ASTM B338 Gr2 Titanium Pipes, with global supply capabilities and the ability to offer custom sizes, are a perfect solution to industries that need high performance, corrosion-resistant, and durable piping systems.

About Titanium Grade 2 Pipes (UNS R50400)

Titanium Grade 2 Pipes, also known as UNS R50400 and Werkstoff Nr. 3.7035, are commercially pure titanium products widely recognized for their versatility and reliability. Often referred to as the “workhorse” of the titanium industry, this grade offers an excellent combination of corrosion resistance, moderate strength, and high formability. It is stronger than Grade 1 and slightly lower in strength than Grade 3, making it suitable for a broad range of engineering applications. 

These pipes exhibit outstanding resistance to corrosion in harsh environments, including marine conditions, chemical processing plants, and pollution control systems. Unlike traditional steel materials, Titanium Grade 2 is non-magnetic and highly resistant to oxidation and chemical attack, ensuring long service life and minimal maintenance. Its excellent weldability and low impurity content also reduce the risk of cracking during fabrication.

Titanium Grade 2 pipes are commonly used in aerospace, marine, nuclear, and heat exchanger applications due to their high strength-to-weight ratio and durability. They are designed to handle the safe transportation of fluids and gases, often being pressure-rated to prevent leakage. Available in various forms such as seamless and welded, and in different lengths including single random, double random, and cut lengths, these pipes offer flexibility for diverse industrial requirements.

To maintain quality during storage and shipping, Titanium Grade 2 pipes are properly coated, bundled, and protected with end caps and wrapping materials. Their combination of mechanical strength, corrosion resistance, and fabrication ease makes ASTM B338 Gr2 Titanium Pipes & Tubes a dependable choice for critical industrial applications.
