HEAT TREATMENT
- For applications requiring high hardness, tensile strength, and fatigue resistance, annealing can be conducted at temperatures ranging from 1,700°F to 1,900°F (927°C - 1,038°C).
DAXUN 6-4™ Grade 5 alloy offers versatile heat treatment options for optimizing performance. - 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 ensures optimum properties. Larger sections or delayed quenching may yield suboptimal properties.
HARDNESS
Typically, the hardness in the annealed condition ranges from Rockwell C 30-34, and in the solution and aged state, it ranges from Rockwell C 35-39.
Forgeability/Formability
- Ti-6Al-4V, Grade 5 alloy bar can be forged at 1,750°F (954°C) with a final forging temperature of 1,450°F (788°C). For optimal properties, a minimum of 35% reduction is recommended.
- Ti-6Al-4V, Grade 5 alloy bar presents challenges for forming at room temperature, even in the annealed state. Consequently, severe forming operations, such as bending or stretching, should be performed on annealed material at temperatures up to 1,200°F (649°C) to maintain mechanical properties. Hot sizing or forming can be achieved through creep forming within 1,000 - 1,200°F (538 - 649°C).
Machinability
Ti-6Al-4V, Grade 5 alloy bar is machinable using austenitic stainless steel methods, which involve slow speeds, high feed rates, rigid tools, and abundant use of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is exceptionally versatile, easily weldable whether in its annealed state or after undergoing solution and partial aging treatments. For optimal results and to prevent contamination, it's crucial to shield the material from oxygen, nitrogen, and hydrogen exposure. Fusion welding should occur in an inert gas-filled chamber, or alternatively, using an inert gas to safeguard both the molten metal and the adjacent heated zones, supplemented by a tail shield. Spot, seam, and flash welding are achievable without the need for a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod requires meticulous handling due to potential hydrogen contamination from improper pickling and exposure to oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such contamination can lead to decreased ductility, negatively impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Superior Corrosion Resistance
Titanium should not be used with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion
The general corrosion rates for Grade 2 titanium in various media are detailed in Table 1. CP titanium offers exceptional corrosion resistance across a wide range of environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion
CP titanium demonstrates superior resistance to crevice corrosion in salt solutions compared to stainless steels. It will not exhibit crevice corrosion at temperatures below 80 °C (176°F), irrespective 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 is immune to SCC in seawater.
Erosion Corrosion
Titanium offers excellent resistance to erosion in flowing
seawater at velocities up to 130 ft/sec (40 m/sec), with minimal effect on the material. The presence of abrasive particles, such as sand, only minorly impacts corrosion.
Hydrogen Embrittlement
Titanium doesn't significantly absorb hydrogen when exposed to seawater, even at elevated temperatures. Hydrogen absorption generally occurs only under the following conditions:
- pH is < 3 or > 12
- Temperature exceeds 176°F (80°C)
- A mechanism such as a galvanic couple or impressed current facilitates hydrogen generation.
Bio-Corrosion
Titanium alloys boast an exceptional resistance to microbiologically influenced corrosion. Unlike other metals, titanium alloys exhibit no toxicity to marine organisms, which means biofouling can occur in seawater environments. However, this can be effectively managed through chlorination or by increasing water velocity through the heat exchanger.
Corrosion Fatigue
Titanium stands out by maintaining its fatigue performance even in seawater conditions. Whether tested in air or seawater, its fatigue endurance limits and fatigue *** growth rates remain consistent.
Galvanic Corrosion
In the galvanic series, titanium is positioned toward the noble end, near stainless steels, and typically acts as the cathode when paired with other metals. Therefore, it resists galvanic corrosion but can accelerate the corrosion of the other metal. Pairing titanium with more noble metals like graphite further enhances its passivity.
Fatigue Properties
Grade 2 Titanium Rod uniquely retains its fatigue properties even in seawater. Its fatigue endurance limits and fatigue *** growth rates are identical whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable given proper precautions. Due to titanium's reactivity, an inert gas shield must be used on both the OD and ID of the rod, and the material must be free from any grease or oil contaminants.
Grade 2 Titanium Rod typically undergoes manual or automatic TIG welding, with or without filler wire. Low heat input is crucial to minimize the heat-affected zone. Post-weld heat treatment is generally not required.
