Titanium Gr 23 Manufacturer, Supplier and Stockist

HOME → Titanium Alloy → Titanium Grade 23

Titanium grade 23 is requested by aerospace engineers as well as surgeons whenever there is a need for a titanium element highly resistant to fracture and crack propagation. Titanium grade 23 is the same as Ti-6Al-4V ELI, which is considered the better and stronger relative of Grade 5 titanium, and this titanium is given the UNS number R56401. Grade 23 is the extra-low-interstitial (ELI) version of Grade 5, offering improved ductility and fracture toughness at a marginally lower strength, but it is still able to withstand fractures easily. It is available in different forms like plate, round bar and wire at the Sachin Steel Centre in the city of Mumbai and is also certified for ASTM B265, ASTM B348, and ASTM F136.

Frequently Asked Questions

What is titanium Gr 23?

Titanium Gr 23 is a Ti-6Al-4V ELI alloy with reduced oxygen, carbon, nitrogen, and iron. It combines high strength, corrosion resistance, ductility, and biocompatibility.

What is the difference between Titanium Gr 23 and Grade 5?

Titanium grade 23 is the ELI version of grade 5, with lower interstitial limits. Grade 23 provides improved ductility and fracture toughness for demanding applications.

Is Titanium Gr 23 the same as Ti-6Al-4V ELI and UNS R56401?

Yes. Titanium Gr 23 is commonly designated Ti-6Al-4V ELI and UNS R56401. It is also known as grade 5 ELI titanium.

What does ELI mean in titanium?

ELI means Extra Low Interstitials. Ti 6Al 4V ELI titanium has lower limits for elements such as oxygen, nitrogen, carbon, and iron.

Is titanium Gr 23 used for medical implants?

Yes. Titanium Gr 23 is widely used as medical-grade titanium and implant-grade titanium for orthopaedic, dental, and surgical implant applications.

Which ASTM standards cover titanium gr 23?

ASTM F136 covers wrought titanium alloy for surgical implant applications. ASTM B265 and ASTM B348 cover titanium Gr 23 plate and bar, respectively.

Can titanium Gr 23 be welded, machined, and heat treated?

Yes. Titanium Gr 23 can be welded, machined, and heat treated using appropriate procedures. Controlled processing helps maintain its mechanical properties and surface quality.

What forms, sizes, and thicknesses are available, and can it be cut to size?

Titanium Gr 23 plate, titanium Gr 23 round bar, and titanium Gr 23 wire are available in various sizes and can be cut to specified dimensions.
