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 superior hardness, tensile strength, and fatigue strength, annealing can be conducted at temperatures between 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy can undergo a variety of heat treatment processes. - 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.
Rapid quenching of small sections in solution treated and aged condition offers optimum properties, while larger sections or delayed quenching may result in suboptimal properties.
HARDNESS
In the annealed condition, typical hardness is Rockwell C 30-34. In the solution and aged condition, it ranges between 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). A minimum reduction of 35% is recommended to achieve optimum properties.
- The Ti-6Al-4V, Grade 5 alloy bar presents challenges when formed at room temperature, even in its annealed state. Such severe forming operations, including bending or stretching, are best conducted on annealed material within temperatures up to 1,200°F (649°C) to maintain mechanical integrity. Additionally, hot sizing or forming can be efficiently achieved through creep forming in the range of 1,000 - 1,200°F (538 - 649°C).
Machinability
Machining the Ti-6Al-4V, Grade 5 alloy bar is feasible using methods employed for austenitic stainless steel, albeit with slow machining speeds, high feeds, rigid tooling, and substantial volumes of non-chlorinated cutting fluids to ensure precision and efficiency.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod exhibits excellent weldability in both the annealed state and the solution and partially aged condition, with subsequent aging during post-weld heat treatment. Careful measures must be taken to avoid contamination from oxygen, nitrogen, and hydrogen. Fusion welding should be conducted in an inert gas-filled chamber or under an inert gas shield to protect the molten metal and adjacent heated zones. Spot, seam, and flash welding can be performed without a protective atmosphere, ensuring flexibility in welding techniques.
Special Considerations
Care must be taken to avoid contamination of the Ti-6Al-4V, Grade 5 titanium alloy rod with hydrogen (from improper pickling) or with oxygen, nitrogen, and carbon during processes such as forging, heat treating, and brazing. Such contamination can reduce ductility, negatively impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion Resistance
Titanium is not recommended for use with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion
Table 1 showcases the general corrosion rates for Grade 2 titanium across various media. Commercially Pure (CP) titanium demonstrates exceptional corrosion resistance in diverse environments such as:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion
CP Titanium provides superior resistance to crevice corrosion in salt solutions compared to stainless steels, with no crevice corrosion at temperatures below 80°C (176°F) regardless of pH, even under super chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium excels in resisting stress corrosion cracking (SCC) in hot chloride solutions and remains immune to SCC in seawater.
Erosion Corrosion
Titanium stands out with excellent resistance to erosion in flowing environments.
Seawater with velocities up to 130 ft/sec (40 m/sec) shows negligible effects on the material. Even the presence of abrasive particles, like sand, has only a minimal impact on corrosion.
Hydrogen Embrittlement
Titanium absorbs negligible hydrogen when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only under three specific conditions:
- pH is < 3 or > 12
- Temperature is above 176°F (80°C)
- A mechanism for hydrogen generation exists, such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys exhibit exceptional immunity to all forms of microbiologically influenced corrosion. Biofouling in seawater can occur, but this can be minimized through chlorination or increasing water velocity through a heat exchanger.
Corrosion Fatigue
Unlike many other materials, titanium does not experience decreased 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 near the noble end, close to stainless steels, and generally acts as the cathode when coupled with other metals. Thus, titanium is unaffected by galvanic corrosion but can accelerate the corrosion of the other metal. When coupled with more noble metals like graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod maintains its fatigue properties in seawater, with no degradation in fatigue endurance limits or *** growth rates.
Weldability
CP2 Grade Titanium Rod offers excellent weldability when proper precautions are taken. Due to titanium's reactivity, an inert gas shield must be placed on both the OD and ID of the rod, and the material must be free of grease or oil contamination.
Grade 2 Titanium Rod is generally welded using manual or automatic TIG welding, with or without filler wire. Utilizing low heat input minimizes the heat-affected zone. Post-weld heat treatment is typically unnecessary.
