Rajtilak Metal is an ISO certified, globally recognized manufacturer and exporter of premier titanium piping components. Built in accordance with ASTM B363 and ASME/ANSI B16.9 specifications, our fittings deliver unparalleled resistance to oxidizing acids, seawater pitting, and industrial chlorine compounds.
We supply unalloyed commercially pure Grade 2 (UNS R50400 / Werkstoff Nr. 3.7035) and Ti-6Al-4V Grade 5 (UNS R56400) seamless and welded elbows, tees, concentric and eccentric reducers, stub ends, and pipe end caps. Each fitting is supplied with EN 10204 3.1 mill test certificates, complete heat traceability, and 100% PMI testing before seaworthy dispatch.
Our titanium fittings undergo stringent inert gas shielding welding, dimensional calibration, non-destructive testing, and bevel end inspection for critical process lines worldwide.
Engineering Attributes of Commercial Grade 2 Titanium
Understand why international engineering teams specify Grade 2 unalloyed titanium fittings for corrosive chemical processes and weight-sensitive marine infrastructure.
Exceptionally Low Density
At approximately 4.51 g/cm³, titanium weighs nearly 45% less than conventional austenitic stainless steel, reducing structural pipe support requirements on offshore platforms, aerospace systems, and marine superstructures without sacrificing strength.
Protective Stable Oxide Layer
Titanium naturally develops a spontaneous, strongly adherent titanium dioxide (TiO₂) film upon air or moisture contact. This passive layer immediately repairs itself if abraded, yielding superior immunity to chloride stress corrosion and oxidizing acids.
High Strength-to-Weight Ratio
Commercial Grade 2 unalloyed titanium delivers optimal mechanical yield strength (min. 275 MPa) and ductility (20% elongation), ensuring reliable, non-brittle continuous service up to 800°F (427°C) and intermittent operations up to 1000°F (538°C).
