HEAT TREATMENT
- When exceptional hardness, tensile strength, and fatigue strength are required, annealing can be performed at 1,700-1,900°F (927 - 1,038°C).
The DAXUN 6-4™ Grade 5 alloy can undergo a variety of heat treatments. - 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 is Rockwell C 30-34, while in the solution and aged condition it is about 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 for optimal properties.
- At room temperature, the Ti-6Al-4V, Grade 5 alloy bar is difficult to form, even when annealed. Therefore, severe forming operations such as bending or stretching should be performed on annealed material at temperatures up to 1,200°F; (649°C) without affecting mechanical properties. Hot sizing or forming can be achieved by 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 methods for austenitic stainless steel, with slow machining speeds, high feed rates, rigid tools, and the use of substantial amounts of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod exhibits excellent weldability in both its annealed and solution-plus-partially-aged conditions. Aging is executed during post-weld heat treatment. To avoid contamination from oxygen, nitrogen, and hydrogen, stringent precautions are essential. Fusion welding should occur in an inert gas-filled chamber or employ inert gas to protect the molten metal and adjacent heated zones, along with a tail shield. Additionally, spot, seam, and flash welding can be executed without the need for a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to contamination by hydrogen from improper pickling and by oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such contamination can lead to significant reductions in ductility, adversely affecting the material's 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 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 shown an extraordinary resistance to all forms of microbiologically influenced corrosion. While titanium alloys do not exhibit any toxicity towards marine organisms, biofouling can occur in seawater. This issue can be mitigated by chlorination or by increasing the water velocity through the heat exchanger.
Corrosion fatigue
Unlike many other materials, titanium does not experience a reduction 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
In the galvanic series, titanium is positioned towards the noble end near stainless steels and generally acts as the cathode when paired with other metals. As a result, titanium is not affected by galvanic corrosion but can accelerate the corrosion of the other metal. Pairing titanium with more noble metals, such as graphite, only enhances titanium's passivity.
Fatigue Properties
Grade 2 Titanium Rod stands out as it does not show degradation in fatigue properties when exposed to seawater. The fatigue endurance limits and *** growth rates remain the same whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod boasts excellent weldability, provided the necessary precautions are taken. Due to titanium's reactivity, an inert gas shield must be used on both the outer diameter (OD) and inner diameter (ID) of the rod. The material must also be free from any grease or oil contamination.
Grade 2 Titanium Rod is typically welded using manual or automatic TIG welding, with or without the use of filler wire. To minimize the size of the heat-affected zone, low heat input should be used. Titanium Rods are not usually subjected to post-weld heat treatment.
