HEAT TREATMENT
- For applications requiring high hardness, tensile strength, and fatigue strength, annealing can be performed at 1,700-1,900°F (927 - 1,038°C).
Our DAXUN 6-4™ Grade 5 alloy can be heat treated in a variety of ways to meet specific requirements. - 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 section sizes and/or delayed quenching may result in less than optimum properties.
HARDNESS
Typical hardness in the annealed condition is Rockwell C 30-34, and about Rockwell C 35-39 in the solution and aged condition.
Forgeability/Formability
- Ti-6Al-4V, Grade 5 alloy bar is ideally forged at 1,750°F (954°C) with a final forging temperature of 1,450°F (788°C). A minimum of 35% reduction is recommended to achieve the best properties.
- Ti-6Al-4V, Grade 5 alloy bar is challenging to form at room temperature, even in the annealed condition. 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 accomplished by creep forming in the range of 1,000 - 1,200°F (538 - 649°C).
Machinability
Ti-6Al-4V, Grade 5 alloy bar can be machined using austenitic stainless steel machining methods, incorporating slow machining speeds, high feed rates, rigid tools, and ample non-chlorinated cutting fluids.
Weldability
Ti-6Al-4V, Grade 5 alloy rod is highly weldable in both the annealed and solution-treated conditions, with post-weld heat treatment offering optimal aging benefits. It's crucial to protect the material from contamination by oxygen, nitrogen, and hydrogen. Fusion welding should be conducted in an inert gas-filled chamber or with inert gas shielding for the molten metal and adjacent heated zones. Additional welding methods like spot, seam, and flash welding can also be performed without a protective atmosphere.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rod can suffer contamination from hydrogen during improper pickling, as well as from oxygen, nitrogen, and carbon during processes such as forging, heat treating, and brazing. Such contamination may lead to reduced ductility, adversely impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Exceptional Corrosion Resistance
Titanium is not suitable for use with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion
Grade 2 titanium boasts impressive general corrosion rates across various media, as demonstrated in Table 1. CP titanium exhibits robust resistance to a diverse array 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 excellent resistance to crevice corrosion in salt solutions compared to stainless steels. It remains resistant at temperatures under 80°C (176°F), irrespective of pH, even in highly chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium effectively resists stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion
Titanium displays outstanding resistance to erosion in moving
seawater at velocities up to 130 ft/sec (40 m/sec), exhibiting minimal impact on the material. Even with the presence of abrasive particles like sand, corrosion is only slightly affected.
Hydrogen Embrittlement
Titanium shows negligible hydrogen absorption in seawater, even at elevated temperatures. Significant hydrogen absorption occurs only under these conditions:
- pH levels below 3 or above 12
- Temperatures exceeding 176°F (80°C)
- Presence of a hydrogen generation mechanism such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys exhibit exceptional resistance to all forms of microbiologically influenced corrosion. Their non-toxic nature towards marine organisms can sometimes lead to biofouling in seawater. However, this can be effectively minimized through chlorination or increased water velocity in the heat exchanger.
Corrosion Fatigue
Unlike many other materials, titanium maintains its fatigue performance even in the presence of seawater. Fatigue endurance limits and *** growth rates are consistent whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is positioned near the noble end, close to stainless steels, and typically acts as the cathode when paired with other metals. This means titanium remains unaffected by galvanic corrosion but can accelerate the corrosion of the other metal. Coupling titanium with more noble metals like graphite further enhances its passivity.
Fatigue Properties
Grade 2 Titanium Rod stands out for its consistent fatigue properties, even in seawater environments. Fatigue endurance limits and *** growth rates show no degradation whether in air or seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable when proper precautions are observed. Due to titanium's reactivity, an inert gas shield must be applied to both the OD and ID of the rod, and the material must be free from any grease or oil contamination.
Grade 2 Titanium Rod is commonly welded using manual or automatic TIG welding, with or without filler wire. Low heat input is recommended to minimize the heat-affected zone, and post-weld heat treatment is typically unnecessary.
