AMS 4965 - Bars, Forgings (Solution treated and aged)
AMS 4967 - Bars, Forgings (Annealed, Heat Treatable)
HEAT TREATMENT
- For high hardness, tensile strength, 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 in heat treatment options. - 1. Anneal: 1,275 -1,400°F (691 - 760°C) for ½ to 2 hours, air or furnace cool
- 2. Stress Relief Anneal: 1,000 -1,200°F (538 - 649°C) for 1 to 8 hours, air or furnace cool
- 3. Solution Heat Treat: 1,675 -1,750°F (913 - 954°C) for 1 hour, water quench
- 4. Aging: 975 -1,025°F (524 - 552°C) for 4 to 8 hours - air cool
In the solution treated and aged condition, rapid quenching of smaller sections yields optimal properties. Larger section sizes or delayed quenching may result in suboptimal properties.
HARDNESS
Typical hardness in the annealed state is Rockwell C 30-34, and around 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 35% reduction is recommended for achieving optimum properties.
- Ti-6Al-4V, Grade 5 alloy bar presents challenges in forming at room temperature, even when annealed. To perform severe forming tasks like bending or stretching, the material should be annealed and heated up to 1,200°F (649°C), ensuring mechanical properties remain intact. For hot sizing or forming, utilize creep forming within the temperature range of 1,000 - 1,200°F (538 - 649°C).
Machinability
Ti-6Al-4V, Grade 5 alloy bar can be effectively machined using methods designed for austenitic stainless steel. This requires slow machining speeds, high feeds, rigid tools, and copious amounts of non-chlorinated cutting fluids to achieve precision.
Weldability
Ti-6Al-4V, Grade 5 alloy rod is highly weldable in both the annealed and solution-aged states, with aging performed during post-weld heat treatment. It is essential to avoid contamination with oxygen, nitrogen, and hydrogen. Fusion welding should be done in an inert gas atmosphere, employing a tail shield to protect the molten metal and adjacent zones. Additionally, spot, seam, and flash welding can be conducted without protective atmospheres.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rod may suffer from hydrogen contamination due to improper pickling, and from oxygen, nitrogen, and carbon during forging, heat treating, or brazing. Such contamination can lead to a loss of ductility, negatively 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 shows the general corrosion rates for Grade 2 titanium in various media. CP titanium demonstrates excellent corrosion resistance across diverse environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion
CP titanium offers superior crevice corrosion resistance in salt solutions compared to stainless steels, with no crevice corrosion at temperatures under 80 °C (176°F) regardless of pH, even under highly chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium boasts excellent resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion
Titanium shows unrivaled erosion resistance in flowing environments.
The material demonstrates impressive resilience in seawater with velocities up to 130 ft/sec (40 m/sec), showing negligible effects. Even the presence of abrasive particles, such as sand, only slightly impacts its corrosion resistance.
Hydrogen Embrittlement
Titanium exhibits remarkable resistance to hydrogen absorption even when exposed to seawater at elevated temperatures. Typically, hydrogen absorption occurs only under the following conditions:
- The pH levels fall below 3 or rise above 12
- Temperatures exceed 176°F (80°C)
- There is a mechanism present for hydrogen generation, such as a galvanic couple or an impressed current.
Bio-Corrosion
Titanium alloys boast exceptional immunity to all forms of microbiologically influenced corrosion. Despite their non-toxicity to marine organisms, biofouling can occur in seawater. This can be effectively managed through chlorination or by increasing water velocity through the heat exchanger.
Corrosion Fatigue
Titanium stands out among materials for maintaining its fatigue performance even in seawater. Fatigue endurance limits and fatigue *** growth rates remain consistent whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is positioned near the noble end close to stainless steels. It typically acts as the cathode when coupled with other metals, thereby remaining unaffected by galvanic corrosion. However, it can accelerate corrosion in the other metal. Coupling with more noble metals like graphite further enhances titanium's passivity.
Fatigue Properties
Grade 2 Titanium Rods do not experience degradation in fatigue properties when exposed to seawater. Both fatigue endurance limits and fatigue *** growth rates are consistent in air or seawater tests.
Weldability
CP2 Grade Titanium Rod offers exceptional weldability, provided that necessary precautions are taken. 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 grease or oil contamination.
Grade 2 Titanium Rods are typically welded using manual or automatic TIG welding, with or without filler wire. To minimize the size of the heat-affected zone, low heat input should be used. Typically, Titanium Rods are not post-weld heat treated.
