What are Titanium ASTM B338 Gr 5 Pipes?
Titanium ASTM B338 Gr. 5 Pipes are high-strength titanium alloy pipes made using ASTM B338 standards. This standard covers seamless and welded titanium and titanium alloy pipes intended for condenser and heat exchanger services. Grade 5 titanium (Ti-6Al-4V) is an alpha-beta alloy with excellent mechanical properties and corrosion resistance.
It is widely used where weight savings and strength are crucial. The alloy contains:
These pipes are known for:
- Exceptional strength-to-weight ratio
- Corrosion resistance in seawater and chemical environments
- High-temperature stability

Key Features of ASTM B338 Grade 5 Titanium Alloy Pipes
- High Strength: Titanium Grade 5 has nearly twice the strength of pure titanium.
- Corrosion Resistance: Resists corrosion in various environments, including marine, acidic, and industrial atmospheres.
- Lightweight: Nearly 50% lighter than steel, ideal for weight-sensitive applications.
- Heat Resistance: Performs well at high temperatures (up to 400°C).
- Biocompatibility: Safe for medical and surgical use.
