HEAT TREATMENT
- For applications requiring 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).
DAXUN 6-4™ Grade 5 alloy is versatile in 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, followed by water quenching
- 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 smaller sections yields optimal properties. However, larger sections or delayed quenching may result in suboptimal properties.
HARDNESS
Typically, hardness in the annealed condition measures Rockwell C 30-34. In the solution-treated and aged condition, it reaches approximately Rockwell C 35-39.
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). For optimal properties, a minimum reduction of 35% is recommended.
- The Ti-6Al-4V, Grade 5 alloy bar is known for its challenging formability at room temperature, even when annealed. To achieve severe forming operations like bending or stretching, annealed material can be heated up to 1,200°F (649°C) without compromising its mechanical properties. For hot sizing or forming, consider creep forming within the range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar can be machined using techniques similar to those for austenitic stainless steel. Employ slow machining speeds, high feed rates, rigid tools, and copious amounts of non-chlorinated cutting fluids for optimal results.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod offers excellent weldability in both annealed and solution/partially aged conditions, with aging achievable during post-weld heat treatment. It's crucial to avoid contamination with oxygen, nitrogen, and hydrogen. Fusion welding is best performed in an inert gas-filled chamber or using inert gas to shield the molten metal and heated zones. Spot, seam, and flash welding can be executed without a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to contamination from hydrogen due to improper pickling, and from oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such contamination can lead to reduced 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. Commercially Pure (CP) titanium offers excellent corrosion resistance across a wide range of environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion
CP titanium shows good resistance to crevice corrosion in salt solutions compared to stainless steels. CP titanium does not exhibit crevice corrosion at temperatures below 80°C (176°F), regardless of pH, even in super-chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium exhibits excellent resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion
Titanium demonstrates outstanding resistance to erosion in flowing conditions.
Seawater with velocities up to 130 ft/sec (40 m/sec) shows negligible effects on this exceptional material. Even in the presence of abrasive particles, such as sand, the corrosion impact remains minimal.
Hydrogen Embrittlement
Titanium exhibits no significant absorption of hydrogen when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically only occurs when the following three conditions are met:
- 1. pH level is less than 3 or greater than 12.
- 2. Temperature exceeds 176°F (80°C).
- 3. A mechanism exists for hydrogen generation, such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys showcase a unique immunity to all forms of microbiologically influenced corrosion. Despite titanium's non-toxicity towards marine organisms leading to potential biofouling in seawater, this can be minimized through chlorination or by increasing water velocity through the heat exchanger.
Corrosion Fatigue
Unlike many other materials, titanium exhibits consistent fatigue performance in the presence of seawater. Fatigue endurance limits and fatigue *** growth rates remain the same whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is positioned towards the noble end, near stainless steels, and typically acts as the cathode when coupled 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, such as graphite, titanium's passivity is enhanced.
Fatigue Properties
Grade 2 Titanium Rod maintains its fatigue properties even in the presence of seawater. Fatigue endurance limits and fatigue *** growth rates are identical whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod offers excellent weldability when proper precautions are observed. Given 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 Rod is typically welded using manual or automatic TIG welding, with or without filler wire. Low heat input is recommended to minimize the heat-affected zone size. Post-weld heat treatment is generally not required.
