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
- To achieve high hardness, tensile strength, and fatigue strength, annealing can be performed at temperatures ranging from 1,700-1,900°F (927-1,038°C).
DAXUN 6-4™ Grade 5 alloy is versatile and can undergo various heat treatments. - 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 small sections yields optimal properties. However, larger sections and/or delayed quenching may lead to suboptimal properties.
HARDNESS
Typically, the hardness in the annealed condition is Rockwell C 30-34, while in the solution treated and aged condition, it ranges from Rockwell C 35-39.
Forgeability/Formability
- The Ti-6Al-4V, Grade 5 alloy bar is expertly forged at a temperature of 1,750°F (954°C), with the final forging temperature reaching 1,450°F (788°C). To achieve optimal properties, a minimum reduction of 35% is strongly recommended.
- Despite the difficulty of forming the Ti-6Al-4V, Grade 5 alloy bar at room temperature-even when annealed-severe forming operations like bending or stretching can be effectively performed on annealed material at elevated temperatures up to 1,200°F (649°C) without compromising mechanical properties. Hot sizing or forming is achievable through creep forming within a range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar can be machined using methods typically used for austenitic stainless steel, requiring slow machining speeds, high feeds, rigid tools, and abundant amounts of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is easily weldable in both the annealed condition or post-solution and partially aged condition, with aging being possible during post-weld heat treatment. It is crucial to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding should be performed in an inert gas-filled chamber or with inert gas shielding the molten metal and adjacent heated zones, using a tail shield. Spot, seam, and flash welding can be conducted without a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod may become contaminated with hydrogen from improper pickling, and with oxygen, nitrogen, and carbon during processes such as forging, heat treating, and brazing. This contamination can reduce 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 in various media are shown in Table 1. CP titanium exhibits excellent corrosion resistance to a wide variety 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 good resistance to crevice corrosion in salt solutions when compared to stainless steels. CP titanium will not exhibit crevice corrosion at temperatures below 80 °C (176°F) irrespective of pH, even under highly chlorinated conditions.
Stress corrosion cracking
Grade 2 titanium exhibits unparalleled resistance to stress corrosion (SCC) cracking in hot chloride solutions, maintaining immunity even in seawater environments.
Erosion Corrosion
Titanium demonstrates extraordinary resistance to erosion in flowing environments.
Even in seawater with velocities up to 130 ft/sec (40 m/sec), titanium shows negligible effects from erosion, and the presence of abrasive particles like sand has minimal impact on corrosion.
Hydrogen Embrittlement
Titanium absorbs negligible hydrogen when exposed to seawater, even at elevated temperatures. Hydrogen absorption only occurs under these specific conditions:
- 1. The pH level is < 3 or > 12
- 2. Temperature exceeds 176°F (80°C)
- 3. There is a mechanism for hydrogen generation, such as a galvanic couple or an impressed current.
Bio-Corrosion
Titanium alloys are uniquely immune to microbiologically influenced corrosion. Although biofouling can occur in seawater due to non-toxicity to marine organisms, this can be mitigated through chlorination or increased water velocity in heat exchangers.
Corrosion Fatigue
Unlike many materials, titanium maintains its fatigue performance in seawater, with both fatigue endurance limits and *** growth rates remaining consistent whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is positioned near the noble end, similar to stainless steels, typically acting as a cathode when coupled with other metals. This means titanium is resistant to 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 Rods showcase resilience, with no degradation in fatigue properties in seawater. Endurance limits and *** growth rates remain stable whether in air or seawater.
Weldability
CP2 Grade Titanium Rods are highly weldable with proper precautions. Due to titanium's reactivity, an inert gas shield must cover both the exterior and interior of the rod, and the material must be free of contaminants like grease or oil.
Grade 2 Titanium Rods are typically welded using manual or automatic TIG welding, with or without filler wire. Low heat input minimizes the heat-affected zone, and post-weld heat treatment is generally not required.
