SPECIFICATIONS
AMS 4928 - Bars, Forgings, and Forging Stock (Annealed)
AMS 4965 - Bars, Forgings (Solution Treated and Aged)
AMS 4967 - Bars, Forgings (Annealed, Heat Treatable)
HEAT TREATMENT
- For achieving high hardness, tensile strength, and fatigue strength, annealing is recommended at 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy offers versatile heat treatment options to meet various requirements. - 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 ensures optimal properties. Larger sections and/or delayed quenching may result in properties that are less than optimal.
HARDNESS
Typically, the hardness in the annealed condition is 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). To achieve optimal properties, a minimum reduction of 35% is recommended.
- Ti-6Al-4V, Grade 5 alloy bars are challenging to form at room temperature, even when annealed. However, severe forming such as bending or stretching can be performed on annealed materials at temperatures up to 1,200°F (649°C) without compromising mechanical properties. Hot sizing or forming can be achieved through creep forming within the range of 1,000 - 1,200°F (538 - 649°C).
Machinability
Ti-6Al-4V, Grade 5 alloy bars can be machined using methods designed for austenitic stainless steel, with slow machining speeds, high feeds, rigid tools, and substantial amounts of non-chlorinated cutting fluids to ensure precision.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is easily weldable in both the annealed condition and the solution and partially aged condition. The aging process occurs during post-weld heat treatment. It is crucial to prevent contamination with oxygen, nitrogen, and hydrogen. Fusion welding can be performed in an inert gas-filled chamber or with inert gas to protect the molten metal and adjacent heated zones, using a tail shield. Spot, seam, and flash welding can be done without a protective atmosphere.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rods may suffer from hydrogen contamination during improper pickling, as well as contamination from oxygen, nitrogen, and carbon during forging, heat treating, brazing, etc. This contamination can lead to a loss of ductility, adversely affecting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion resistance
Avoid using titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General corrosion
The corrosion resistance of Grade 2 titanium across various media is detailed in Table 1. CP titanium boasts excellent corrosion resistance in many different environments, including:
- Seawater and brines
- Inorganic salts
- Moist *** gas
- Alkaline solutions
- Oxidizing acids
- Organic compounds and acids
- Sulfur compounds
Crevice corrosion
CP titanium shows superior 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) regardless of pH, even under highly chlorinated conditions.
Stress corrosion cracking
Grade 2 titanium showcases unparalleled resistance to stress corrosion (SCC) cracking in hot chloride solutions and remains completely immune to SCC in seawater environments.
Erosion Corrosion
Titanium exhibits outstanding resistance to erosion in flowing environments.
Seawater velocities up to 130 ft/sec (40 m/sec) have a negligible effect on titanium. Even the presence of abrasive particles, such as sand, has minimal impact on its corrosion resistance.
Hydrogen Embrittlement
Titanium shows no significant hydrogen absorption when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only when these three conditions are met:
- pH is < 3 or > 12
- Temperature exceeds 176°F (80°C)
- 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 biofouling can occur because they do not exhibit toxicity toward marine organisms, it can be minimized by chlorination or increasing water velocity through heat exchangers.
Corrosion Fatigue
Unlike many other materials, titanium does not show 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 toward the noble end near stainless steels and typically acts as the cathode when paired with other metals. Thus, titanium is resistant to galvanic corrosion but can accelerate the corrosion of the paired metal. Coupling titanium with more noble metals, such as graphite, further enhances its passivity.
Fatigue Properties
Grade 2 Titanium Rod does not exhibit degradation in fatigue properties in the presence of seawater. The fatigue endurance limits and fatigue *** growth rates are unchanged whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable with necessary precautions. Due to titanium's reactivity, an inert gas shield must be applied to both the rod's OD and ID. 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. Low heat input is recommended to minimize the heat-affected zone. Post-weld heat treatment is generally not required.
