HEAT TREATMENT
- For high hardness, tensile strength, and fatigue strength, annealing at temperatures of 1,700-1,900°F (927 - 1,038°C) is recommended.
Our DAXUN 6-4™ Grade 5 alloy offers versatile 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 condition, rapid quenching of small sections yields optimum properties. Larger sections and/or delayed quenching may result in less than optimal properties.
HARDNESS
Typical hardness in the annealed condition ranges from Rockwell C 30-34, and in the solution and aged condition, it ranges from Rockwell C 35-39.
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). For optimum properties, a minimum reduction of 35% is recommended.
- Forming Ti-6Al-4V, Grade 5 alloy bar at room temperature is challenging, 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 compromising 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
Ti-6Al-4V, Grade 5 alloy bar can be machined using methods for austenitic stainless steel, employing slow speeds, high feeds, rigid tools, and generous amounts of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 titanium alloy rod is renowned for its exceptional weldability, whether in the annealed state or in the solution and partially aged condition. Aging can be efficiently performed during post-weld heat treatment. To maintain its integrity, it's crucial to safeguard against contamination by oxygen, nitrogen, and hydrogen. Fusion welding should ideally be carried out in an inert gas-filled chamber, or at the very least, with inert gas shielding the molten metal and adjacent heated zones, complemented by a tail shield. Techniques such as spot, seam, and flash welding are feasible without a protective atmosphere, ensuring versatility in applications.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to hydrogen contamination from improper pickling, as well as oxygen, nitrogen, and carbon contamination during processes like forging, heat treating, and brazing. Such contamination can lead to a significant reduction in ductility, negatively impacting notch sensitivity and forming characteristics. Therefore, stringent process controls are essential to preserve the material's premium properties.

Grade 2 Titanium Rod
Corrosion resistance
Titanium is unsuitable for use with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General corrosion
The general corrosion rates for Grade 2 titanium in various media are detailed in Table 1. CP titanium demonstrates excellent corrosion resistance across a diverse range of environments, including:
- Seawater and brines
- Inorganic salts
- Moist *** gas
- Alkaline solutions
- Oxidizing acids
- Organics and organic acids
- Sulfur compounds
Crevice corrosion
CP titanium offers superior resistance to crevice corrosion in salt solutions compared to stainless steels. It does not exhibit crevice corrosion at temperatures below 80°C (176°F), regardless of pH, even in highly chlorinated conditions.
Stress corrosion cracking
Grade 2 titanium provides outstanding resistance to stress corrosion cracking (SCC) in hot chloride solutions and remains immune to SCC in seawater.
Erosion corrosion
Titanium exhibits excellent resistance to erosion in flowing seawater at velocities up to 130 ft/sec (40 m/sec), with minimal impact on the material. The presence of abrasive particles, like sand, has only a slight effect on corrosion.
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
Titanium shows no significant hydrogen absorption when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only if the following conditions are met:
- pH is < 3 or > 12
- Temperature exceeds 176°F (80°C)
- A mechanism for hydrogen generation exists, such as a galvanic couple or impressed current.
Bio-corrosion
Titanium alloys possess an extraordinary resistance to all types of microbiologically influenced corrosion. These alloys are non-toxic to marine organisms, which may lead to biofouling in seawater. This can be effectively mitigated by chlorination or by increasing the velocity of water through the heat exchanger.
Corrosion fatigue
Titanium stands out among materials for its unchanged fatigue performance in the presence of seawater. Fatigue endurance limits and fatigue *** growth rates remain consistent whether tested in air or seawater environments.
Galvanic corrosion
Positioned near the noble end of the galvanic series alongside stainless steels, titanium typically acts as the cathode when paired with other metals. This ensures that titanium itself is not affected by galvanic corrosion, although it can accelerate corrosion of the connected metal. When coupled with more noble metals, like graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod exhibits steadfast fatigue properties even in seawater. Its fatigue endurance limits and fatigue *** growth rates are uniform whether evaluated in air or seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable with the proper precautions. Given titanium's reactivity, an inert gas shield must protect both the outer and inner surfaces of the rod. It is essential to ensure the material is devoid of any grease or oil contamination.
Typically, Grade 2 Titanium Rods are welded using manual or automatic TIG welding, with or without filler wire. Employing low heat input helps minimize the heat-affected zone. Post-weld heat treatment is generally not required for Titanium Rod.
