AMS 4967 - Bars, Forgings (Annealed, Heat Treatable)
HEAT TREATMENT
- For enhanced hardness, tensile strength, and fatigue resistance, annealing can be performed at 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, 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 small sections yields optimal properties. Larger sections or delayed quenching might result in suboptimal properties.
HARDNESS
In the annealed state, typical hardness ranges from Rockwell C 30-34. In the solution-treated and aged state, it reaches Rockwell C 35-39.
Forgeability/Formability
- The Ti-6Al-4V, Grade 5 alloy bar undergoes forging at an intense 1,750°F (954°C) with a final forging mark of 1,450°F (788°C). For achieving peak properties, a minimum reduction of 35% is recommended.
- Crafting Ti-6Al-4V, Grade 5 alloy bar at room temperature proves challenging, even when annealed. Hence, severe forming actions-like bending or stretching-can be executed on annealed material at temperatures up to 1,200°F (649°C) without compromising mechanical properties. Hot sizing or forming can be effectively achieved by creep forming within the 1,000 - 1,200°F (538 - 649°C) range.
Machinability
The Ti-6Al-4V, Grade 5 alloy bar is machinable using methods designed for austenitic stainless steel. This includes slow machining speeds, high feeds, robust tools, and copious amounts of non-chlorinated cutting fluids.
Weldability
In its annealed or solution and partially aged condition, the Ti-6Al-4V, Grade 5 alloy rod exhibits commendable weldability. Aging occurs post-weld heat treatment. To prevent contamination from oxygen, nitrogen, and hydrogen, fusion welding should be executed in an inert gas-filled environment or with inert gas shielding the molten metal and adjacent heated zones. Additional methods like spot, seam, and flash welding can be performed sans a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to contamination from hydrogen due to improper pickling, and from oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such contamination can lead to a reduction in ductility, negatively impacting notch sensitivity and forming properties.

Grade 2 Titanium Rod
Superior Corrosion Resistance
Avoid using titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion Performance
The general corrosion rates for Grade 2 titanium in various media are detailed in Table 1. CP titanium boasts excellent corrosion resistance in numerous environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion Resistance
CP titanium demonstrates superior resistance to crevice corrosion in salt solutions compared to stainless steels. It will not experience crevice corrosion at temperatures below 80°C (176°F), regardless of pH, even in highly chlorinated conditions.
Stress Corrosion Cracking Resistance
Grade 2 titanium exhibits unparalleled resistance to stress corrosion cracking (SCC) in hot chloride solutions and remains completely unaffected by SCC in seawater.
Erosion Corrosion
Titanium demonstrates superior resistance to erosion in flowing
seawater at velocities reaching up to 130 ft/sec (40 m/sec), showing negligible impact on the material. Even the presence of abrasive particles like sand has minimal effect on corrosion.
Hydrogen Embrittlement
Titanium does not significantly absorb hydrogen even when exposed to seawater at elevated temperatures. Hydrogen absorption generally occurs only if the following three conditions are satisfied:
- pH levels are < 3 or > 12
- Temperature exceeds 176°F (80°C)
- There is a mechanism for hydrogen generation such as a galvanic couple or an impressed current.
Bio-Corrosion
Titanium alloys showcase a unique immunity to all types of microbiologically influenced corrosion. Biofouling can occur in seawater due to the non-toxicity of titanium alloys towards marine life. This issue can be mitigated through chlorination or increasing water velocity through heat exchangers.
Corrosion Fatigue
Unlike many other materials, titanium's fatigue performance is not compromised in seawater. The fatigue endurance limits and *** 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, typically acting as the cathode when paired with other metals. Consequently, titanium remains unaffected by galvanic corrosion but may accelerate the corrosion of the other metal. Pairing titanium with more noble metals, such as graphite, further enhances titanium's passivity.
Fatigue Properties
Grade 2 Titanium Rod stands out by not showing any degradation in fatigue properties when exposed to seawater. Both fatigue endurance limits and *** growth rates are consistent whether in air or seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable provided the necessary precautions are observed. Due to titanium's reactivity, an inert gas shield must be applied on both the outer and inner diameters of the rod. The rod should also be free of any grease or oil contamination.
Typically, Grade 2 Titanium Rod is welded using manual or automatic TIG welding, with or without filler wire. Using low heat input is crucial to minimize the size of the heat-affected zone. Post-weld heat treatment is generally not performed on titanium rods.
