HEAT TREATMENT
- For applications requiring high hardness, tensile strength, and fatigue strength, annealing can be performed at temperatures between 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy offers versatile heat treatment options to suit your specific needs. - 1. Anneal: Perform at 1,275 -1,400°F; (691 - 760°C) for ½ to 2 hours followed by air or furnace cooling.
- 2. Stress Relief Anneal: Perform at 1,000 -1,200°F; (538 - 649°C) for 1 to 8 hours followed by air or furnace cooling.
- 3. Solution Heat Treat: Perform at 1,675 -1,750°F; (913 - 954°C) for 1 hour followed by water quenching.
- 4. Aging: Perform at 975 -1,025°F; (524 - 552°C) for 4 to 8 hours followed by air cooling.
Rapid quenching of small sections in the solution treated and aged condition yields optimum properties. However, larger section sizes and/or delayed quenching might result in less than optimum properties.
HARDNESS
In the annealed condition, the typical hardness ranges between Rockwell C 30-34, while in the solution and aged condition, it ranges between Rockwell C 35-39.
Forgeability/Formability
- Ti-6Al-4V, Grade 5 alloy bar should be forged at 1,750°F; (954°C) with a final forging temperature of 1,450°F; (788°C). For optimum properties, a minimum of 35% reduction is recommended.
- Due to its difficulty to form at room temperature, severe forming operations like bending or stretching on Ti-6Al-4V, Grade 5 alloy bar should be performed on annealed material at temperatures up to 1,200°F; (649°C) to avoid affecting mechanical properties. Hot sizing or forming can be achieved 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 methods suitable for austenitic stainless steel. Slow machining speeds, high feed rates, rigid tools, and the use of large amounts of non-chlorinated cutting fluids are recommended for optimal results.
Weldability
The Ti-6Al-4V (Grade 5) alloy rod offers outstanding weldability in both the annealed and solution-partially-aged conditions, with aging completed during post-weld heat treatment. Careful measures are required to avoid contamination from oxygen, nitrogen, and hydrogen. Fusion welding should be performed in an inert gas-filled chamber, or with inert gas shields for the molten metal and adjacent heated areas, offering optimal protection. Spot, seam, and flash welding can be executed without the need for protective atmospheres.
Special Considerations
Grade 5 Ti-6Al-4V titanium alloy rods are susceptible to contamination from hydrogen during improper pickling and from oxygen, nitrogen, and carbon during forging, heat treating, and brazing processes. Such contamination can lead to reduced ductility, negatively impacting notch sensitivity and forming properties.

Grade 2 Titanium Rod
Corrosion Resistance
Titanium should not be used with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous *** to prevent degradation.
General Corrosion
The general corrosion rates for Grade 2 titanium are impressive across various media. CP titanium offers robust resistance in a multitude of environments, including:
- Seawater and brines, ensuring durability in marine environments.
- Inorganic salts, providing resilience in chemical processing.
- Moist *** gas, ensuring safety in industrial applications.
- Alkaline solutions, enhancing longevity in caustic environments.
- Oxidizing acids, offering reliability in harsh chemical settings.
- Organics and organic acids, ensuring stability in diverse organic environments.
- Sulfur compounds, maintaining integrity in sulfur-rich conditions.
Crevice Corrosion
CP titanium demonstrates superior resistance to crevice corrosion in salt solutions compared to stainless steels, remaining unaffected at temperatures below 80°C (176°F) regardless of pH, even in highly chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium excels in resisting 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
seawater at velocities up to 130 ft/sec (40 m/sec), showing negligible impact on the material. Even abrasive particles like sand have minimal effect on corrosion.
Hydrogen Embrittlement
Titanium shows minimal hydrogen absorption in seawater, even at elevated temperatures. Hydrogen absorption typically occurs only under the following conditions:
- pH is < 3 or > 12, creating an acidic or highly alkaline environment.
- Temperature exceeds 176°F (80°C), increasing reactivity.
- A galvanic couple or impressed current is present, facilitating hydrogen generation.
Bio-corrosion
Titanium alloys exhibit an unparalleled resistance to microbiologically influenced corrosion. These alloys, being nontoxic to marine organisms, may experience biofouling in seawater, which can be effectively controlled by chlorination or increasing water flow rates through heat exchangers.
Corrosion fatigue
Titanium stands out from many other materials due to its unchanged fatigue performance in seawater. The fatigue endurance limits and *** growth rates remain consistent regardless of being tested in air or seawater.
Galvanic corrosion
Positioned towards the noble end of the galvanic series near stainless steels, titanium typically functions as the cathode when paired with other metals. This means titanium itself remains unaffected by galvanic corrosion, though it may expedite the corrosion of coupled metals. When paired with more noble metals like graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod maintains its exceptional fatigue properties even in seawater, showing no signs of degradation. Fatigue endurance limits and *** growth rates remain the same whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod boasts excellent weldability when the proper precautions are adhered to. Given titanium's reactivity, it requires an inert gas shield on both its outer and inner surfaces. The material must be devoid of any grease or oil contamination.
Grade 2 Titanium Rod is primarily welded using manual or automatic TIG welding, with or without filler wire. It's important to use low heat input to minimize the heat affected zone size. Post weld heat treatment is generally not needed for Titanium Rod.
