HEAT TREATMENT
- For applications requiring high hardness, tensile strength, and fatigue strength, 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 to cater to various requirements. - 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 small sections yields optimal properties, whereas larger sections and/or delayed quenching may result in suboptimal properties.
HARDNESS
Typical hardness in the annealed condition ranges from Rockwell C 30-34, while in the solution and aged condition, it ranges from 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 minimum reduction of 35% is recommended to achieve optimal properties.
- Ti-6Al-4V, Grade 5 alloy bar is challenging to form at room temperature, even in its annealed state. Severe forming operations such as bending or stretching can be conducted on annealed material at temperatures up to 1,200°F (649°C) without compromising mechanical properties. Hot sizing or forming can be achieved through creep forming within the range of 1,000-1,200°F (538-649°C).
Machinability
Ti-6Al-4V, Grade 5 alloy bar can be machined using techniques suitable for austenitic stainless steel, including slow machining speeds, high feeds, rigid tools, and the use of abundant non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is eminently weldable, either in its annealed state or in a solution and partially aged state, where aging is completed during post-weld heat treatment. It is crucial to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding should be performed in an inert gas-filled chamber or with an inert gas shield over the molten metal and its adjacent heated zones. Spot, seam, and flash welding can be executed without a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to contamination by hydrogen during improper pickling, and by oxygen, nitrogen, and carbon during forging, heat treating, or brazing. Such contamination can lead to a reduction in ductility, negatively impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod
Exceptional Corrosion Resistance
Titanium is not recommended for use 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. CP titanium offers outstanding corrosion resistance in diverse environments including:
- Seawater and brines
- Inorganic salts
- Moist *** gas
- Alkaline solutions
- Oxidizing acids
- Organic compounds and organic acids
- Sulfur compounds
Crevice Corrosion Resistance
CP titanium demonstrates excellent resistance to crevice corrosion in salt solutions compared to stainless steels. It resists crevice corrosion at temperatures below 80 °C (176°F), regardless of pH, even under super-chlorinated conditions.
Stress Corrosion Cracking Resistance
Grade 2 titanium shows outstanding resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Erosion Corrosion Resistance
Titanium exhibits excellent resistance to erosion in flowing
seawater at velocities up to 130 ft/sec (40 m/sec), with negligible impact on the material. Abrasive particles, such as sand, have minimal effect on corrosion.
Resilience Against Hydrogen Embrittlement
Titanium shows no significant hydrogen absorption when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only under specific conditions:
- pH levels < 3 or > 12
- Temperatures above 176°F (80°C)
- Presence of a hydrogen generation mechanism, such as a galvanic couple or impressed current.
Bio-corrosion Resistance
Titanium alloys exhibit an extraordinary resistance to all types of microbiologically influenced corrosion. Notably, they are non-toxic to marine life, which can result in biofouling in seawater environments. This issue can be controlled effectively through chlorination or by increasing the water velocity through the heat exchanger.
Corrosion Fatigue
Remarkably, titanium maintains its fatigue performance even in seawater, unlike many other materials. The fatigue endurance limits and fatigue *** growth rates of titanium remain consistent whether tested in air or seawater, making it an ideal choice for marine applications.
Galvanic Corrosion
In the galvanic series, titanium is positioned near the noble end, close to stainless steels, typically functioning as the cathode when paired with other metals. This positioning means titanium is resistant to galvanic corrosion, although it can accelerate the corrosion of the other metal. When coupled with more noble metals like graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod stands out for its remarkable fatigue properties, showing no degradation in the presence of seawater. Whether tested in air or seawater, its fatigue endurance limits and fatigue *** growth rates remain unchanged, ensuring durability and reliability.
Weldability
The CP2 Grade Titanium Rod is highly weldable, provided the necessary precautions are taken. Given titanium's reactivity, it is crucial to use an inert gas shield on both the outer and inner surfaces of the rod. Additionally, the material must be free from any grease or oil contamination to ensure a successful weld.
Grade 2 Titanium Rod is generally welded using manual or automatic TIG welding, with or without filler wire. To minimize the heat-affected zone, low heat input should be employed. Typically, post-weld heat treatment is not required for Titanium Rod.
