ASTM B381 Titanium Grade 9 Flanges are low weight, high strength titanium alloy flanges fabricated from Ti-3Al-2.5V (UNS R56320). Good corrosion resistance, moderate strength and excellent weldability make these flanges suitable for aerospace, marine, chemical processing and oil & gas industries. Grade 9 Titanium Forged Flanges are available in different styles like slip-on, weld neck, blind and threaded and are extensively used in applications where the need of durability and weight reduction is there.
Introduction to ASTM B381 Titanium Grade 9 Flanges
ASTM B381 Titanium Grade 9 Flanges are a good choice for reliable performance if you need strength, corrosion resistance and weight savings all at the same time. These Ti-3Al-2.5V alloy flanges combine the benefits of the commercially pure titanium and of the alloyed titanium grades.
We offer a wide range of Titanium Gr 9 Pipe Flanges that are manufactured as per the international standards like ASTM B381 and ASME SB381. These flanges are typically used in harsh environments where corrosion or weight can cause stainless steel or carbon steel to fail.
As an experienced ASME SB381 Ti Grade 9 Flange Manufacturer, we strive to offer precision forged products that meet rigorous industrial standards and ensure consistent quality.

What is Titanium Grade 9 (Ti-3Al-2.5V)?
UNS R56320 Titanium Flanges are also called Titanium Grade 9. It is an alpha-beta alloy containing 3% aluminum and 2.5% vanadium. It is stronger than grades of pure titanium such as Grade 2, but easier to fabricate and weld than the higher strength alloys.
Key Characteristics:- Great strength to weight ratio
- Superior corrosion resistance (especially in sea water)
- Good cold workability
- Excellent weldability
- Average strength, Grade 5
Due to these properties, Titanium Alloy Grade 9 Flanges are widely used in applications where performance and cost are equally important.
