ASTM B381 Titanium Grade 23 flanges are forged titanium alloy flanges made from Ti-6Al-4V ELI (Extra Low Interstitial) material. They offer enhanced ductility, fracture toughness, and corrosion resistance, making them ideal for critical applications such as medical implants, aerospace components, and high-performance piping systems.
What is UNS R56401 Titanium Flange?
UNS R56401 refers to Titanium Grade 23 (Ti-6Al-4V ELI) , a refined version of Grade 5 titanium with lower interstitial elements such as oxygen and iron. This composition enhances:
- Ti 6Al-4V ELI Weld Neck Flanges – Ideal for high-pressure systems
- Grade 23 Titanium Blind Flanges – Used to seal pipeline ends
- Slip-On Flanges
