AMS 4967: Bars, Forgings (Annealed, Heat Treatable).
HEAT TREATMENT: Precision and Performance.
- Optimal Heat Treatment: For high hardness, tensile strength, and fatigue strength, perform annealing at 1,700-1,900°F (927 - 1,038°C).
Versatile Heat Treatment for DAXUN 6-4™ Grade 5 Alloy. - 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.
Achieve Optimal Properties with Rapid Quenching: In the solution treated and aged condition, rapid quenching of small sections ensures peak properties, while larger sections and/or delayed quenching yield less optimal results.
HARDNESS: Superior Strength.
Typical Hardness: Achieve Rockwell C 30-34 in the annealed condition and Rockwell C 35-39 in the solution and aged condition.
Forgeability/Formability: Ensuring ease of manufacturing and quality.
- The Ti-6Al-4V, Grade 5 alloy bar undergoes forging at a robust 1,750°F (954°C), with the final forging temperature set at 1,450°F (788°C). To achieve optimal properties, a minimum of a 35% reduction is highly recommended.
- Due to its nature, the Ti-6Al-4V, Grade 5 alloy bar presents challenges in forming at room temperature, even when annealed. Thus, severe forming operations such as bending or stretching are ideally performed on annealed material at temperatures reaching up to 1,200°F (649°C) without compromising its mechanical integrity. Furthermore, hot sizing or forming can be efficiently executed through creep forming within the temperature range of 1,000 - 1,200°F (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar can be precisely machined utilizing methods akin to those for austenitic stainless steel, employing slow machining speeds, high feeds, sturdy tools, and copious amounts of non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is highly weldable in both the annealed condition and the solution and partially aged condition, with aging achieved during post-weld heat treatment. It is crucial to avoid contamination by oxygen, nitrogen, and hydrogen. Fusion welding can be performed in an inert gas-filled chamber or using inert gas to weld the molten metal and surrounding heated zones, including a tail shield. Spot, seam, and flash welding can also be achieved without the need for a protective atmosphere.
Special Considerations
Attention must be paid to the potential contamination of the Ti-6Al-4V, Grade 5 titanium alloy rod, which may absorb hydrogen during improper pickling and 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 characteristics.

Grade 2 Titanium Rod
Corrosion Resistance
Avoid using titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion
The general corrosion rates for Grade 2 titanium in various media are documented in Table 1. CP Titanium demonstrates remarkable corrosion resistance across a broad spectrum of environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Crevice Corrosion
CP Titanium offers outstanding resistance to crevice corrosion in salt solutions, surpassing stainless steels. It does not exhibit crevice corrosion at temperatures below 80°C (176°F) regardless of pH, even in highly chlorinated conditions.
Stress Corrosion Cracking
Grade 2 titanium exhibits outstanding resistance to stress corrosion cracking (SCC) in hot chloride solutions and remains completely immune to SCC in seawater, making it an ideal choice for marine applications.
Erosion Corrosion
Titanium demonstrates exceptional resistance to erosion in flowing environments, ensuring longevity and durability.
In seawater with velocities up to 130 ft/sec (40 m/sec), titanium shows negligible corrosion, even when abrasive particles like sand are present.
Hydrogen Embrittlement
Titanium absorbs minimal hydrogen when exposed to seawater, even at elevated temperatures. Hydrogen absorption only occurs under specific conditions:
- 1. pH is < 3 or > 12
- 2. Temperature exceeds 176°F (80°C)
- 3. A mechanism for hydrogen generation exists, such as a galvanic couple or impressed current.
Bio-Corrosion
Titanium alloys exhibit unique immunity to microbiologically influenced corrosion (MIC). Biofouling in seawater can be minimized by chlorination or increasing water velocity through the heat exchanger.
Corrosion Fatigue
Titanium maintains its fatigue performance in seawater, with no reduction in fatigue endurance limits or fatigue *** growth rates compared to air.
Galvanic Corrosion
In the galvanic series, titanium is near stainless steels and typically acts as the cathode when coupled with other metals, thus protecting itself from galvanic corrosion but potentially accelerating corrosion in the other metal. Coupling with more noble metals enhances titanium's passivity.
Fatigue Properties
Grade 2 Titanium Rod maintains its fatigue properties in seawater, with fatigue endurance limits and *** growth rates consistent in both air and seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable with proper precautions. An inert gas shield must be used on both OD and ID, and the material must be free from grease or oil contamination.
Grade 2 Titanium Rod is typically welded using manual or automatic TIG welding, with or without filler wire. Low heat input is essential to minimize the heat-affected zone size. Post-weld heat treatment is not usually required.
