Product Overview
Introduction To Titanium Grade 7 NB / Ti-0.2Pd / UNS R52400
MOKSH TUBES & FITTINGS LLP is a leading manufacturer, supplier, exporter, importer, and stockist of a wide range of Titanium Grade 7 NB products including Pipes & Tubes, Pipe Fittings, Flanges, Fasteners, Sheets & Plates, Coils, Wires, Bars, Forgings, Custom Components, and other hard-to-find titanium alloy products tailored to your exact requirements.
Titanium Grade 7 NB (UNS R52400), also known as Ti-0.2Pd, is a corrosion-resistant, alpha-phase titanium alloy that offers the same mechanical properties as Grade 2, but with enhanced corrosion resistance due to the addition of palladium (0.12–0.25%). This makes it one of the most corrosion-resistant titanium grades available, especially in reducing and mildly oxidizing environments such as hydrochloric and sulfuric acid.
Renowned for its excellent weldability, ductility, and formability, Titanium Grade 7 NB is ideal for industries that operate in aggressive chemical environments and demand both longevity and performance.
