HEAT TREATMENT
- For applications requiring high hardness, tensile strength, and fatigue strength, annealing can be performed at temperatures between 1,700-1,900°F (927 - 1,038°C).
The DAXUN 6-4™ Grade 5 alloy can be subjected to various heat treatment methods to achieve desired properties. - 1. Anneal: 1,275 -1,400°F; (691 - 760°C) for ½ to 2 hours, followed by air or furnace cooling.
- 2. Stress Relief Anneal: 1,000 -1,200°F; (538 - 649°C) for 1 to 8 hours, followed by air or furnace cooling.
- 3. Solution Heat Treat: 1,675 -1,750°F; (913 - 954°C) for 1 hour, followed by water quenching.
- 4. Aging: 975 -1,025°F; (524 - 552°C) for 4 to 8 hours, followed by air cooling.
In the solution treated and aged condition, rapid quenching of smaller sections yields optimum mechanical properties. For larger section sizes and/or delayed quenching, properties may be less than optimal.
HARDNESS
The typical hardness in the annealed condition is Rockwell C 30-34, while in the solution and aged condition, it ranges from Rockwell C 35-39.
Forgeability/Formability
- Ti-6Al-4V, Grade 5 alloy bars are 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 optimum mechanical properties.
- Ti-6Al-4V, Grade 5 alloy bars are difficult to form at room temperature, even in the annealed condition. Severe forming operations such as bending or stretching should be performed on annealed material at temperatures up to 1,200°F (649°C) to avoid affecting mechanical properties. Hot sizing or forming can be achieved through creep forming between 1,000 - 1,200°F (538 - 649°C).
Machinability
Ti-6Al-4V, Grade 5 alloy bars can be machined using methods suitable for austenitic stainless steel, with slow machining speeds, high feeds, rigid tools, and the application of large amounts of non-chlorinated cutting fluids.
Weldability
Elevate your welding projects with the Ti-6Al-4V, Grade 5 alloy rod! This rod is effortlessly weldable in both annealed and solution/partially aged conditions, with aging achieved during post-weld heat treatment. To maintain the rod's integrity, it is crucial to protect it from contamination by oxygen, nitrogen, and hydrogen. For optimal results, fusion welding should take place in an inert gas-filled chamber or with inert gas shielding the molten metal and adjacent heated zones, employing a tail shield. Additionally, spot, seam, and flash welding can be executed without the necessity of a protective atmosphere.
Special Considerations
When working with Ti-6Al-4V, Grade 5 titanium alloy rods, it is important to note the possibility of contamination. Improper pickling can lead to hydrogen contamination, while oxygen, nitrogen, and carbon contamination can occur during processes like forging, heat treating, and brazing. This contamination can diminish ductility, negatively impacting notch sensitivity and forming characteristics.

Premium Grade 2 Titanium Rod
Superior Corrosion Resistance
Avoid using titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion Resistance
Table 1 details the general corrosion rates for Grade 2 titanium across various media. CP titanium boasts robust corrosion resistance in diverse environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organic Compounds and Organic Acids
- Sulfur Compounds
Outstanding Crevice Corrosion Resistance
CP titanium offers excellent resistance to crevice corrosion in salt solutions, outperforming stainless steels. CP titanium remains unaffected by crevice corrosion at temperatures below 80°C (176°F) regardless of pH, even under highly chlorinated conditions.
Resilient Stress Corrosion Cracking
Grade 2 titanium exhibits superior resistance to stress corrosion cracking (SCC) in hot chloride solutions and is completely immune to SCC in seawater.
Erosion Corrosion Resistance
Titanium demonstrates remarkable resistance to erosion in flowing
seawater at velocities up to 130 ft/sec (40 m/sec) with negligible impact on the material. Even with abrasive particles like sand, corrosion effects remain minimal.
Hydrogen Embrittlement Resistance
Titanium in seawater exhibits negligible hydrogen absorption, even at elevated temperatures. Hydrogen absorption occurs only under these conditions:
- pH levels below 3 or above 12
- Temperatures exceeding 176°F (80°C)
- Presence of a hydrogen generation mechanism, such as a galvanic couple or impressed current.
Bio-Corrosion Resistance
Titanium alloys showcase an extraordinary resistance to all forms of microbiologically influenced corrosion. As these alloys are non-toxic to marine organisms, biofouling can occur in seawater environments. This issue can be effectively mitigated by chlorination or by enhancing the water velocity through the heat exchanger.
Corrosion Fatigue
Titanium is unique in that it maintains its fatigue performance even in the presence of seawater. Both the fatigue endurance limits and the fatigue *** growth rates remain consistent whether tested in air or seawater, ensuring reliable performance in marine applications.
Galvanic Corrosion
In the galvanic series, titanium is positioned near the noble end alongside stainless steels, typically acting as the cathode when paired with other metals. Consequently, titanium remains unaffected by galvanic corrosion but may 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 exhibits resilience in fatigue properties, even in seawater. The fatigue endurance limits and fatigue *** growth rates are unchanged whether tested in air or seawater, making it an excellent choice for marine applications.
Weldability
CP2 Grade Titanium Rod is highly weldable with the right precautions. Due to titanium's reactivity, an inert gas shield must cover both the OD and ID of the rod. The material must also be free from grease or oil contamination to ensure quality welds.
Grade 2 Titanium Rods are typically welded using manual or automatic TIG welding techniques, with or without filler wire. To minimize the size of the heat-affected zone, low heat input is recommended. Post-weld heat treatment is generally not required for Titanium Rods.
