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 done at temperatures ranging from 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy is versatile in heat treatment methods. - 1. Anneal: 1,275 -1,400°F; (691 - 760°C) for ½ to 2 hours, followed by air or furnace cooling.
- 2. Stress Relief Anneal: 1,000 -1,200°F; (538 - 649°C) for 1 to 8 hours, then air or furnace cool.
- 3. Solution Heat Treat: 1,675 -1,750°F; (913 - 954°C) for 1 hour, followed by water quenching.
- 4. Aging: 975 -1,025°F; (524 - 552°C) for 4 to 8 hours, followed by air cooling.
In the solution treated and aged condition, rapid quenching of small sections achieves optimal properties. However, larger sections and delayed quenching may yield slightly lower properties.
HARDNESS
Typically, the hardness in the annealed condition ranges from Rockwell C 30-34, and Rockwell C 35-39 in the solution treated 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 reduction of 35% is recommended to achieve optimal properties.
- Ti-6Al-4V, Grade 5 alloy bar is notoriously challenging to form at room temperature, even when annealed. However, intense forming operations such as bending or stretching can be successfully executed on annealed material at elevated temperatures up to 1,200°F (649°C) without compromising its mechanical integrity. Hot sizing or forming is feasible through creep forming within the temperature range of 1,000 - 1,200°F (538 - 649°C).
Machinability
Ti-6Al-4V, Grade 5 alloy bar can be precisely machined using techniques common to austenitic stainless steel, albeit with slower machining speeds, higher feeds, and the utilization of rigid tools. Copious amounts of non-chlorinated cutting fluids are essential for optimum results.
Weldability
Ti-6Al-4V, Grade 5 alloy rod offers excellent weldability in both annealed and solution plus partially aged conditions. Post-weld heat treatment is used for aging. Care must be taken to avoid contamination by oxygen, nitrogen, and hydrogen. Fusion welding is ideally performed in an inert gas-filled chamber or with inert gas shielding to protect the molten metal and adjacent heated zones. Additionally, spot, seam, and flash welding are possible without a protective atmosphere.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rod can suffer from hydrogen contamination due to improper pickling and from oxygen, nitrogen, and carbon during forging, heat treating, and brazing processes. This contamination can lead to reduced 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
Table 1 presents general corrosion rates for Grade 2 titanium in various media. CP titanium offers outstanding corrosion resistance in numerous environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion
CP titanium demonstrates robust resistance to crevice corrosion in salt solutions, outperforming stainless steels. It remains resistant to crevice corrosion at temperatures below 80°C (176°F), irrespective of pH, even under super chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium excels in resisting stress corrosion cracking (SCC) in hot chloride solutions and remains immune to SCC in seawater.
Erosion Corrosion
Titanium demonstrates outstanding resistance to erosion in dynamic environments,
even in seawater velocities reaching up to 130 ft/sec (40 m/sec), with negligible impact on the material. The presence of abrasive particles, such as sand, exerts only a minor influence on corrosion.
Hydrogen Embrittlement
Titanium exposed to seawater shows no significant hydrogen absorption, even at elevated temperatures. Hydrogen absorption typically occurs only when all of the following conditions are met:
- 1. pH is < 3 or > 12
- 2. Temperature exceeds 176°F (80°C)
- 3. A mechanism for hydrogen generation exists, such as a galvanic couple or impressed current.
Bio-corrosion
Titanium alloys exhibit unique immunity to all forms of microbiologically influenced corrosion. Although titanium alloys are non-toxic to marine organisms, biofouling can occur in seawater. This can be mitigated by chlorination or by increasing the water velocity through the heat exchanger.
Corrosion Fatigue
Unlike many other materials, titanium does not experience reduced fatigue performance in seawater. Fatigue endurance limits and fatigue *** growth rates remain consistent whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is positioned near the noble end, close to stainless steels, and typically acts as the cathode when coupled with other metals. Titanium remains unaffected by galvanic corrosion but can accelerate corrosion in the coupled metal. Coupling titanium with more noble metals, such as graphite, enhances titanium's passive nature.
Fatigue Properties
Grade 2 Titanium Rod does not suffer degradation in fatigue properties in seawater. The fatigue endurance limits and fatigue *** growth rates are the same whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod offers excellent weldability when appropriate precautions are taken. Due to titanium's reactivity, an inert gas shield must be applied to both the OD and ID of the rod. The material must also be free from any grease or oil contamination.
Grade 2 Titanium Rod is typically welded using manual or automatic TIG welding, with or without filler wire. Low heat input is recommended to minimize the size of the heat affected zone. Post weld heat treatment is generally not required for Titanium Rod.
