Product Overview
Introducing the TiGrade-23Elite Titanium Alloy Plate — a premium, ultra-low interstitial (ELI) titanium solution engineered for mission-critical applications demanding exceptional fracture toughness, weldability, and fatigue resistance. This plate conforms precisely to ASTM B265 Grade 23 specifications and meets ASME BPVC Section II requirements, making it ideal for certified pressure boundary components in aerospace, medical implant manufacturing, and high-reliability industrial systems. As a leading titanium alloy in the Ti-3Al-2.5V ELI family, it delivers superior ductility and notch sensitivity performance compared to standard Grade 12 or Grade 5 alloys — especially at cryogenic and elevated temperatures.
Manufactured via vacuum arc remelting (VAR) followed by precision hot rolling and stress-relieved annealing, each plate undergoes rigorous metallurgical control and non-destructive testing. A full Mill Test Report (MTR) is included with every shipment, certifying chemical composition, mechanical properties, grain structure, and compliance with ASTM B265 Gr23 and ASME II Part D.

Applications
This ELI titanium plate is widely deployed across regulated industries where reliability cannot be compromised. Key applications include surgical instrument blanks and orthopedic implant substrates (leveraging biocompatibility and Ti-3Al-2.5V ELI’s fatigue resistance), cryogenic tank liners for liquid hydrogen storage, high-cycle hydraulic manifolds in aerospace actuation systems, and corrosion-resistant cladding for nuclear coolant piping. As a high-performance titanium alloy, grade 23 titanium enables weight savings of up to 40% versus stainless steel alternatives — without sacrificing structural integrity or regulatory compliance.
