HEAT TREATMENT
- For requirements of high hardness, tensile strength, and fatigue strength, annealing can be conducted at 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy offers diverse 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 state, rapid quenching of smaller sections achieves optimal properties. Larger section sizes or delayed quenching may yield less optimal properties.
HARDNESS
Typical hardness in the annealed state ranges from Rockwell C 30-34, while in the solution-treated and aged condition, it ranges around 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). A minimum reduction of 35% is recommended to achieve optimal properties.
- Forming Ti-6Al-4V, Grade 5 alloy bar at room temperature is challenging, even in the annealed state. Severe forming operations like bending or stretching can be performed on annealed material at temperatures up to 1,200°F; (649°C) without compromising mechanical properties. Hot forming can be executed by creep forming within the temperature 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, utilizing slow machining speeds, high feeds, rigid tools, and abundant use of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod features exceptional weldability, whether in its annealed state or in its solution and partially aged condition. Aging is achieved during post-weld heat treatment. To maintain its integrity, it is crucial to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding is optimally performed in an inert gas-filled chamber, or with inert gas shielding the molten metal and adjacent heated zones, complete with a tail shield. Spot, seam, and flash welding can be executed without the necessity of a protective atmosphere.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rods must be handled delicately to avoid contamination. Exposure to hydrogen during improper pickling, or to oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing, can compromise ductility. Such contamination can adversely impact notch sensitivity and forming characteristics, potentially reducing the material's effectiveness.

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 a variety of media are shown in Table 1. CP titanium exhibits good corrosion resistance to a wide variety of environments including:
- Seawater and brines
- Inorganic salts
- Moist *** gas
- Alkaline solutions
- Oxidizing acids
- Organics and organic acids
- Sulfur compounds
Crevice corrosion
CP titanium exhibits good resistance to crevice corrosion in salt solutions compared to stainless steels. CP titanium will not exhibit crevice corrosion at temperatures under 80 °C ( 176°F) regardless of pH, even under super chlorinated conditions.
Stress corrosion cracking
Grade 2 titanium shows excellent resistance to stress corrosion (SCC) cracking in hot chloride solutions and is immune to sec in seawater.
Erosion corrosion
Titanium shows excellent resistance to erosion in flowing
seawater with velocities up to 130 ft/sec ( 40 m/sec) showing negligible effect on the material. The presence of abrasive particles, such as sand, has only a small effect on corrosion.
Hydrogen embrittlement
There is no significant absorption of hydrogen into titanium exposed to seawater, even at higher temperatures. Normally hydrogen absorption occurs only when the three following conditions are met:
- pH is < 3 or > 12
- Temperature is above l 76F (80C)
- A mechanism exists for hydrogen generation such as a galvanic couple or impressed current.
Bio-corrosion
Titanium alloys are renowned for their exceptional resistance to microbiologically influenced corrosion. Unlike many other materials, titanium alloys exhibit no toxicity to marine organisms, though biofouling can still occur in seawater environments. This issue can be effectively mitigated through chlorination or by enhancing the water velocity within the heat exchanger.
Corrosion Fatigue
Titanium stands out from other materials as it maintains its fatigue performance even in seawater. Whether tested in air or seawater, the fatigue endurance limits and fatigue *** growth rates remain consistent.
Galvanic Corrosion
Positioned at the noble end of the galvanic series, near stainless steels, titanium typically serves as the cathode when paired with other metals. This means titanium itself is immune to galvanic corrosion, although it may accelerate the corrosion of the coupled metal. When titanium is paired with noble metals like graphite, its passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod is exceptional in that it does not experience degradation in fatigue properties in seawater. The fatigue endurance limits and fatigue *** growth rates are identical whether the material is tested in air or seawater.
Weldability
CP2 Grade Titanium Rod boasts excellent weldability, provided the necessary precautions are observed. Due to titanium's reactivity, an inert gas shield must be used on both the outer and inner diameters of the rod. Ensuring the material is free from grease or oil contamination is also crucial.
Grade 2 Titanium Rod can be 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 generally not required for Titanium Rod.
