HEAT TREATMENT
- For applications demanding high hardness, tensile strength, and fatigue resistance, annealing can be conducted at temperatures between 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy can undergo various heat treatment methods. - 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, the rapid quenching of small sections ensures optimal properties. Larger sections or delayed quenching may result in suboptimal properties.
HARDNESS
Typical hardness in the annealed condition is Rockwell C 30-34, while in the solution and aged condition, it ranges around Rockwell C 35-39.
Forgeability/Formability
- Ti-6Al-4V, Grade 5 alloy bar is ideally forged at 1,750°F (954°C) with a final forging temperature of 1,450°F (788°C). A recommended minimum reduction of 35% is essential for achieving optimal properties.
- The Ti-6Al-4V, Grade 5 alloy bar, renowned for its high strength, is challenging to form at room temperature-even in its annealed state. Consequently, intense forming operations such as bending or stretching are best performed on annealed material at elevated temperatures up to 1,200°F (649°C), ensuring no compromise in mechanical properties. Hot sizing or forming can be effectively achieved by creep forming within the temperature range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar showcases excellent machinability when processed using austenitic stainless steel machining techniques. To optimize results, slow machining speeds, high feed rates, and rigid tooling are essential, supplemented by the use of abundant non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod offers superb weldability whether in the annealed condition or the solution and partially aged state. Aging is typically achieved during post-weld heat treatment. It is crucial to prevent contamination from oxygen, nitrogen, and hydrogen during the welding process. Fusion welding can be performed in an inert gas-filled chamber or with an inert gas shield to protect the molten metal and adjacent heated zones. Additionally, spot, seam, and flash welding can be executed without a protective atmosphere.
Special Considerations
Attention must be paid to prevent contamination of the Ti-6Al-4V, Grade 5 titanium alloy rod 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
Titanium should be avoided in environments involving strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General corrosion
The general corrosion rates for Grade 2 titanium in various media are presented in Table 1. CP titanium showcases excellent corrosion resistance in a broad spectrum of environments, including:
- Seawater and brines
- Inorganic salts
- Moist *** gas
- Alkaline solutions
- Oxidizing acids
- Organics and organic acids
- Sulfur compounds
Crevice corrosion
CP titanium demonstrates robust resistance to crevice corrosion in salt solutions when compared to stainless steels. It will not undergo crevice corrosion at temperatures below 80°C (176°F) regardless of pH, even under super chlorinated conditions.
Stress corrosion cracking
Grade 2 titanium exhibits outstanding resistance to stress corrosion cracking (SCC) in hot chloride solutions and remains immune in seawater.
Erosion corrosion
Titanium boasts outstanding resistance to erosion in dynamic environments, demonstrating exceptional durability even under the most demanding conditions.
In seawater velocities reaching up to 130 ft/sec (40 m/sec), titanium remains largely unaffected. The presence of abrasive particles, such as sand, only marginally impacts its corrosion resistance.
Hydrogen Embrittlement
Titanium does not significantly absorb hydrogen when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only under the following conditions:
- 1. pH levels are below 3 or above 12
- 2. Temperatures exceed 176°F (80°C)
- 3. There is a mechanism for hydrogen generation, such as a galvanic couple or imposed current.
Bio-Corrosion
Titanium alloys exhibit unique immunity to all forms of microbiologically influenced corrosion. However, due to their non-toxicity towards marine life, biofouling can occur. This can be mitigated through chlorination or by increasing water velocity in heat exchangers.
Corrosion Fatigue
Unlike many materials, titanium does not experience reduced fatigue performance in seawater. The fatigue endurance limits and *** 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. It typically acts as a cathode when coupled with other metals, hence titanium remains unscathed by galvanic corrosion while potentially accelerating the corrosion of the other metal. Coupling with more noble metals, such as graphite, further bolsters titanium's passivity.
Fatigue Properties
Grade 2 Titanium Rod shows unmatched fatigue properties, unaffected by exposure to seawater. The fatigue endurance limits and *** growth rates are consistent both in air and seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable with proper precautions. Given titanium's reactivity, an inert gas shield must be applied to both the OD and ID of the rod. The material must also be devoid of any grease or oil contamination.
Grade 2 Titanium Rods are typically welded using manual or automatic TIG welding, with or without filler wire, ensuring low heat input to minimize the heat-affected zone. Post weld heat treatment is generally unnecessary.
