HEAT TREATMENT
- For applications requiring high hardness, tensile strength, and fatigue strength, annealing can be performed at 1,700-1,900°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 optimum properties. However, larger section sizes and/or delayed quenching may result in less than optimal properties.
HARDNESS
Typical hardness in the annealed condition is Rockwell C 30-34, whereas, in the solution-treated and aged condition, it reaches Rockwell C 35-39.
Forgeability/Formability
- The Ti-6Al-4V, Grade 5 alloy bar is typically 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.
- Forming the Ti-6Al-4V, Grade 5 alloy bar at room temperature is challenging, even in the annealed state. Therefore, severe forming operations like bending or stretching should be performed on annealed materials at temperatures up to 1,200°F (649°C) without adversely affecting mechanical properties. Hot sizing or forming can be effectively carried out by creep forming in the range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar can be machined using methods suited for austenitic stainless steel. Slow machining speeds, high feeds, rigid tools, and copious amounts of non-chlorinated cutting fluids are recommended.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is impressively weldable whether in an annealed state or in a solution and partially aged condition, with aging occurring during a post-weld heat treatment. It is imperative to take precautions to avoid contamination by oxygen, nitrogen, and hydrogen. Fusion welding can be conducted in an inert gas-filled chamber or with an inert gas shielding the molten metal and its adjacent heated zones, utilizing a tail shield. Additionally, spot welding, seam welding, and flash welding can be executed without the necessity of a protective atmosphere.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rod runs the risk of hydrogen contamination due to improper pickling, as well as contamination by oxygen, nitrogen, and carbon during processes such as forging, heat treating, and brazing. Such contamination can lead to reduced ductility, negatively impacting both notch sensitivity and forming characteristics.

Grade 2 Titanium Rod Specifications
Outstanding Corrosion Resistance
Titanium is incompatible with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion Characteristics
Table 1 illustrates the general corrosion rates for Grade 2 titanium in various media. Commercially Pure (CP) titanium demonstrates exceptional corrosion resistance in diverse 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 resistance to crevice corrosion in salt solutions compared to stainless steels. It remains unaffected by crevice corrosion at temperatures below 80°C (176°F) irrespective of pH, even under superchlorinated conditions.
Stress Corrosion Cracking Resistance
Grade 2 titanium exhibits exceptional resistance to stress corrosion cracking (SCC) in hot chloride solutions and remains immune to SCC in seawater.
Erosion Corrosion Resistance
Titanium shows outstanding resistance to erosion in flowing
seawater at velocities up to 130 ft/sec (40 m/sec), with minimal impact on the material. The presence of abrasive particles, like sand, only slightly affects corrosion.
Hydrogen Embrittlement Resistance
Titanium does not significantly absorb hydrogen even when exposed to seawater at elevated temperatures. Hydrogen absorption typically occurs only when the following conditions align:
- pH levels are < 3 or > 12
- Temperature exceeds 176°F (80°C)
- A galvanic couple or an impressed current mechanism exists for hydrogen generation.
Bio-Corrosion Resistance
Titanium alloys exhibit unparalleled resistance to all forms of microbiologically influenced corrosion. Their non-toxicity towards marine organisms can lead to biofouling in seawater, which can be effectively minimized through chlorination or by boosting water velocity through the heat exchanger.
Corrosion Fatigue
Contrary to many other materials, titanium does not suffer a reduction in fatigue performance when exposed to seawater. Its fatigue endurance limits and fatigue *** growth rates remain consistent, whether tested in air or seawater.
Galvanic Corrosion
Positioned towards the noble end near stainless steels in the galvanic series, titanium typically acts as the cathode when paired with other metals. Consequently, titanium remains 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 stands out among materials by maintaining its fatigue properties in seawater. Its fatigue endurance limits and fatigue *** growth rates are consistent whether tested in air or seawater.
Weldability
The CP2 Grade Titanium Rod boasts excellent weldability, provided essential precautions are observed. Due to titanium's reactivity, an inert gas shield is required on both the OD and ID of the rod. The material must also be devoid of any grease or oil contaminants.
Grade 2 Titanium Rod is generally welded using manual or automatic TIG welding, with or without filler wire. To minimize the heat-affected zone, low heat input should be used. Post-weld heat treatment is typically unnecessary for Titanium Rod.
