HEAT TREATMENT
- For applications demanding high hardness, tensile strength, and fatigue strength, annealing can be performed at 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy offers versatility in heat treatment methods. - 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 optimal properties. Larger section sizes and/or delayed quenching may result in less than optimal properties.
HARDNESS
Typical hardness in the annealed condition ranges from Rockwell C 30-34, while in the solution treated and aged condition it ranges from Rockwell C 35-39.
Forgeability/Formability
- Ti-6Al-4V, Grade 5 alloy rods are 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 rods at room temperature, even in the annealed condition, is challenging. For severe forming operations such as bending or stretching, annealed material can be processed at temperatures up to 1,200°F; (649°C) without compromising mechanical properties. Hot sizing or forming is achieved through creep forming within the range of 1,000 - 1,200°F; (538 - 649°C).
Machinability
Ti-6Al-4V, Grade 5 alloy rods can be machined using techniques similar to those for austenitic stainless steel, involving slow machining speeds, high feeds, rigid tools, and abundant use of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is highly weldable in its annealed state or when solution treated and partially aged, with aging taking place during post-weld heat treatment. It is crucial to avoid contamination from oxygen, nitrogen, and hydrogen. Fusion welding should be conducted in an inert gas-filled chamber or with inert gas shielding both the molten metal and adjacent heated zones, complemented by a tail shield. Additionally, spot, seam, and flash welding can be executed without a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod can absorb hydrogen during improper pickling and oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. This contamination can reduce ductility, impacting notch sensitivity and forming properties.

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 have exhibited an exceptional resistance to all forms of microbiologically influenced corrosion. Due to their non-toxic nature towards marine life, biofouling can occur in seawater but can be controlled through chlorination or by increasing water velocity through heat exchangers.
Corrosion Fatigue
Titanium stands out among materials as it does not suffer a decrease in fatigue performance when exposed to seawater. The fatigue endurance limits and fatigue *** growth rates remain consistent, whether tested in air or seawater.
Galvanic Corrosion
Positioned towards the noble end of the galvanic series, near stainless steels, titanium usually 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. Pairing titanium with more noble metals, such as graphite, further enhances its passivity.
Fatigue Properties
Unlike many materials, Grade 2 Titanium Rod maintains its fatigue properties even in seawater. The fatigue endurance limits and *** growth rates are consistent in both air and seawater tests.
Weldability
CP2 Grade Titanium Rod is highly weldable, provided specific precautions are taken. Due to titanium's reactivity, an inert gas shield must be applied to both the OD and ID of the rod. The material must also 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. It is crucial to use low heat input to minimize the heat-affected zone. Post-weld heat treatment is usually not necessary.
