HEAT TREATMENT
- For applications demanding high hardness, tensile strength, and fatigue strength, annealing can be executed between 1,700-1,900°F (927 - 1,038°C).
Our DAXUN 6-4™ Grade 5 alloy offers versatile heat treatment options tailored to your needs. - 1. Anneal: 1,275 - 1,400°F (691 - 760°C), hold for ½ to 2 hours, then air or furnace cool
- 2. Stress Relief Anneal: 1,000 - 1,200°F (538 - 649°C), hold for 1 to 8 hours, then air or furnace cool
- 3. Solution Heat Treat: 1,675 - 1,750°F (913 - 954°C), hold for 1 hour, then water quench
- 4. Aging: 975 - 1,025°F (524 - 552°C), hold for 4 to 8 hours, then air cool
In the solution treated and aged condition, quick quenching of smaller sections yields optimal properties. Larger sections or delayed quenching may result in less than optimal properties.
HARDNESS
Typical hardness in the annealed state is Rockwell C 30-34, and approximately Rockwell C 35-39 in the solution treated and aged condition.
Forgeability/Formability
- 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 of 35% reduction is recommended to achieve optimal properties.
- Ti-6Al-4V, Grade 5 alloy bar presents challenges when forming at room temperature, even when annealed. Thus, intense forming operations like bending or stretching can be done on annealed material at temperatures up to 1,200°F (649°C) without impacting mechanical properties. Hot sizing or forming can be performed via creep forming within the range of 1,000 - 1,200°F (538 - 649°C).
Machinability
Machining Ti-6Al-4V, Grade 5 alloy bar can be achieved using austenitic stainless steel techniques, employing slow machining speeds, high feed rates, rigid tooling, and abundant non-chlorinated cutting fluids.
Weldability
Ti-6Al-4V, Grade 5 alloy rod is effortlessly weldable in either annealed or solution and partially aged conditions, with aging achieved during post-weld heat treatment. To maintain pristine quality, precautions are necessary to prevent contamination from oxygen, nitrogen, and hydrogen. For fusion welding, utilize an inert gas-filled chamber or inert gas along with a tail shield to weld the molten metal and adjacent heated zones. Additionally, spot, seam, and flash welding can be executed without needing a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to contamination. Hydrogen contamination can occur from improper pickling, while oxygen, nitrogen, and carbon contamination may happen during forging, heat treating, and brazing processes. Such contamination can reduce ductility, potentially affecting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Exceptional Corrosion Resistance
Avoid using titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion Data
As illustrated in Table 1, Grade 2 titanium demonstrates excellent corrosion resistance across various media. Commercially pure (CP) titanium is highly resistant to multiple environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organic Compounds and Acids
- Sulfur Compounds
Resistance to Crevice Corrosion
CP titanium excels in resisting crevice corrosion in salt solutions, outperforming stainless steels. It remains unscathed by crevice corrosion at temperatures below 80°C (176°F) regardless of pH, even under hyper-chlorinated conditions.
Stress Corrosion Cracking Resistance
Grade 2 titanium offers outstanding resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Excellent Erosion Corrosion Resistance
Titanium boasts superb resistance to erosion in fast-flowing
seawater with velocities reaching up to 130 ft/sec (40 m/sec), resulting in negligible impact on the material. The presence of abrasive elements like sand minimally affects corrosion.
Hydrogen Embrittlement Resistance
No significant hydrogen absorption occurs in titanium exposed to seawater, even at elevated temperatures. Hydrogen absorption is typically noted only when three conditions coexist:
- pH levels are < 3 or > 12
- Temperatures exceed 176°F (80°C)
- A mechanism for hydrogen generation, such as a galvanic couple or impressed current, is present.
Bio-corrosion
Titanium alloys exhibit an exceptional resistance to all forms of microbiologically influenced corrosion. Notably, they show no toxicity towards marine organisms, allowing biofouling in seawater. This can be mitigated through chlorination or by increasing water velocity in heat exchangers.
Corrosion fatigue
Unlike many other materials, titanium maintains its fatigue performance even in seawater. Fatigue endurance limits and *** growth rates are consistent in both air and seawater environments.
Galvanic corrosion
Titanium, positioned near the noble end of the galvanic series close to stainless steels, usually acts as the cathode when paired with other metals. Consequently, titanium remains unaffected by galvanic corrosion but may accelerate the corrosion of the coupled metal. Pairing titanium with more noble metals, like graphite, further enhances its passivity.
Fatigue Properties
Grade 2 Titanium Rod retains its fatigue properties even in seawater, unlike many other materials. Its fatigue endurance limits and *** growth rates remain the same whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod boasts excellent weldability when proper precautions are taken. Due to titanium's reactivity, an inert gas shield is required on both the OD and ID of the rod, and the material must be free of grease or oil contamination.
Grade 2 Titanium Rod is often welded using manual or automatic TIG welding, with or without filler wire. To minimize the heat-affected zone, low heat input is recommended. Post-weld heat treatment is typically unnecessary.
