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 applications demanding high 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 offers versatile heat treatment options to meet various performance requirements. - 1. Anneal: Conducted at 1,275 -1,400°F; (691 - 760°C) for ½ to 2 hours, followed by air or furnace cooling.
- 2. Stress Relief Anneal: Performed at 1,000 -1,200°F; (538 - 649°C) for 1 to 8 hours, then air or furnace cooled.
- 3. Solution Heat Treat: Executed at 1,675 -1,750°F; (913 - 954°C) for 1 hour, followed by water quenching.
- 4. Aging: Conducted at 975 -1,025°F; (524 - 552°C) for 4 to 8 hours, air cooled.
Rapid quenching of small sections in the solution treated and aged condition ensures optimum properties. Larger sections or delayed quenching may yield less than optimal properties.
HARDNESS
Typical hardness is Rockwell C 30-34 in the annealed condition, and Rockwell C 35-39 in the solution and aged condition.
Forgeability/Formability
- 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 for achieving optimum properties.
- The Ti-6Al-4V, Grade 5 titanium alloy rod, renowned for its exceptional strength and durability, poses challenges in forming at room temperature, even when annealed. However, it can undergo severe forming operations such as bending or stretching at temperatures up to 1,200°F (649°C) without compromising its mechanical properties. Hot sizing or forming is achievable through creep forming within the temperature range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 titanium alloy bar can be expertly machined using austenitic stainless steel machining methods. This process requires slow machining speeds, high feeds, rigid tools, and ample non-chlorinated cutting fluids, ensuring precision and efficiency.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is highly weldable in both the annealed condition and the solution and partially aged condition, with aging achieved during post-weld heat treatment. To prevent contamination from oxygen, nitrogen, and hydrogen, fusion welding should occur in an inert gas-filled chamber or using inert gas to protect the molten metal and adjacent heated zones. Spot, seam, and flash welding can be performed without a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod requires careful handling to avoid contamination from hydrogen during improper pickling and from oxygen, nitrogen, and carbon during forging, heat treating, and brazing. Such contamination can decrease ductility, affecting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion Resistance
Titanium should be avoided in environments with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion
The general corrosion rates for Grade 2 titanium in various media are displayed in Table 1. CP titanium demonstrates excellent corrosion resistance to a wide range of environments including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion
CP titanium has superior resistance to crevice corrosion in salt solutions compared to stainless steels. It resists crevice corrosion at temperatures below 80°C (176°F) regardless of pH, even under super-chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium offers 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 flowing environments.
Seawater with velocities up to 130 ft/sec (40 m/sec) shows negligible effect on the material. Even the presence of abrasive particles, such as sand, has minimal impact on corrosion, making this alloy remarkably resilient.
Hydrogen Embrittlement
There is no significant absorption of hydrogen into titanium when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only under the following three conditions:
- 1. The pH level is < 3 or > 12
- 2. Temperature exceeds 176°F (80°C)
- 3. A mechanism exists for hydrogen generation, such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys exhibit unparalleled immunity to all forms of microbiologically influenced corrosion. Despite being non-toxic to marine organisms, biofouling can occur in seawater but can be minimized through chlorination or by increasing water velocity through heat exchangers.
Corrosion Fatigue
Titanium, unlike many other materials, does not suffer a decrease in fatigue performance when exposed to seawater. The 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 paired with other metals. This means titanium is generally unaffected by galvanic corrosion but can accelerate the corrosion of the other metal. Pairing titanium with more noble metals, such as graphite, enhances its passivity.
Fatigue Properties
Grade 2 Titanium Rod stands out for its resistance to fatigue in seawater environments. Its fatigue endurance limits and fatigue *** growth rates remain unchanged whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable, provided the right precautions are taken. Due to titanium's reactivity, an inert gas shield should cover both the OD and ID of the rod. Ensure the material is free from grease or oil contamination.
Grade 2 Titanium Rod is commonly welded using manual or automatic TIG welding, with or without filler wire. Use low heat input to minimize the size of the heat-affected zone. Typically, post-weld heat treatment is not required.
