ADVANCED HEAT TREATMENT
- For achieving high hardness, tensile strength, and fatigue strength, annealing can be carried out at 1,700-1,900°F (927 - 1,038°C).
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 delivers optimal properties. Larger sections and/or delayed quenching may yield suboptimal properties.
HARDNESS RANGE
Typical hardness in the annealed condition is Rockwell C 30-34, and about Rockwell C 35-39 in the solution treated and aged condition.
FORGEABILITY/FORMABILITY
- Ti-6Al-4V, Grade 5 alloy bars are forged at 1,750°F (954°C) with a final forging temperature of 1,450°F (788°C). A minimum 35% reduction is recommended for achieving optimal properties.
- The Ti-6Al-4V, Grade 5 alloy bar, known for its formidable strength and resilience, remains challenging to form at room temperature even when annealed. However, its malleability significantly improves at elevated temperatures, allowing severe forming operations like bending and stretching to be performed on annealed material at temperatures up to 1,200°F (649°C) without compromising mechanical properties. For hot sizing or forming, creep forming can be effectively utilized within the range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar offers excellent machinability when utilizing austenitic stainless steel machining methods. By employing slow machining speeds, high feeds, and rigid tools, and ensuring the abundant use of non-chlorinated cutting fluids, precision machining is achieved effortlessly.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is exceptionally weldable in both the annealed and partially aged conditions. Post-weld heat treatment facilitates aging. To ensure optimal weld integrity, it is essential to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding can be expertly performed in an inert gas-filled chamber or using inert gas to shield the molten metal and adjacent heated zones, along with a tail shield. Additionally, spot, seam, and flash welding can be performed without the need for a protective atmosphere.
Special Considerations
When handling Ti-6Al-4V, Grade 5 titanium alloy rods, it's crucial to avoid contamination with hydrogen during improper pickling, and with oxygen, nitrogen, and carbon during processes such as forging, heat treating, and brazing. Such contamination can lead to a loss of ductility, adversely affecting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion Resistance
Avoid using titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion
Table 1 showcases the general corrosion rates for Grade 2 titanium across various media. CP titanium boasts impressive corrosion resistance to a myriad of environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion
CP titanium provides excellent resistance to crevice corrosion in salt solutions compared to stainless steels. It shows no crevice corrosion at temperatures below 80°C (176°F), regardless of pH, even under highly chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium demonstrates superb resistance to stress corrosion cracking (SCC) in hot chloride solutions and remains immune to SCC in seawater.
Erosion Corrosion
Titanium exhibits outstanding resistance to erosion in flowing environments.
Our titanium rods are engineered to withstand seawater with velocities up to 130 ft/sec (40 m/sec), demonstrating negligible impact on the material. Even the presence of abrasive particles like sand has minimal effect on corrosion, ensuring lasting durability and performance in harsh marine environments.
Understanding Hydrogen Embrittlement
Titanium exhibits remarkable resistance to hydrogen absorption, especially when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only under specific conditions:
- 1. The pH is < 3 or > 12.
- 2. The temperature exceeds 176°F (80°C).
- 3. There is a mechanism for hydrogen generation, such as a galvanic couple or an impressed current.
Bio-corrosion Resistance
Titanium alloys showcase exceptional immunity to all forms of microbiologically influenced corrosion. While titanium alloys do not exhibit toxicity towards marine organisms, they can experience biofouling in seawater. This can be effectively managed through chlorination or by increasing water velocity in heat exchangers.
Corrosion Fatigue Performance
Unlike many other materials, titanium maintains its fatigue performance even in seawater. Fatigue endurance limits and fatigue *** growth rates remain consistent whether tested in air or seawater, ensuring reliable performance in demanding marine applications.
Galvanic Corrosion Resistance
Positioned towards the noble end of the galvanic series near stainless steels, titanium generally acts as the cathode when coupled with other metals. This means titanium itself is not affected by galvanic corrosion but can accelerate the corrosion of the other metal. When paired with more noble metals like graphite, titanium's passivity is further enhanced.
Fatigue Properties of Grade 2 Titanium
Grade 2 Titanium Rods do not experience a reduction in fatigue properties when exposed to seawater. Both fatigue endurance limits and fatigue *** growth rates are maintained whether in air or seawater, providing reliable durability under cyclical stress.
Weldability of CP2 Grade Titanium Rod
CP2 Grade Titanium Rods offer excellent weldability, provided proper precautions are followed. Due to titanium's reactivity, an inert gas shield must be applied to both the outer diameter (OD) and inner diameter (ID) of the rod. The material must also be free from grease or oil contamination before welding.
Typically, Grade 2 Titanium Rods are welded using manual or automatic TIG welding, with or without filler wire. Low heat input is recommended to minimize the heat-affected zone. Post-weld heat treatment is generally not necessary for titanium rods.
