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 is performed at 1,700-1,900°F (927 - 1,038°C).
The DAXUN 6-4™ Grade 5 alloy is versatile and can be heat-treated in multiple ways. - 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
For optimal properties, rapid quenching of small sections in the solution-treated and aged condition is recommended. Larger sections or delayed quenching may result in reduced properties.
HARDNESS
Typically, the annealed condition yields a hardness of Rockwell C 30-34, while the solution and aged condition results in approximately Rockwell C 35-39.
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). To achieve optimum properties, a minimum reduction of 35% is recommended.
- The Ti-6Al-4V, Grade 5 alloy bar is inherently challenging to manipulate at room temperature, even when annealed. For intense forming operations like bending or stretching, these processes are best performed on annealed material at elevated temperatures up to 1,200°F (649°C) to maintain mechanical integrity. Hot sizing or forming can be effectively executed through creep forming within the temperature range of 1,000 - 1,200°F (538 - 649°C), ensuring mechanical properties remain unaffected.
Machinability
The Ti-6Al-4V, Grade 5 alloy bar showcases excellent machinability through methods typically employed for austenitic stainless steel. This involves slow machining speeds, high feed rates, the use of rigid tools, and liberal application of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is highly weldable in both the annealed and solution-processed, partially aged conditions, with aging effectively achieved during post-weld heat treatment. To avoid contamination by oxygen, nitrogen, and hydrogen, it is essential to perform fusion welding in an inert gas-filled chamber or use an inert gas shield for the molten metal and adjacent heated zones. Spot, seam, and flash welding can also be conducted without needing a protective atmosphere.
Special Considerations
Special care must be taken to prevent Ti-6Al-4V, Grade 5 titanium alloy rod contamination with hydrogen during improper pickling, or with oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such 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
The general corrosion rates for Grade 2 titanium across various media are depicted in Table 1. CP titanium demonstrates robust corrosion resistance in a wide array of environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion
CP titanium offers excellent resistance to crevice corrosion in salt solutions compared to stainless steels. CP titanium will not experience crevice corrosion at temperatures below 80°C (176°F), irrespective of pH, even under hyper-chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium excels in resisting stress corrosion cracking (SCC) in hot chloride solutions and remains unaffected by SCC in seawater.
Erosion Corrosion
Titanium exhibits superior resistance to erosion in dynamic conditions.
Seawater at velocities up to 130 ft/sec (40 m/sec) demonstrates negligible impact on the material. Even with the presence of abrasive particles like sand, the corrosion effect remains minimal.
Hydrogen Embrittlement
Titanium shows no significant absorption of hydrogen when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only if the following three conditions are met:
- 1. The pH is < 3 or > 12
- 2. Temperature exceeds 176F (80C)
- 3. A mechanism for hydrogen generation exists, such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys exhibit a unique immunity to microbiologically influenced corrosion. Despite not being toxic to marine organisms, which can lead to biofouling, this can be managed by chlorination or increasing water velocity in heat exchangers.
Corrosion Fatigue
Titanium maintains its fatigue performance in the presence of seawater, unlike many other materials. Fatigue endurance limits and *** 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, and typically functions as a cathode when paired with other metals. Titanium itself remains unaffected by galvanic corrosion but can accelerate the corrosion of the other metal. When coupled with more noble metals, such as graphite, titanium's passivity is enhanced.
Fatigue Properties
Grade 2 Titanium Rod maintains its fatigue properties even in seawater. Both its fatigue endurance limits and *** growth rates remain consistent whether in air or seawater.
Weldability
CP2 Grade Titanium Rod boasts excellent weldability provided necessary precautions are observed. An inert gas shield must cover both the outer and inner diameters of the rod due to titanium's reactivity. The material must also be free of grease or oil contamination.
Grade 2 Titanium Rod is typically welded using manual or automatic TIG welding, with or without filler wire. To minimize the heat-affected zone, low heat input should be employed. Post-weld heat treatment is generally not required for Titanium Rod.
