HEAT TREATMENT
- For applications requiring high hardness, tensile strength, and fatigue resistance, annealing processes are conducted at 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy can undergo various heat treatment processes. - 1. Anneal: 1,275 -1,400°F; (691 - 760°C), ½ to 2 hours, followed by air or furnace cooling.
- 2. Stress Relief Anneal: 1,000 -1,200°F; (538 - 649°C), 1 to 8 hours, followed by air or furnace cooling.
- 3. Solution Heat Treat: 1,675 -1,750°F; (913 - 954°C), 1 hour, followed by water quenching.
- 4. Aging: 975 -1,025°F; (524 - 552°C), 4 to 8 hours, followed by air cooling.
In the solution treated and aged condition, rapid quenching of small sections yields optimal properties. Larger sections and/or delayed quenching can result in suboptimal properties.
HARDNESS
The typical hardness is Rockwell C 30-34 in the annealed condition, and Rockwell C 35-39 in the solution 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). A minimum reduction of 35% is recommended for achieving optimal properties.
- Ti-6Al-4V, Grade 5 alloy bar presents a formidable challenge when it comes to forming at room temperature, even in its annealed state. To manage severe forming operations like bending or stretching, these must be performed on annealed material at elevated temperatures up to 1,200°F (649°C) without compromising mechanical properties. Hot sizing or forming can be effectively executed by employing creep forming within the temperature range of 1,000 - 1,200°F (538 - 649°C).
Machinability
Ti-6Al-4V, Grade 5 alloy bar can be expertly machined using the same techniques as those for austenitic stainless steel. This involves slow machining speeds, high feed rates, rigid tools, and the extensive use of non-chlorinated cutting fluids to ensure precision and quality.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod exhibits excellent weldability in its annealed condition or when solution-treated and partially aged, with aging occurring 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 to protect the molten metal and adjacent heated zones, using a tail shield for additional safety. Spot, seam, and flash welding can be conducted without a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to hydrogen contamination from improper pickling, and oxygen, nitrogen, and carbon contamination during forging, heat treating, or brazing. Such contamination can result in a loss of ductility, which may negatively impact notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion Resistance
Titanium should be avoided in environments containing strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion
Grade 2 titanium demonstrates excellent general corrosion resistance in a variety of media, as shown in Table 1. Commercially Pure (CP) titanium is notably resilient against a broad spectrum of environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organic and Organic Acids
- Sulfur Compounds
Crevice Corrosion
CP titanium offers robust resistance to crevice corrosion in salt solutions, outperforming stainless steels. It remains unaffected by crevice corrosion at temperatures below 80°C (176°F) regardless of pH, even in highly chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium exhibits exceptional resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion
Titanium showcases superior resistance to erosion in flowing environments.
Our Pure Titanium Rod Gr1 withstands seawater velocities up to 130 ft/sec (40 m/sec) virtually unaffected. Even abrasive particles, such as sand, cause only minimal corrosion impact.
Hydrogen Embrittlement Concerns
Titanium shows no significant hydrogen absorption when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only under the following conditions:
- When the pH is less than 3 or greater than 12.
- When the temperature exceeds 176°F (80°C).
- When a mechanism for hydrogen generation exists, such as a galvanic couple or an impressed current.
Bio-Corrosion Resistance
Titanium alloys exhibit unique immunity to microbiologically influenced corrosion. Though biofouling can occur in seawater due to the alloys' non-toxic nature towards marine organisms, this can be minimized via chlorination or by increasing water velocity through heat exchangers.
Corrosion Fatigue Resistance
Unlike many other materials, titanium does not experience a decrease in fatigue performance in seawater. Fatigue endurance limits and *** growth rates remain consistent whether tested in air or seawater.
Galvanic Corrosion Dynamics
In the galvanic series, titanium is near the noble end, close to stainless steels, and typically acts as a cathode when paired with other metals. While titanium is unaffected by galvanic corrosion, it can accelerate the corrosion of the coupled metal. Coupling with more noble metals, like graphite, enhances titanium's passivity.
Outstanding Fatigue Properties
Grade 2 Titanium Rod maintains its fatigue properties in seawater, showing no degradation. Fatigue endurance limits and *** growth rates are consistent whether in air or seawater.
Exceptional Weldability
CP2 Grade Titanium Rod is highly weldable with proper precautions. Due to its reactivity, an inert gas shield is necessary on both the OD and ID of the rod, and the material must be clean of any grease or oil.
Typically, Grade 2 Titanium Rod is welded using TIG welding, manually or automatically, with or without filler wire. Low heat input is recommended to minimize the heat-affected zone. Post-weld heat treatment is usually unnecessary.
