorption in titanium generally occurs only under the following specific conditions:
- 1. The pH level is either below 3 or above 12.
- 2. The temperature exceeds 176°F (80°C).
- 3. A mechanism exists for hydrogen generation, such as a galvanic couple or an impressed current.
Bio-Corrosion
Titanium alloys exhibit exceptional immunity to all forms of microbiologically influenced corrosion. Although these alloys are non-toxic to marine organisms, which may lead to biofouling in seawater, this can be effectively managed by chlorination or by increasing water velocity through heat exchangers.
Corrosion Fatigue
Unlike many other materials, titanium does not suffer from reduced fatigue performance in seawater. The fatigue endurance limits and fatigue *** growth rates of titanium remain consistent whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium lies near the noble end, close to stainless steels, and generally acts as the cathode when paired with other metals. While titanium remains unaffected by galvanic corrosion, it may accelerate the corrosion of the coupled metal. Pairing titanium with more noble metals, such as graphite, further enhances its passivity.
Fatigue Properties
Grade 2 Titanium Rod maintains its fatigue properties in seawater, without degradation. The fatigue endurance limits and fatigue *** growth rates are identical whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod boasts excellent weldability, provided that specific precautions are taken. Due to titanium's reactivity, an inert gas shield must protect both the OD and ID of the rod. Additionally, the material should be free from any grease or oil contamination.
Typically, Grade 2 Titanium Rod is welded using manual or automatic TIG welding, with or without filler wire. It is crucial to use low heat input to minimize the heat-affected zone size. Post-weld heat treatment is not commonly required for Titanium Rods.
