AMS 4965 - Bars, Forgings (Solution treated and aged)
AMS 4967 - Bars, Forgings (Annealed, Heat Treatable)
HEAT TREATMENT PROCESSES
- For superior hardness, tensile strength, and fatigue strength, annealing is performed at temperatures ranging from 1,700-1,900°F (927-1,038°C).
DAXUN 6-4™ Grade 5 alloy can undergo multiple heat treatment processes. - 1. Anneal: 1,275 - 1,400°F; (691 - 760°C), for ½ to 2 hours, with air or furnace cooling.
- 2. Stress Relief Anneal: 1,000 - 1,200°F; (538 - 649°C), for 1 to 8 hours, with air or furnace cooling.
- 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, with air cooling.
In the solution treated and aged condition, rapid quenching of small sections yields optimal properties. Larger sections or delayed quenching may result in suboptimal properties.
HARDNESS PROPERTIES
In the annealed condition, typical hardness ranges from Rockwell C 30-34, while in the solution treated and aged condition, it ranges from Rockwell C 35-39.
Forgeability and 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 optimum properties.
- The Ti-6Al-4V, Grade 5 alloy bar presents challenges in forming at room temperature, even when annealed. However, severe forming operations such as bending or stretching can be executed on annealed material at elevated temperatures up to 1,200°F (649°C) without compromising its mechanical properties. For hot sizing or forming, creep forming is an effective method within the temperature range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar is machined effectively using austenitic stainless steel machining methods. This involves slow machining speeds, high feed rates, rigid tools, and the liberal use of non-chlorinated cutting fluids to ensure precise results.
Weldability
Ti-6Al-4V, Grade 5 alloy rod exhibits excellent weldability in both the annealed and solution-aged conditions. Aging is achieved during post-weld heat treatment. Strict precautions are necessary to prevent contamination with oxygen, nitrogen, and hydrogen. Fusion welding should be conducted in an inert gas-filled chamber or with inert gas shielding. Spot, seam, and flash welding can be performed without needing a protective atmosphere.
Special Considerations
During processes like pickling, forging, heat treating, and brazing, Ti-6Al-4V, Grade 5 titanium alloy rod may suffer contamination from hydrogen, oxygen, nitrogen, and carbon. This contamination can reduce ductility, negatively impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion Resistance
Titanium should avoid contact with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion
Table 1 illustrates the general corrosion rates for Grade 2 titanium in various media. CP titanium demonstrates robust corrosion resistance in diverse environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion
CP titanium showcases excellent resistance to crevice corrosion in salt solutions compared to stainless steels. It remains unaffected by crevice corrosion at temperatures below 80°C (176°F), irrespective of pH, even under super chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium offers outstanding resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion
Titanium demonstrates exceptional resistance to erosion in flowing conditions.
Seawater velocities reaching up to 130 ft/sec (40 m/sec) show negligible effect on the material's integrity. Even with the presence of abrasive particles like sand, the corrosion impact remains minimal.
Hydrogen Embrittlement
Titanium exhibits no significant hydrogen absorption when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only under the following conditions:
- pH levels are < 3 or > 12
- Temperature exceeds 176°F (80°C)
- A mechanism for hydrogen generation, such as a galvanic couple or impressed current, is present.
Bio-Corrosion
Titanium alloys demonstrate exceptional immunity to all forms of microbiologically influenced corrosion. Although these alloys do not exhibit toxicity towards marine organisms, biofouling can occur in seawater. This can be mitigated through chlorination or by increasing water velocity within the heat exchanger.
Corrosion Fatigue
Unlike many materials, titanium shows no reduction in fatigue performance in seawater. Fatigue endurance limits and *** growth rates remain consistent whether tested in air or seawater environments.
Galvanic Corrosion
On the galvanic series, titanium is positioned towards the noble end near stainless steels, typically acting as the cathode when paired with other metals. Titanium itself is unaffected by galvanic corrosion but can accelerate the corrosion of less noble metals. Coupling titanium with noble metals, such as graphite, further enhances its passivity.
Fatigue Properties
Grade 2 Titanium Rod does not exhibit degradation in fatigue properties when exposed to seawater. Fatigue endurance limits and *** growth rates are consistent whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod offers excellent weldability when proper 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 grease or oil contamination.
Grade 2 Titanium Rod is typically welded using manual or automatic TIG welding, with or without filler wire. Utilizing low heat input is crucial to minimize the heat affected zone. Post-weld heat treatment is generally not required for Titanium Rod.
