Description
Technical Parameters
Products Description
Gr23 titanium bar, also known as Ti-6Al-4V ELI (Extra Low Interstitial), is the extra-low interstitial variant of Ti-6Al-4V (Gr5) titanium alloy. It has stricter limits on oxygen, hydrogen and nitrogen, delivering superior ductility, fracture toughness and fatigue performance compared with standard Grade 5 titanium bar.
Gr5 (Ti-6Al-4V) is standard titanium alloy. Gr23 (Ti-6Al-4V ELI) has tighter limits on interstitial elements. Gr23 has better toughness, lower notch sensitivity and superior fatigue performance. Gr5 is cheaper for normal industrial use; Gr23 is selected when higher impact / fatigue resistance is required.

FAQ bout Industrial Grade Gr23 Titanium Bar
Frequently Asked Questions
Why Choose Ruihang?
+
-
Ruihang Group is the direct manufacturer with more than 13 years experiences in titanium alloy production. The company mainly produces titanium products with the complete industry chain, including smelting,forging,straightening,rolling,surface treating,testing process. All titanium products comply with AMS, ASTM, MIL, ISO, GB and GJB standards.
Can industrial Gr23 replace medical Gr23 for implant?
+
-
No. Even if chemical composition is similar, industrial grade lacks medical-grade process control, traceability and biocompatibility validation. It is prohibited for human implant use.
Can I get MTR (Material Test Report)?
+
-
Yes, standard MTR with chemical composition and mechanical test data is provided. But industrial grade MTR does not include medical implant certification. Additional UT / NDT can be arranged as buyer's request.
What size ranges are available?
+
-
Round bar diameter: 3mm ~ 75mm. Length: 1000mm, 2000mm or custom cut-to-length. Custom diameters can be produced by forging.
