AMS 4965 - Bars, Forgings (Solution Treated and Aged)
AMS 4967 - Bars, Forgings (Annealed, Heat Treatable)
HEAT TREATMENT
- For applications requiring high hardness, tensile strength, and fatigue strength, annealing can be executed at temperatures between 1,700-1,900°F (927-1,038°C).
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 smaller sections yields optimal properties, while larger sections or delayed quenching may result in sub-optimal properties.
HARDNESS
The typical hardness in the annealed condition ranges from Rockwell C 30-34, and in the solution and aged condition, it is around Rockwell C 35-39.
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 reduction of at least 35% is recommended for achieving the best properties.
- The Ti-6Al-4V, Grade 5 alloy bar is notably challenging to form at room temperature, even when annealed. To accommodate severe forming operations like bending or stretching, the material should be heated up to 1,200°F (649°C), ensuring mechanical properties remain unaffected. Furthermore, hot sizing or forming is achievable through creep forming within the 1,000 - 1,200°F (538 - 649°C) temperature range.
Machinability
The Ti-6Al-4V, Grade 5 alloy bar can be machined efficiently using austenitic stainless steel machining techniques. This requires slow machining speeds, high feed rates, rigid tools, and generous use of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod offers excellent weldability whether in the annealed state or the solution and partially aged condition, with aging typically performed during post-weld heat treatment. It is crucial to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding should be conducted in an inert gas-filled chamber or using inert gas to shield the molten metal and adjacent heated zones, complemented by a tail shield. Spot, seam, and flash welding can be done without a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to contamination by hydrogen from improper pickling, as well as by oxygen, nitrogen, and carbon during forging, heat treating, or brazing. Such contamination can lead to a reduction in ductility, adversely impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod - Excellence in Material
Outstanding Corrosion Resistance
Avoid using titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion Resistance
The general corrosion rates for Grade 2 titanium in various media are detailed in Table 1. Commercially Pure (CP) titanium offers impressive resistance to a broad range of environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Exceptional Crevice Corrosion Resistance
CP titanium stands out for its resistance to crevice corrosion in salt solutions, outperforming stainless steels. It remains crevice corrosion-free under 80°C (176°F), across all pH levels, even in highly chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium ensures superior resistance to stress corrosion cracking in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion Resistance
Titanium excels in resisting erosion in flowing environments
Experience the unparalleled durability of our materials in harsh marine environments! Even when exposed to seawater velocities of up to 130 ft/sec (40 m/sec), our titanium rods show negligible degradation. The presence of abrasive particles, such as sand, has only a minimal effect on corrosion, ensuring longevity and reliability.
Hydrogen Embrittlement
Rest easy knowing that our titanium rods exhibit no significant hydrogen absorption, even when exposed to seawater and high temperatures. Hydrogen absorption typically requires three specific conditions to be met:
- 1. pH levels are below 3 or above 12.
- 2. Temperatures exceed 176°F (80°C).
- 3. A mechanism exists for hydrogen generation, such as a galvanic couple or an impressed current.
Bio-Corrosion
Our advanced titanium alloys showcase an exceptional immunity to all forms of microbiologically influenced corrosion. While these alloys are non-toxic to marine organisms and thus susceptible to biofouling, this can be effectively managed through chlorination or by increasing water velocity in heat exchangers.
Corrosion Fatigue
Unlike many other materials, our titanium rods maintain their fatigue performance even in seawater. Both their fatigue endurance limits and fatigue *** growth rates remain consistent, whether tested in air or seawater.
Galvanic Corrosion
Positioned towards the noble end of the galvanic series near stainless steels, titanium typically acts as a cathode when paired with other metals. Consequently, titanium remains unaffected by galvanic corrosion but may accelerate the corrosion of the coupled metal. Pairing titanium with more noble metals, like graphite, enhances titanium's passivity further.
Fatigue Properties
Our Grade 2 Titanium Rods are second to none in maintaining fatigue properties in the presence of seawater. Their fatigue endurance limits and fatigue *** growth rates remain consistent whether in air or seawater.
Weldability
Our CP2 Grade Titanium Rods are highly weldable with the right precautions. Given titanium's reactivity, an inert gas shield is essential on both the outer and inner diameters. Ensure the material is free from grease or oil to guarantee optimal results.
Grade 2 Titanium Rods are best welded using manual or automatic TIG welding, with or without filler wire. Utilize low heat input to minimize the heat affected zone size. Post-weld heat treatment is typically unnecessary for Titanium Rods.
