What Is TA2 Titanium?
TA2 is Commercially Pure Titanium Grade 2, one of the most widely used titanium materials in industrial valve manufacturing.
Its naturally formed oxide film continuously protects the metal surface, giving it exceptional resistance to corrosion without requiring additional coatings.
Material Advantages
- Excellent seawater resistance
- Outstanding chloride corrosion resistance
- Superior resistance to oxidizing chemicals
- Excellent weldability
- High strength-to-weight ratio
- Non-magnetic
- Long service life
- Excellent fatigue resistance
Compared with stainless steel, TA2 provides significantly longer service life in marine and chemical environments.
