Grade 5 Titanium / Ti-6Al-4V

Grade 5 is one of the most widely recognized titanium alloys and is designated UNS R56400 under ASTM B861. ASTM identifies Grade 5 as a titanium alloy containing approximately 6% aluminum and 4% vanadium.

The alloy combines:

• High strength-to-weight ratio
• Good corrosion resistance
• Low density
• Good fatigue performance
• Good resistance to many industrial environments
• Suitable mechanical performance for demanding applications

For international procurement, the material can be identified as:

Grade 5 Titanium = Ti-6Al-4V = UNS R56400

Excellent Strength-to-Weight Ratio

Ti-6Al-4V provides high mechanical strength while maintaining relatively low density compared with many conventional engineering metals. This can help reduce component weight in compact piping and equipment systems.

Good Corrosion Resistance

Grade 5 titanium provides good corrosion resistance in many industrial environments. It can be considered for selected chemical piping applications where resistance to corrosion and long service life are important.

Seamless Tube Construction

The seamless manufacturing process eliminates a longitudinal welded seam and provides a continuous tube structure. This makes seamless tubing suitable for applications requiring consistent geometry and reliable service performance.

Compact Precision Dimensions

The 5mm OD × 4mm ID configuration provides a small-diameter flow passage with an approximate 0.5mm wall thickness, making it suitable for compact piping, instrumentation and specialized equipment.

Lightweight Construction

Titanium's relatively low density can help reduce the overall weight of piping assemblies and equipment, which can simplify handling, transportation and installation.

Elevated-Temperature Service Capability

ASTM B861 covers titanium and titanium alloy seamless pipe for general corrosion-resistant and elevated-temperature service. Actual operating temperature limits depend on alloy condition, design requirements and the specific application.

The ASTM B861 Grade 5 Titanium Seamless Tube can be considered for a variety of demanding industrial applications, including:

• Chemical piping systems
• Chemical processing equipment
• Laboratory piping
• Instrumentation tubing
• Corrosive fluid transfer systems
• Process equipment
• Heat-transfer equipment
• Specialized industrial piping
• Marine-related equipment
• Lightweight process assemblies

For chemical piping systems, material selection should be based on the actual process conditions rather than corrosion resistance alone.
