Titanium Grade 23 Scrap Buyer and Seller
Grade 23 scrap is mostly offcuts and turnings from implant and instrument makers. Its premium over Grade 5 exists only on paper: without the certificates, an analyser sees Ti-6Al-4V. Mipra Steel trades it with its documents attached.
Sell Titanium Grade 23 Scrap
Tell us the form, weight, location and whether the material is traceable to ASTM F136 or AMS 4930/4931 certificates. Keep certified and uncertified material in separate lots. We review incoming enquiries and respond with relevant next steps.

Melters can state whether they need certified ELI material or accept it as Grade 5, the quantity and accepted forms.
What Is Titanium Grade 23?
ELI stands for extra low interstitials. ATI describes its 6-4 ELI as a higher-purity version of Ti-6Al-4V with lower oxygen, carbon and iron, produced by vacuum arc melting followed by a second vacuum arc remelt. Fort Wayne Metals adds that tighter control of iron and oxygen improves ductility and fracture toughness. Aluminium and vanadium are the same as in Grade 5.
Uses listed by producers include orthopaedic implants and surgical instruments, marine and cryogenic parts, and some aerospace components. Two UNS numbers are in use: R56401 for the ASTM F136 surgical-implant specification and R56407, which ATI uses for its Grade 23 product.
For scrap, the key point is that the difference between Grade 23 and Grade 5 lies in oxygen and other light elements that a handheld analyser does not measure. A lot can only be sold as Grade 23 with paperwork tying it to ELI material; otherwise it trades as Grade 5.
Grade 23 is listed with our titanium grades.

| Nitrogen | N | 0.05 max |
| Hydrogen | H | 0.012 max (0.015 for material 0.813 mm and under) |
| UNS | R56401 (ASTM F136); R56407 (ATI Grade 23) |

Telling Grade 23 from Grade 5
| Evidence | What it shows |
|---|---|
| Analyser reading: Al about 6%, V about 4% | Ti-6Al-4V: Grade 5 or Grade 23, not which |
| Certificate to ASTM F136 or AMS 4930/4931 | Grade 23, if the material is traceable to it |
| Laboratory oxygen at or below 0.13% | Consistent with ELI |
| Implant or instrument maker as source, with records | Supports Grade 23 |
Without records, sell the lot as Grade 5. Mixing certified Grade 23 into uncertified material removes the reason a melter would pay for it.

Titanium Grade 23 FAQ
What is the difference between Grade 5 and Grade 23 titanium?
Both are Ti-6Al-4V. Grade 23 (ELI) has lower limits on oxygen and other interstitial elements, giving better ductility and fracture toughness.
What is the UNS number for Grade 23?
UNS R56401 is used for ASTM F136 surgical-implant material; R56407 is also used for Grade 23 product.
Can an XRF analyser tell Grade 23 from Grade 5?
No. The difference is in oxygen and other light elements; certificates or a laboratory analysis decide the grade.
What is Grade 23 used for?
Surgical implants and instruments, and marine, cryogenic and some aerospace components.
Which HS code applies to titanium Grade 23 scrap?
Heading 8108.30, titanium waste and scrap.
