Commercially Pure Titanium Grade 2 (TA2)
Titanium Grades 1 through 4 are unalloyed and classified as Commercially Pure (CP) Titanium. Among these, Grade 2 (TA2) is one of the widely used due to its balanced strength, ductility, and corrosion resistance.
Compared to steel, titanium is 30% stronger yet nearly 50% lighter, making it ideal for high-performance applications. While aluminum is lighter, titanium offers superior strength retention and corrosion resistance, making it indispensable in industries such as aerospace, medical, marine, and military.
Key Specifications of TA2 Titanium
TA2 titanium is defined by several international standards, including:
AMS 4902F – Sheet, strip, and plate (annealed)
AMS 4941C – Welded tubing (annealed)
AMS 4942C – Seamless tubing (annealed)
AMS 4951F – Welding wire
ASTM B265 Gr2, ASTM B338 Gr2, ASTM F67 Gr2
UNS R50400
UK Standard: TA2 (DTD5073)
French Standard: AIR 9182 T-40
Heat Treatment
TA2 is an alpha-beta titanium alloy, and its mechanical properties can be enhanced through heat treatment:
- Solution Treatment
Heat to 980–1000°C to dissolve secondary phases.
Maintain temperature for sufficient time to achieve homogeneity.
- Water Quenching
Rapidly cool in water to retain a uniform microstructure.
- Aging Treatment
Reheat to 450–550°C to precipitate strengthening phases.
Improves hardness and strength while maintaining corrosion resistance.
Proper heat treatment ensures high strength, fatigue resistance, and structural stability, making TA2 suitable for demanding applications.

Welding and Processing of TA2 Titanium
Welding Methods
Argon Arc Welding (TIG/GTAW)
- Preferred method for TA2 due to high-quality welds.
- Requires pure argon shielding to prevent contamination (oxygen/nitrogen absorption weakens welds).
- Use TA2-grade filler wire for optimal compatibility.
Laser & Electron Beam Welding
- Suitable for precision welding in aerospace and medical applications.
Machining & Forming
Hot Working (800–900°C):
- Forging, extrusion, and rolling improve formability.
- Avoid hydrogen exposure to prevent embrittlement.
Cold Working:
- Possible but requires intermediate annealing (30–60% deformation threshold).
- Annealing at 650–750°C restores ductility.
