ADVANCED HEAT TREATMENT
- For applications necessitating high hardness, tensile strength, and fatigue resistance, annealing can be conducted at temperatures ranging from 1,700 to 1,900°F (927 - 1,038°C).
The DAXUN 6-4™ Grade 5 alloy offers versatile heat treatment options. - 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. For larger sections or in cases of delayed quenching, optimal properties may not be fully achieved.
HARDNESS PARAMETERS
Typical hardness levels in the annealed condition range from Rockwell C 30-34, increasing to Rockwell C 35-39 in the solution treated and aged condition.
FORGEABILITY/FORMABILITY
- The Ti-6Al-4V, Grade 5 alloy bar is optimally 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 the best properties.
- The Ti-6Al-4V, Grade 5 alloy bar, known for its formidable strength, presents challenges when forming at room temperature, even in an annealed state. To achieve severe forming operations like bending or stretching, the alloy can be heated up to 1,200°F (649°C) without compromising its mechanical properties. For hot sizing or forming, creep forming is recommended within the range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The machinability of Ti-6Al-4V, Grade 5 alloy bar is optimized using methods tailored for austenitic stainless steel. This includes employing slow machining speeds, high feeds, sturdy tools, and abundant use of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod boasts excellent weldability, whether in an annealed, solution, or partially aged state. Post-weld aging is achievable during heat treatment. To maintain integrity, it is crucial to avoid contamination from oxygen, nitrogen, and hydrogen. Fusion welding can be effectively performed in an inert gas-filled chamber or with an inert gas shield to protect molten metal and adjacent zones. Additionally, spot, seam, and flash welding are feasible without requiring a protective atmosphere.
Special Considerations
When handling Ti-6Al-4V, Grade 5 titanium alloy rod, be aware of potential contamination risks. Improper pickling can lead to hydrogen contamination, while forging, heat treating, or brazing may introduce oxygen, nitrogen, and carbon. Such contamination could reduce ductility, adversely affecting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Exceptional Corrosion Resistance
Titanium should be avoided with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion Characteristics
Table 1 details general corrosion rates for Grade 2 titanium in diverse media. CP titanium excels in corrosion resistance across a broad range of environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion Resistance
CP titanium offers superior crevice corrosion resistance in saline solutions compared to stainless steels, showing no crevice corrosion at temperatures below 80 °C (176°F) regardless of pH, even under highly chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium demonstrates outstanding resistance to stress corrosion cracking (SCC) in hot chloride solutions and remains immune to sec in seawater.
Erosion Corrosion
Titanium exhibits excellent resistance to erosion in flowing environments.
The material withstands seawater velocities up to 130 ft/sec (40 m/sec) with negligible impact. Even abrasive particles like sand have minimal effect on its corrosion resistance.
Hydrogen Embrittlement
Titanium shows no significant hydrogen absorption in seawater, even at elevated temperatures. Hydrogen absorption typically only occurs when these three conditions are met:
- pH is less than 3 or greater than 12
- Temperature exceeds 176°F (80°C)
- A mechanism for hydrogen generation exists, such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys exhibit exceptional resistance to microbiologically influenced corrosion. Although biofouling can occur due to their non-toxicity towards marine organisms, this can be mitigated through chlorination or by increasing the water velocity in heat exchangers.
Corrosion Fatigue
Unlike many other materials, titanium does not exhibit decreased fatigue performance in seawater. Fatigue endurance limits and *** growth rates remain consistent whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is near the noble end close to stainless steels and typically acts as the cathode when coupled with other metals. Thus, titanium remains unaffected by galvanic corrosion but can accelerate the corrosion of the other metal. When paired with more noble metals like graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod maintains its fatigue properties in seawater, showing no degradation. Both fatigue endurance limits and *** growth rates remain unchanged, whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable with proper precautions. Due to titanium's reactivity, an inert gas shield must cover both the OD and ID of the rod. The material should be free from grease or oil contamination.
Grade 2 Titanium Rods are commonly welded using manual or automatic TIG welding, with or without filler wire. Low heat input helps minimize the heat-affected zone size. Typically, post-weld heat treatment is not required.
