AMS 4965 - Bars, Forgings (Solution treated and aged)
AMS 4967 - Bars, Forgings (Annealed, Heat Treatable)
HEAT TREATMENT
- For applications demanding 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), hold for ½ to 2 hours, then air or furnace cool.
- 2. Stress Relief Anneal: 1,000 -1,200°F; (538 - 649°C), hold for 1 to 8 hours, then air or furnace cool.
- 3. Solution Heat Treat: 1,675 -1,750°F; (913 - 954°C), hold for 1 hour, then water quench.
- 4. Aging: 975 -1,025°F; (524 - 552°C), hold for 4 to 8 hours, then air cool.
In the solution-treated and aged condition, rapid quenching of small sections yields optimal properties. For larger sections, delays in quenching may result in suboptimal properties.
HARDNESS
Typical hardness ranges are Rockwell C 30-34 in the annealed state and approximately Rockwell C 35-39 in the solution-treated and aged state.
Forgeability/Formability
- The Ti-6Al-4V, Grade 5 alloy bar is best forged at 1,750°F (954°C) with a final forging temperature of 1,450°F (788°C). Achieving a minimum of 35% reduction is recommended for optimum material properties.
- The Ti-6Al-4V, Grade 5 alloy bar is challenging to form at room temperature, even when annealed. For severe forming operations like bending or stretching, it can be shaped in annealed form at temperatures up to 1,200°F (649°C) without altering its mechanical properties. Additionally, hot sizing or forming can be accomplished through creep forming within the range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar can be efficiently machined using methods suited for austenitic stainless steel. This includes employing slow machining speeds, high feeds, sturdy tools, and using large amounts of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is highly weldable whether in its annealed state or in a solution and partially aged condition, with the aging process carried out during post-weld heat treatment. Precautions must be taken to avoid contamination with oxygen, nitrogen, and hydrogen. Fusion welding can be performed in an inert gas chamber or by using inert gas to protect the molten metal and adjacent heated zones, supplemented with a tail shield. Spot, seam, and flash welding are feasible without a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod can be contaminated with hydrogen from improper pickling and with oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such contamination can lead to a loss of ductility, negatively impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion Resistance
Important Note: Titanium should not be exposed to strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion
The general corrosion rates for Grade 2 titanium across various media are illustrated in Table 1. CP titanium demonstrates superior corrosion resistance in several 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. It remains unaffected by crevice corrosion at temperatures below 80°C (176°F), even under super-chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium shows exceptional resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion
Titanium exhibits outstanding resistance to erosion in dynamic environments.
Withstanding seawater velocities up to 130 ft/sec (40 m/sec), our titanium rods demonstrate negligible material degradation. Even the presence of abrasive particles, such as sand, causes only minimal corrosion.
Hydrogen Embrittlement
Titanium shows no significant hydrogen absorption even in seawater at elevated temperatures. Generally, hydrogen absorption only occurs when three specific conditions are met:
- pH levels are < 3 or > 12
- Temperature exceeds 176F (80C)
- A mechanism for hydrogen generation exists, such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys exhibit unparalleled immunity to microbiologically influenced corrosion. However, biofouling can occur in seawater due to non-toxicity towards marine life, but this can be mitigated by chlorination or increasing water velocity through heat exchangers.
Corrosion Fatigue
Unlike many materials, titanium shows no decrease in fatigue performance in seawater. Fatigue endurance limits and *** growth rates remain consistent whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is near the noble end alongside stainless steels, usually acting as the cathode when paired with other metals. Thus, titanium remains unaffected by galvanic corrosion while potentially accelerating the corrosion of the other metal. Pairing titanium with more noble metals, such as graphite, enhances its passivity.
Fatigue Properties
Grade 2 Titanium Rod maintains its fatigue properties even in seawater. Its fatigue endurance limits and *** growth rates are consistent in both air and seawater environments.
Weldability
CP2 Grade Titanium Rod is highly weldable with proper precautions. Due to titanium's reactivity, an inert gas shield must be used on both the OD and ID of the rod, and the material must 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. To minimize the heat-affected zone, low heat input is recommended. Post-weld heat treatment is generally not required for Titanium Rod.
