HEAT TREATMENT
- For applications requiring high hardness, tensile strength, and fatigue strength, annealing can be performed at temperatures ranging from 1,700-1,900°F (927 - 1,038°C).
Our proprietary DAXUN 6-4™ Grade 5 alloy can undergo a variety of heat treatment processes. - 1. Anneal: 1,275 -1,400°F (691 - 760°C), maintained for ½ to 2 hours, and then cooled in air or furnace.
- 2. Stress Relief Anneal: 1,000 -1,200°F (538 - 649°C), maintained for 1 to 8 hours, then air or furnace-cooled.
- 3. Solution Heat Treat: 1,675 -1,750°F (913 - 954°C), maintained for 1 hour, followed by a water quench.
- 4. Aging: 975 -1,025°F (524 - 552°C), maintained for 4 to 8 hours, followed by air cooling.
In the solution treated and aged condition, rapid quenching of smaller sections delivers optimal properties. However, larger sections and/or delayed quenching might yield properties that are less than optimal.
HARDNESS
The typical hardness in the annealed condition ranges from Rockwell C 30-34, while in the solution treated and aged condition, it ranges from Rockwell C 35-39.
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 of 35% reduction is recommended to achieve optimum properties.
- Forming Ti-6Al-4V, Grade 5 alloy bars at room temperature is challenging, even in the annealed condition. Therefore, severe forming operations such as bending or stretching should be performed on annealed material at temperatures up to 1,200°F (649°C) to avoid compromising mechanical properties. Hot sizing or forming can be achieved via creep forming within the temperature range of 1,000 - 1,200°F (538 - 649°C).
Machinability
Ti-6Al-4V, Grade 5 alloy bars can be machined using techniques suitable for austenitic stainless steel, with slow machining speeds, high feeds, robust tools, and abundant use of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is readily weldable whether in the annealed condition or in the solution and partially aged condition, with the aging process completed during post-weld heat treatment. It's crucial to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding should be done in an inert gas-filled chamber or with inert gas to shield the molten metal and heated zones, using a tail shield. Spot, seam, and flash welding can be performed without needing a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod can be contaminated with hydrogen from improper pickling, as well as with oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such contamination leads to a loss of ductility, adversely impacting 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 general corrosion rates for Grade 2 titanium across various media. CP titanium demonstrates exceptional corrosion resistance in a multitude of environments, including:
- Seawater and brines
- Inorganic salts
- Moist *** gas
- Alkaline solutions
- Oxidizing acids
- Organics and organic acids
- Sulfur compounds
Crevice Corrosion
CP titanium shows formidable resistance to crevice corrosion in salt solutions, outperforming stainless steels. It resists crevice corrosion at temperatures below 80 °C (176°F), regardless of pH, even under super chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium is highly resistant to stress corrosion cracking in hot chloride solutions and remains immune in seawater.
Erosion Corrosion
Titanium offers outstanding erosion resistance in flowing
seawater at velocities up to 130 ft/sec (40 m/sec), with minimal effect on the material. The presence of abrasive particles like sand only slightly impacts corrosion.
Hydrogen Embrittlement
Titanium shows no significant hydrogen absorption in seawater, even at elevated temperatures. Hydrogen absorption typically occurs only under these conditions:
- pH < 3 or > 12
- Temperature > 176F (80C)
- Presence of a hydrogen generation mechanism such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys exhibit remarkable immunity to all forms of microbiologically influenced corrosion, ensuring long-lasting durability. Although biofouling can occur in seawater due to titanium's non-toxicity to marine organisms, this can be effectively mitigated by chlorination or increased water velocity through heat exchangers.
Resistance to Corrosion Fatigue
Titanium stands out from other materials as it maintains fatigue performance even in seawater. Fatigue endurance limits and *** growth rates remain consistent whether tested in air or seawater, ensuring reliable performance in marine environments.
Exceptional Galvanic Corrosion Resistance
Titanium, positioned towards the noble end of the galvanic series near stainless steels, typically acts as the cathode when paired with other metals. This means it resists galvanic corrosion but can accelerate the corrosion of the coupled metal. When paired with more noble metals, like graphite, titanium's passivity is further enhanced.
Superior Fatigue Properties
Grade 2 Titanium Rods exhibit excellent fatigue properties, unaffected by seawater. The endurance limits and *** growth rates are consistent whether in air or seawater, making them ideal for marine applications.
Outstanding Weldability
CP2 Grade Titanium Rods are highly weldable with proper precautions. An inert gas shield must cover both the rod's OD and ID due to titanium's reactivity. Additionally, the rods must be free from grease or oil contamination for optimal weld quality.
Grade 2 Titanium Rods are usually welded using manual or automatic TIG welding, with or without filler wire. To minimize the heat-affected zone, low heat input is recommended. Typically, post-weld heat treatment is not required for Titanium Rods.
