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).
Our DAXUN 6-4™ Grade 5 alloy can undergo various heat treatment processes. - 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 small sections yields optimal properties. Larger section sizes and/or delayed quenching may result in less than optimal properties.
HARDNESS
Typical hardness in the annealed condition is Rockwell C 30-34, and in the solution and aged condition, it is about Rockwell C 35-39.
Forgeability/Formability
- The 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 for optimal properties.
- The Ti-6Al-4V, Grade 5 alloy bar is challenging to form at room temperature, even in the annealed condition. Severe forming operations such as bending or stretching can be performed on annealed material at temperatures up to 1,200°F; (649°C) without affecting mechanical properties. Hot sizing or forming can be accomplished by creep forming in the range of 1,000 - 1,200°F; (538 - 649°C).
Machinability
The Ti-6Al-4V, Grade 5 alloy bar can be machined using austenitic stainless steel machining methods with slow speeds, high feeds, rigid tools, and ample non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod is highly weldable whether in its annealed state or after solution and partial aging. Post-weld heat treatment ensures aging. It's crucial to avoid contamination with oxygen, nitrogen, and hydrogen. Fusion welding should be done in an inert gas-filled chamber or using inert gas to weld the molten metal and adjacent heated zones, utilizing a tail shield. Spot, seam, and flash welding can be performed without needing a protective atmosphere.
Special Considerations
The Ti-6Al-4V, Grade 5 titanium alloy rod is susceptible to hydrogen contamination from improper pickling, and to oxygen, nitrogen, and carbon during forging, heat treating, brazing, etc. Such contamination can reduce ductility, negatively impacting notch sensitivity and forming characteristics.

Premium Grade 2 Titanium Rod
Unmatched Corrosion Resistance
Note: Titanium should be avoided in environments involving strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
Comprehensive General Corrosion Protection
Grade 2 titanium boasts impressive general corrosion rates across diverse media, as detailed in Table 1. Commercially Pure (CP) titanium offers robust corrosion resistance in a wide range of environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Exceptional Crevice Corrosion Resistance
CP titanium excels in resisting crevice corrosion in salt solutions compared to stainless steels. It remains unaffected at temperatures below 80°C (176°F), irrespective of pH, even under highly chlorinated conditions.
Outstanding Stress Corrosion Cracking Resistance
Grade 2 titanium demonstrates superior resistance to stress corrosion cracking (SCC) in hot chloride solutions and is entirely immune to SCC in seawater.
Unrivaled Erosion Corrosion Resistance
Titanium shows exceptional resistance to erosion in flowing
seawater at velocities up to 130 ft/sec (40 m/sec), with negligible impact on the material. The presence of abrasive particles, such as sand, minimally affects corrosion.
Minimal Hydrogen Embrittlement
Titanium does not significantly absorb hydrogen when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only under specific conditions:
- pH levels below 3 or above 12
- Temperatures exceeding 176°F (80°C)
- Existence of a hydrogen generation mechanism, such as a galvanic couple or an impressed current.
Advanced Bio-Corrosion Resistance
Titanium alloys exhibit exceptional resistance to all forms of microbiologically influenced corrosion. Given their non-toxic nature towards marine organisms, biofouling can occur in seawater. However, this can be effectively minimized through chlorination or by increasing the water velocity through the heat exchanger.
Corrosion fatigue
Unlike many other materials, titanium does not suffer a reduction in fatigue performance when exposed to seawater. Both 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, typically acting as the cathode when paired with other metals. Consequently, titanium remains unaffected by galvanic corrosion but can accelerate the corrosion of the coupled metal. When paired with more noble metals, such as graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod stands out as it does not show a decline in fatigue properties in the presence of seawater. Fatigue endurance limits and fatigue *** growth rates are consistent whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod boasts excellent weldability, provided necessary precautions are observed. Due to titanium's reactivity, an inert gas shield must protect both the OD and ID of the rod. The material must be free from any grease or oil contamination.
Grade 2 Titanium Rod is commonly 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, Titanium Rod does not undergo post-weld heat treatment.
