AMS 4965 - Bars, Forgings (Solution treated and aged)
AMS 4967 - Bars, Forgings (Annealed, Heat Treatable)
HEAT TREATMENT
- For high hardness, tensile, and fatigue strength, annealing can be executed at 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4™ Grade 5 alloy is versatile for various heat treatments. - 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
Rapid quenching in the solution-treated state maximizes properties for small sections. Larger sections or delayed quenching can result in suboptimal properties.
HARDNESS
Typical hardness is Rockwell C 30-34 in the annealed state and Rockwell C 35-39 in the solution 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). A minimum of 35% reduction ensures optimal properties.
- Ti-6Al-4V, also recognized as Grade 5 alloy bar, presents a significant challenge when forming at room temperature, even in its annealed condition. However, for more intensive forming operations such as bending or stretching, annealed material can be efficiently processed at temperatures soaring up to 1,200°F (649°C) without compromising its mechanical integrity. The art of hot sizing or forming is perfected through creep forming within a temperature spectrum of 1,000 - 1,200°F (538 - 649°C).
Machinability
Ti-6Al-4V, Grade 5 alloy bar can be expertly machined using methods akin to those for austenitic stainless steel. This involves the implementation of slow machining speeds, robust feeds, and the employment of rigid tools. An ample application of non-chlorinated cutting fluids ensures effective machining.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod boasts excellent weldability in both the annealed condition or when solution and partially aged, with aging achieved during post-weld heat treatment. Attention to detail is necessary to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding is recommended within an inert gas-filled chamber or utilizing an inert gas to protect the molten metal and adjacent zones with a tail shield. Additionally, spot, seam, and flash welding can be performed without the need for a protective atmosphere.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rod may face contamination from hydrogen during improper pickling, and from oxygen, nitrogen, and carbon during processes such as forging, heat treating, and brazing. Such contamination can lead to a loss of ductility, adversely impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Corrosion resistance
Titanium should be avoided with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General corrosion
General corrosion rates for Grade 2 titanium in varied media are shown in Table 1. CP titanium boasts excellent corrosion resistance to numerous environments, including:
- Seawater and brines
- Inorganic salts
- Moist *** gas
- Alkaline solutions
- Oxidizing acids
- Organics and organic acids
- Sulfur compounds
Crevice corrosion
CP titanium shows strong resistance to crevice corrosion in salt solutions compared to stainless steels. CP titanium resists crevice corrosion at temperatures below 80 °C (176°F), regardless of pH, even under super chlorinated conditions.
Stress corrosion cracking
Grade 2 titanium demonstrates exceptional resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion corrosion
Titanium exhibits remarkable resistance to erosion in flowing environments.
Experience the unparalleled resilience of our titanium rods, capable of withstanding seawater velocities up to 130 ft/sec (40 m/sec) without significant material degradation. Even the presence of abrasive particles like sand causes only minimal corrosion.
Understanding Hydrogen Embrittlement in Titanium
Titanium exhibits exceptional resistance to hydrogen absorption, even when exposed to seawater at elevated temperatures. Hydrogen uptake is typically only a concern under specific conditions:
- The pH level is below 3 or above 12.
- The temperature exceeds 176°F (80°C).
- There is an active mechanism for hydrogen generation, such as a galvanic couple or an impressed current.
Bio-corrosion Resistance
Titanium alloys show unique immunity to all forms of microbiologically influenced corrosion. Although they do not exhibit toxicity towards marine organisms, which can lead to biofouling in seawater, this can be managed through chlorination or by increasing water velocity through heat exchangers.
Corrosion Fatigue Resistance
Unlike many materials, titanium maintains its fatigue performance in seawater. Fatigue endurance limits and *** growth rates remain consistent whether tested in air or seawater, ensuring long-lasting durability.
Galvanic Corrosion Characteristics
Titanium stands near the noble end of the galvanic series, close to stainless steels, typically acting as the cathode when paired with other metals. This makes titanium resistant to galvanic corrosion, although it may accelerate the corrosion of the other metal. Pairing titanium with more noble metals, such as graphite, further enhances its passivity.
Superior Fatigue Properties
Grade 2 Titanium Rods exhibit extraordinary fatigue resistance, maintaining performance in the presence of seawater. Fatigue *** growth rates and endurance limits are unaffected, whether in air or seawater.
Weldability of Titanium Rods
CP2 Grade Titanium Rod is highly weldable with proper precautions. Due to titanium's reactivity, an inert gas shield must be applied on both the outside and inside surfaces. Ensure the material is free from grease or oil contaminants before welding.
Typically, Grade 2 Titanium Rods are welded using manual or automatic TIG welding, with or without filler wire. To minimize the heat-affected zone, a low heat input should be used. Post-weld heat treatment is not usually required.
