Duplex S31803 is the most commonly used commercially pure (CP) titanium, offering an excellent combination of corrosion resistance, strength, and ductility. It has moderate strength compared to titanium alloys but stands out due to its superior formability, weldability, and toughness, making it highly versatile across different industries.

This grade performs exceptionally well in environments containing chlorides, seawater, and a wide range of oxidizing media, where many other metals fail. Its biocompatibility also makes it suitable for medical and pharmaceutical applications.
