HEAT TREATMENT
- When high hardness, tensile strength, and fatigue strength are required, annealing can be performed at 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 small sections yields optimum properties. Larger section sizes and/or delayed quenching may result in sub-optimal properties.
HARDNESS
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
- The 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). For optimum properties, a minimum of 35% reduction is recommended.
- Though challenging to form at room temperature, the Ti-6Al-4V, Grade 5 alloy bar can undergo severe forming operations such as bending or stretching on annealed material at temperatures up to 1,200°F (649°C) without compromising mechanical properties. Hot sizing or forming can be achieved through creep forming in the range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar can be efficiently machined using austenitic stainless steel machining techniques, incorporating slow speeds, high feeds, rigid tools, and generous amounts of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod offers excellent weldability, whether in its annealed state or after solution and partial aging treatments - with aging facilitated through post-weld heat treatment. To ensure the highest quality, precautions are essential to avoid contamination from oxygen, nitrogen, and hydrogen. Fusion welding is best performed within an inert gas environment to shield the molten metal and the heated adjacent zones, often using a tail shield. Moreover, spot, seam, and flash welding can be executed without the necessity of a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod must be carefully handled to prevent contamination. Improper pickling can introduce hydrogen, while forging, heat treating, and brazing may expose it to oxygen, nitrogen, and carbon. Such contamination can significantly reduce ductility, negatively impacting notch sensitivity and forming properties.

Grade 2 Titanium Rod
Exceptional Corrosion Resistance
Note: Titanium should be avoided in environments with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion Properties
Table 1 illustrates the general corrosion rates for Grade 2 titanium across various media. Commercially Pure (CP) titanium demonstrates excellent resistance to a wide range of environments, including:
- Resistance to Seawater and Brines
- Inorganic Salts Compatibility
- Moist *** Gas Resilience
- Durability in Alkaline Solutions
- Sturdiness against Oxidizing Acids
- Resistance to Organics and Organic Acids
- Sulfur Compound Endurance
Crevice Corrosion Resistance
CP titanium offers superior resistance to crevice corrosion in salt solutions compared to stainless steels. It remains unaffected by crevice corrosion at temperatures below 80°C (176°F), regardless of pH, even in highly chlorinated conditions.
Stress Corrosion Cracking (SCC) Resistance
Grade 2 titanium boasts remarkable resistance to SCC in hot chloride solutions and remains immune in seawater environments.
Erosion Corrosion Resilience
Titanium is highly resistant to erosion in flowing
seawater, maintaining integrity at velocities up to 130 ft/sec (40 m/sec). The presence of abrasive particles, such as sand, only minimally affects its corrosion resistance.
Hydrogen Embrittlement Prevention
Titanium exhibits minimal hydrogen absorption in seawater, even at elevated temperatures. Notably, hydrogen absorption typically occurs only under the following conditions:
- pH levels are < 3 or > 12
- Temperatures exceed 176°F (80°C)
- Presence of a hydrogen generation mechanism, such as a galvanic couple or impressed current.
Bio-Corrosion Resistance
Titanium alloys exhibit an unparalleled immunity to all forms of microbiologically influenced corrosion. Remarkably, these alloys are non-toxic to marine organisms, which can lead to biofouling in seawater. This issue can be effectively controlled through chlorination or by increasing the water flow velocity in heat exchangers.
Corrosion Fatigue
Unlike many other materials, titanium maintains its fatigue performance even in the presence of seawater. The fatigue endurance limits and *** growth rates of titanium are consistent whether tested in air or seawater, making it an exceptional choice for marine applications.
Galvanic Corrosion
In the galvanic series, titanium is positioned near stainless steels, acting as a noble metal. Typically, it serves as the cathode when paired with other metals, thus remaining unaffected by galvanic corrosion. However, it can accelerate the corrosion of the less noble metal. Pairing titanium with more noble materials like graphite enhances its passivity significantly.
Fatigue Properties
Grade 2 Titanium Rod distinguishes itself by maintaining its fatigue properties in seawater, unlike many other materials. Its fatigue endurance limits and *** growth rates remain stable whether tested in air or seawater, ensuring reliable performance in marine environments.
Weldability
CP2 Grade Titanium Rod boasts excellent weldability, provided the necessary precautions are taken. Due to titanium's reactivity, an inert gas shield must be applied to both the OD and ID of the rod. It's crucial to ensure the material is free from any grease or oil contamination.
Grade 2 Titanium Rod is typically welded using manual or automatic TIG welding, with or without filler wire. Employing low heat input minimizes the heat-affected zone's size. Notably, post-weld heat treatment for Titanium Rod is generally unnecessary.
