SPECIFICATIONS
AMS 4928 - Bars, Forgings, and Forging Stock (Annealed)
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 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), 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.
In the solution-treated and aged condition, rapid quenching of smaller sections yields optimal properties, while larger sections and/or delayed quenching may result in sub-optimal properties.
HARDNESS
Typical hardness is Rockwell C 30-34 in the annealed condition and Rockwell C 35-39 in the solution and aged condition.
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 is recommended to achieve optimal properties.
- The Ti-6Al-4V, Grade 5 alloy bar, known for its formidable strength, presents challenges in room-temperature forming, even when annealed. To achieve severe forming operations like bending or stretching without compromising mechanical properties, the material should be annealed and processed at temperatures up to 1,200°F (649°C). Hot sizing or forming is best performed through creep forming within a 1,000 - 1,200°F (538 - 649°C) range.
Machinability
Harnessing the exceptional properties of the Ti-6Al-4V, Grade 5 alloy bar requires precision. This titanium alloy can be efficiently machined using austenitic stainless steel methods, employing slow machining speeds, high feeds, robust tools, and ample non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod excels in weldability, whether in the annealed state or partially aged condition. Post-weld heat treatment allows aging. Vigilant measures are needed to guard against contamination from oxygen, nitrogen, and hydrogen. Fusion welding demands an inert gas-filled chamber or inert gas shielding to protect the molten metal and adjacent heated areas. Spot, seam, and flash welding techniques can be executed without a protective atmosphere.
Special Considerations
Ensuring the purity of Ti-6Al-4V, Grade 5 titanium alloy rod is paramount. It can be tainted by hydrogen during improper pickling and by oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such contaminations reduce ductility, leading to heightened notch sensitivity and compromised forming characteristics.

Grade 2 Titanium Rod: Superior Quality
Outstanding Corrosion Resistance
Avoid using titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous *** to maintain its integrity.
General Corrosion: Unmatched Durability
Table 1 showcases the corrosion rates for Grade 2 titanium across various media. CP titanium stands out for its excellent corrosion resistance in various environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organic Compounds and Organic Acids
- Sulfur Compounds
Exceptional Crevice Corrosion Resistance
CP titanium provides superior resistance to crevice corrosion in salt solutions compared to stainless steels. CP titanium remains free from crevice corrosion at temperatures below 80 °C (176°F) regardless of pH, even in highly chlorinated conditions.
Stress Corrosion Cracking: Notable Resilience
Grade 2 titanium offers unparalleled resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion: Exceptional Resistance
Titanium delivers excellent resistance to erosion in flowing environments.
When subjected to seawater velocities up to 130 ft/sec (40 m/sec), our titanium shows negligible degradation. Even in the presence of abrasive particles like sand, the material's corrosion resistance remains largely unaffected.
Hydrogen Embrittlement
Titanium remains largely impervious to hydrogen absorption, even in seawater at elevated temperatures. Hydrogen absorption typically occurs only if the following conditions are met:
- 1. The pH is < 3 or > 12
- 2. The temperature exceeds 176°F (80°C)
- 3. There is a hydrogen-generating mechanism, such as a galvanic couple or an impressed current.
Bio-Corrosion
Titanium alloys exhibit a remarkable resistance to microbiologically influenced corrosion (MIC). However, as they are non-toxic to marine organisms, biofouling can still occur in seawater environments. This can be controlled through chlorination or by increasing the water velocity in heat exchangers.
Corrosion Fatigue
Unlike many materials, titanium's fatigue performance is not compromised by exposure to seawater. Fatigue endurance limits and *** growth rates remain consistent in both air and seawater environments.
Galvanic Corrosion
In the galvanic series, titanium is positioned towards the noble end, near stainless steels. It typically acts as the cathode when coupled with other metals, hence it is resistant to galvanic corrosion but can accelerate corrosion in the coupled metal. Coupling titanium with more noble metals, like graphite, further enhances its passivity.
Fatigue Properties
Grade 2 Titanium Rod distinguishes itself by maintaining its fatigue properties even in the presence of seawater. Fatigue endurance limits and *** growth rates remain the same whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod is highly weldable, provided appropriate precautions are taken. Due to titanium's reactivity, an inert gas shield must be used on both the OD and ID of the rod. Additionally, the material needs to be free from any grease or oil contamination.
Grade 2 Titanium Rod can be welded using manual or automatic TIG welding, with or without filler wire. Low heat input is recommended to minimize the heat-affected zone, and typically, the Titanium Rod is not post-weld heat treated.
