TITANIUM GRADE 11 FITTINGS

EXPORTERS, STOCKIST & MANUFACTURER OF TITANIUM GRADE 11 FITTINGS

Titanium Grade 11 is a high-strength, corrosion-resistant alloy primarily composed of titanium and small amounts of palladium. It is also known as Titanium 0.15% Palladium, referring to its palladium content. Titanium Grade 11 is part of the commercially pure titanium grades, which are characterized by their excellent corrosion resistance, high strength, and low density.
Fittings made from Titanium Grade 11 are commonly used in various industries, including chemical processing, aerospace, marine engineering, and medical applications, where corrosion resistance and biocompatibility are essential. The addition of palladium enhances the alloy’s corrosion resistance, especially in reducing environments.

Titanium Grade 11 fittings are often chosen for their combination of mechanical properties and corrosion resistance, making them suitable for challenging environments where other materials might fail. These fittings can include items like pipes, flanges, elbows, tees, and other components used in piping systems. The alloy is also known for its excellent weldability, allowing for easy fabrication and installation.
In summary, Titanium Grade 11 fittings are a reliable choice for applications requiring high corrosion resistance, strength, and biocompatibility, making them valuable in various industries and critical environments.
