ADVANCED HEAT TREATMENT
- For applications demanding high hardness, tensile strength, and fatigue strength, annealing is performed at temperatures ranging from 1,700-1,900°F (927 - 1,038°C).
The DAXUN 6-4™ Grade 5 alloy offers versatile heat treatment options. - 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 optimal properties, while larger sections or delayed quenching may result in reduced performance.
HARDNESS CHARACTERISTICS
Typical hardness in the annealed condition ranges from Rockwell C 30-34, and in the solution treated and aged condition, it ranges from Rockwell C 35-39.
Forgeability & Formability
- The Ti-6Al-4V, Grade 5 alloy bar is optimally 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 superior properties.
- The Ti-6Al-4V, Grade 5 alloy bar, known for its challenging formability at room temperature, even when annealed, requires special handling. For severe forming tasks like bending or stretching, annealed material can be worked at temperatures up to 1,200°F (649°C) without compromising mechanical properties. Hot sizing or forming is efficiently achieved through creep forming within the 1,000 - 1,200°F (538 - 649°C) range.
Machinability
Employing traditional austenitic stainless steel machining methods, the Ti-6Al-4V, Grade 5 alloy bar can be effectively machined. Slow machining speeds, high feeds, rigid tool setups, and generous use of non-chlorinated cutting fluids are recommended to ensure optimal results.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod excels in weldability whether in the annealed state or when solution-treated and partially aged, with aging processes completed during post-weld heat treatment. To prevent contamination, avoid exposure to oxygen, nitrogen, and hydrogen. Fusion welding should be performed in an inert gas environment, ensuring coverage of molten metal and adjacent zones. Spot, seam, and flash welding can be executed without a protective atmosphere.
Special Considerations
Attention must be given to the Ti-6Al-4V, Grade 5 titanium alloy rod to avoid contamination from hydrogen during improper pickling, and from oxygen, nitrogen, and carbon during processes like forging and heat treating. Such contamination risks reducing ductility, which can negatively impact notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion Resistance
Titanium should not be exposed to 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 offers excellent resistance to a broad 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 demonstrates superior resistance to crevice corrosion in salt solutions compared to stainless steels. It will not exhibit crevice corrosion at temperatures below 80°C (176°F), regardless of pH, even in super-chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium offers outstanding resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion
Titanium boasts excellent resistance to erosion in flowing environments.
The material displays exceptional resilience, with seawater velocities reaching up to 130 ft/sec (40 m/sec) showing negligible impact. Even the presence of abrasive particles like sand only slightly affects its corrosion resistance.
Hydrogen Embrittlement
Titanium exhibits minimal hydrogen absorption when exposed to seawater, even at elevated temperatures. Typically, hydrogen absorption only occurs when the following three conditions are met:
- pH is < 3 or > 12
- Temperature exceeds 176°F (80°C)
- A mechanism exists for hydrogen generation, such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys showcase a remarkable immunity to all forms of microbiologically influenced corrosion. Since these alloys are non-toxic to marine organisms, biofouling in seawater can occur. This can be mitigated by chlorination or by increasing water velocity through the heat exchanger.
Corrosion Fatigue
Titanium stands out among materials by maintaining its fatigue performance in seawater. Both fatigue endurance limits and fatigue *** growth rates remain consistent whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is positioned near the noble end, close to stainless steels, usually acting as the cathode when paired with other metals. This means titanium is not affected by galvanic corrosion but can accelerate the corrosion of the other metal. Coupling titanium with more noble metals, such as graphite, enhances titanium's passivity.
Fatigue Properties
Grade 2 Titanium Rod is unique in that it does not experience degradation in fatigue properties in seawater. Its fatigue endurance limits and fatigue *** growth rates are consistent whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable with proper precautions. Due to titanium's reactivity, an inert gas shield must be used on both the OD and ID of the rod. The material must be free of any grease or oil contamination.
Grade 2 Titanium Rod is typically welded using manual or automatic TIG welding, with or without filler wire. Low heat input should be used to minimize the heat-affected zone. Post-weld heat treatment is generally not required for Titanium Rod.
