HEAT TREATMENT
- For applications requiring high hardness, tensile strength, and fatigue resistance, our titanium rods can be annealed at temperatures between 1,700-1,900°F (927 - 1,038°C).
The DAXUN 6-4™ Grade 5 alloy offers versatile heat treatment options to suit various industrial needs. - 1. Anneal: Heat at 1,275 -1,400°F (691 - 760°C) for ½ to 2 hours, then cool in air or furnace.
- 2. Stress Relief Anneal: Heat at 1,000 -1,200°F (538 - 649°C) for 1 to 8 hours, then cool in air or furnace.
- 3. Solution Heat Treat: Heat at 1,675 -1,750°F (913 - 954°C) for 1 hour, then quench in water.
- 4. Aging: Heat at 975 -1,025°F (524 - 552°C) for 4 to 8 hours, then cool in air.
In the solution-treated and aged condition, rapid quenching of small sections yields peak properties. Larger sections or delayed quenching may lead to suboptimal properties.
HARDNESS
Typically, the hardness in the annealed condition is Rockwell C 30-34, and it reaches about Rockwell C 35-39 in the solution-treated and aged condition.
Forgeability/Formability
- Ti-6Al-4V, Grade 5 alloy bar is optimally forged at 1,750°F (954°C) with a final forging temperature of 1,450°F (788°C). For best results, a minimum 35% reduction is recommended.
- Ti-6Al-4V, Grade 5 alloy bar is challenging to form at room temperature, even when annealed. For severe forming operations like bending or stretching, perform them 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 efficiently machined using the same techniques as for austenitic stainless steel but requires slow speeds, high feeds, robust tooling, and copious non-chlorinated cutting fluids.
Weldability
The Ti-6Al-4V, Grade 5 alloy rod offers exceptional weldability, whether annealed or solution aged. To ensure optimal results, it is imperative to shield the material from contamination by oxygen, nitrogen, and hydrogen. Fusion welding should be performed within an inert gas-filled chamber or with inert gas protection for the molten metal and adjacent heated zones, using a tail shield. Spot, seam, and flash welding can also be executed effectively without a protective atmosphere, maintaining the integrity and quality of the weld.
Special Considerations
Ti-6Al-4V, Grade 5 titanium alloy rods can suffer contamination from hydrogen due to improper pickling, and from oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such contamination leads to decreased ductility, impacting notch sensitivity and forming characteristics adversely.

High-Quality Grade 2 Titanium Rod
Exceptional Corrosion Resistance
Avoid using titanium with strong reducing acids, fluoride solutions, pure oxygen, or anhydrous ***.
General Corrosion Resistance
Table 1 details the general corrosion rates for Grade 2 titanium across a variety of media. CP titanium exhibits remarkable resistance to corrosion in numerous environments, including:
- Seawater and Brines
- Inorganic Salts
- Moist *** Gas
- Alkaline Solutions
- Oxidizing Acids
- Organics and Organic Acids
- Sulfur Compounds
Superior Crevice Corrosion Resistance
CP titanium offers exceptional resistance to crevice corrosion in saline solutions, outperforming stainless steels. It remains unaffected by crevice corrosion at temperatures below 80°C (176°F), irrespective of pH, even in highly chlorinated conditions.
Outstanding Stress Corrosion Cracking Resistance
Grade 2 titanium demonstrates excellent resistance to stress corrosion cracking (SCC) in hot chloride solutions and is immune to SCC in seawater.
Impressive Erosion Corrosion Resistance
Titanium exhibits superior resistance to erosion in flowing
seawater, even at velocities up to 130 ft/sec (40 m/sec), with minimal impact on the material integrity. The presence of abrasive particles, like sand, poses only a slight effect on corrosion.
Minimized Hydrogen Embrittlement Risk
Titanium does not significantly absorb hydrogen when exposed to seawater, even at elevated temperatures. Hydrogen absorption typically occurs only under the following conditions:
- pH is < 3 or > 12
- Temperature exceeds 176°F (80°C)
- Presence of a hydrogen-generating mechanism, such as a galvanic couple or impressed current.
Resilient Bio-Corrosion Resistance
Titanium alloys exhibit exceptional resilience against all forms of microbiologically influenced corrosion. Their non-toxic nature towards marine life can lead to biofouling in seawater, which can be effectively mitigated through chlorination or by enhancing the water flow rate within heat exchangers.
Corrosion Fatigue
Unlike numerous other materials, titanium maintains its fatigue performance in the presence of seawater. Both the fatigue endurance limits and fatigue *** growth rates remain consistent whether the tests are conducted in air or seawater.
Galvanic Corrosion
In the galvanic series, titanium is positioned towards the noble end near 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 like graphite, titanium's passivity is further enhanced.
Fatigue Properties
Grade 2 Titanium Rod stands apart from many materials by not displaying any degradation in fatigue properties due to seawater exposure. The fatigue endurance limits and fatigue *** growth rates are consistent whether in air or seawater.
Weldability
The CP2 Grade Titanium Rod boasts exceptional weldability, provided adequate precautions are observed. Due to titanium's reactivity, an inert gas shield must protect both the outer and inner surfaces of the rod, ensuring the material is free from any grease or oil contamination.
Typically, Grade 2 Titanium Rod is welded using manual or automatic TIG welding, with or without filler wire. Employing low heat input is crucial to minimize the heat-affected zone's size. Post-weld heat treatment is generally not required for Titanium Rod.
