Grade 2 Titanium Rod, also called T40 Titanium Rod, is a commercially pure titanium product offering moderate strength (~345 MPa), high ductility, and superior corrosion resistance. It retains formability and weldability across a wide temperature range (–184 °C to 540 °C), making it ideal for high-performance structural and fluid-transfer components. It is commonly used in chemical processing systems, heat exchangers, marine desalination units, and medical implants. Specific uses include osseointegrated dental implants, reactor tubing, condenser shells, and high-ductility biomedical pins. Grade 2's balance of strength and biocompatibility makes it a critical material in tissue engineering and biomedical research. In material science, its response to severe plastic deformation via ECAP and rolling has yielded ultrafine-grained rods with strength approaching that of Ti‑6Al‑4V, fostering innovations in cost-effective, formable titanium biomaterials. Its broad applicability and tunable mechanical performance solidify its industrial and scientific relevance.
