HEAT TREATMENT
- To achieve optimal hardness, tensile strength, and fatigue strength, annealing can be conducted at 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy offers a variety of 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 smaller sections yields optimal properties. However, larger sections and/or delayed quenching may lead to suboptimal properties.
HARDNESS
Typical hardness in the annealed state ranges from Rockwell C 30-34, and approximately Rockwell C 35-39 in the solution-treated and aged state.
Forgeability/Formability
- Ti-6Al-4V, Grade 5 alloy bar is forged at 1,750°F; (954°C) with a final forging temperature of 1,450°F; (788°C). For optimal properties, a minimum reduction of 35% is recommended.
- Ti-6Al-4V, Grade 5 alloy bar exhibits difficulty forming at room temperature, even in the annealed condition. Severe forming operations such as bending or stretching should be performed on annealed material at temperatures up to 1,200°F; (649°C) to preserve mechanical properties. Hot sizing or forming can be accomplished through creep forming within the range of 1,000 - 1,200°F; (538 - 649°C).
Machinability
Ti-6Al-4V, Grade 5 alloy bar can be machined using machining methods for austenitic stainless steel, requiring slow machining speeds, high feeds, rigid tools, and abundant use of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is highly weldable in its annealed state or in a solution and partially aged condition. Aging can be achieved during post-weld heat treatment. To ensure quality, it is crucial to avoid contamination with oxygen, nitrogen, and hydrogen. Fusion welding should be performed in an inert gas-filled chamber or with inert gas, covering the molten metal and adjacent heated zones with a tail shield. Additionally, spot, seam, and flash welding can be conducted without needing a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is prone to contamination from hydrogen during improper pickling and from oxygen, nitrogen, and carbon during forging, heat treating, and brazing. Such contamination can lead to a significant loss of ductility, resulting in negative impacts on notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Unmatched Corrosion Resistance
Titanium should not be exposed to strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion Properties
Find the general corrosion rates for Grade 2 titanium across various media in Table 1. Commercially Pure (CP) titanium offers exceptional resistance to a broad range of environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organic Compounds and Organic Acids
- Sulfur Compounds
Outstanding Crevice Corrosion Resistance
CP titanium provides 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 Resistance
Grade 2 titanium excels in resisting stress corrosion (SCC) cracking in hot chloride solutions and is impervious to SCC in seawater.
Robust Erosion Corrosion Resistance
Titanium demonstrates excellent erosion resistance in flowing
seawater at velocities up to 130 ft/sec (40 m/sec), showing minimal effect on the material. The presence of abrasive particles, like sand, has a negligible impact on corrosion.
Hydrogen Embrittlement Prevention
Titanium does not significantly absorb hydrogen when exposed to seawater, even at elevated temperatures. Typically, hydrogen absorption only occurs under the following conditions:
- pH levels are < 3 or > 12
- Temperature exceeds 176°F (80°C)
- Presence of a hydrogen-generating mechanism, such as a galvanic couple or impressed current.
Exceptional Bio-Corrosion Resistance
Titanium alloys possess an extraordinary immunity to all forms of microbiologically influenced corrosion. These alloys exhibit no toxicity to marine organisms, allowing biofouling in seawater environments. However, this can be controlled effectively through chlorination or by enhancing the water velocity within the heat exchanger.
Corrosion Fatigue
Unlike many other materials, titanium does not experience a reduction in fatigue performance when exposed to seawater. Both the fatigue endurance limits and the rates of fatigue *** growth remain consistent whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is situated towards the noble end near stainless steels, typically acting 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. When coupled with more noble metals like graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod stands out because it does not suffer from fatigue property degradation in seawater. The fatigue endurance limits and fatigue *** growth rates are identical, regardless of whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod is exceptionally weldable when proper precautions are adhered to. Given titanium's high reactivity, an inert gas shield must be applied to both the OD and ID of the rod. Additionally, the material must be free from grease or oil contamination.
Grade 2 Titanium Rod is typically welded using manual or automatic TIG welding, either with or without filler wire. To minimize the heat-affected zone, low heat input should be utilized. Post-weld heat treatment is generally not applied to Titanium Rod.
