HEAT TREATMENT
- For applications requiring high hardness, tensile strength, and fatigue resistance, annealing can be done at temperatures between 1,700-1,900°F (927-1,038°C).
The 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, followed by air or furnace cooling
- 2. Stress Relief Anneal: 1,000-1,200°F (538-649°C), 1 to 8 hours, followed by air or furnace cooling
- 3. Solution Heat Treat: 1,675-1,750°F (913-954°C), 1 hour, followed by water quenching
- 4. Aging: 975-1,025°F (524-552°C), 4 to 8 hours, followed by air cooling
Optimal properties in the solution treated and aged condition are achieved through rapid quenching of smaller sections, while larger sections or delayed quenching may result in suboptimal properties.
HARDNESS
Typical hardness ranges from Rockwell C 30-34 in the annealed condition to Rockwell C 35-39 in the solution and aged condition.
Forgeability/Formability
- The Ti-6Al-4V, Grade 5 alloy bar is forgeable 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.
- Forming the Ti-6Al-4V, Grade 5 alloy bar at room temperature is challenging, even when annealed. Severe forming operations 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 achieved through creep forming within the 1,000-1,200°F (538-649°C) range.
Machinability
The Ti-6Al-4V, Grade 5 alloy bar can be machined using techniques for austenitic stainless steel, employing slow speeds, high feed rates, sturdy tools, and ample non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod offers excellent weldability, whether in the annealed condition or in the solution and partially aged state, with aging executed during post-weld heat treatment. To maintain its superior properties, it is crucial to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding can be performed within an inert gas-filled chamber or using an inert gas to protect the molten metal and adjacent heated zones, alongside a tail shield. Additionally, 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 contamination with hydrogen during improper pickling, and with oxygen, nitrogen, and carbon during forging, heat treating, brazing, among other processes. This contamination can lead to a reduction in ductility, negatively impacting notch sensitivity and forming characteristics.

Grade 2 Titanium Rod: Excellence in Quality and Performance
Outstanding Corrosion Resistance
Usage Caution: Avoid exposure to strong reducing acids, fluoride solutions, pure oxygen, or anhydrous *** to maintain titanium integrity.
Comprehensive General Corrosion Resistance
Grade 2 titanium's general corrosion rates in various media are detailed in Table 1. CP titanium demonstrates robust resistance in diverse environments, including:
- Resilient against Seawater and Brines
- Durable in Inorganic Salts
- Withstands Moist *** Gas
- Stable in Alkaline Solutions
- Resistant to Oxidizing Acids
- Compatible with Organics and Organic Acids
- Resistant to Sulfur Compounds
Exceptional Crevice Corrosion Resistance
In salt solutions, CP titanium outperforms stainless steels in terms of crevice corrosion resistance, with no crevice corrosion below 80°C (176°F) regardless of pH, even in highly chlorinated conditions.
Immunity to Stress Corrosion Cracking
Grade 2 titanium excels in resisting SCC in hot chloride solutions and remains unaffected by sec in seawater.
Superb Erosion Corrosion Resistance
Titanium's excellent resistance to erosion in flowing
seawater at velocities up to 130 ft/sec (40 m/sec) is notable, with minimal impact from abrasive particles like sand.
Negligible Hydrogen Embrittlement
Titanium does not significantly absorb hydrogen when exposed to seawater, even at higher temperatures. Hydrogen absorption is rare and occurs only when these three conditions are met:
- Extremes of pH (< 3 or > 12)
- Elevated temperatures (above 176°F/80°C)
- Presence of a hydrogen generation mechanism (e.g., galvanic couple or impressed current).
Resilience against Bio-corrosion
Titanium alloys showcase a remarkable resistance to all forms of microbiologically influenced corrosion. Given their non-toxicity towards marine organisms, biofouling can occur in seawater, but this can be effectively mitigated through chlorination or by increasing the water velocity through heat exchangers.
Corrosion Fatigue
Titanium stands out among materials for its consistent fatigue performance, even in seawater. Fatigue endurance limits and fatigue *** growth rates remain unchanged whether tested in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is positioned near the noble end, close to stainless steels, and generally acts as the cathode when paired with other metals. Consequently, titanium remains unaffected by galvanic corrosion but can accelerate corrosion in the other metal. When coupled with noble metals like graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod retains its excellent fatigue properties, even in seawater conditions. Fatigue endurance limits and fatigue *** growth rates remain consistent whether tested in air or seawater.
Weldability
CP2 Grade Titanium Rod offers exceptional weldability when proper precautions are taken. Due to titanium's reactivity, an inert gas shield must protect both the OD and ID of the rod, and the material must be free from grease or oil contamination.
Grade 2 Titanium Rod is commonly welded using manual or automatic TIG welding, with or without filler wire. A low heat input is recommended to minimize the heat-affected zone. Typically, post-weld heat treatment is not necessary for Titanium Rod.
