Titanium is one of the most advanced engineering materials used today — a metal that combines extreme corrosion resistance, exceptional strength-to-weight ratio, biocompatibility, seawater stability, and high-temperature performance.
INOX STEEL INDIA supplies Titanium Welded Tubes in Grade 2 (Commercially Pure) and Grade 5 (Ti-6Al-4V) for demanding industries such as desalination, aerospace, power generation, offshore, chemical processing, heat exchangers, and medical systems.
Our welded tubes are manufactured to ASTM B338 / B862, using high-purity shielding gas, controlled welding parameters, and oxygen-free weld environments to achieve flawless weld integrity.
Titanium tubes are produced by rolling titanium strip/plate and welding it using:
Titanium forms a self-healing oxide layer, making it one of the most corrosion-resistant materials on earth.
