Standards

What ASTM F1472 covers, how it differs from F136 ELI, and how ASTM F620 forgings inherit the UNS of their source implant spec.

Sourcing titanium for Canadian pressure vessels and heat exchangers: how ASME adopts ASTM as SB specs, where CRN fits, and what EN 10204 certs mean.

How Grade 5 (Ti-6Al-4V) lines up across AMS, ASTM, UNS, Werkstoff and TC4, why AMS 4928 is not AMS 4911, and what the EN 10204 cert chain means.

Compare ASTM, UNS, Werkstoff, French NF and JIS titanium grade names, and see which standard belongs on your PO.

AMS 4928 titanium bar: how the Ti-6Al-4V aerospace spec differs from ASTM B348 Grade 5 and AMS 4911, with chemistry, strength limits and how to order.

ASTM F136 Ti-6Al-4V ELI bar and wire for implant-grade machining: what ELI means, F136 vs F1472, and how to specify tolerance, finish and certs. RFQ.

ASTM F67 CP titanium bar, Grades 1-4, precision centerless ground to ±0.0127 mm, with EN 10204 3.1 MTC and heat traceability. How to specify and RFQ.

Check four things on a titanium mill test certificate: the heat number matches the marking on the metal, the chemistry sits inside the ordered specification, the mechanical results meet the specification minimums, and the document type is the one ordered, normally EN 10204 type 3.1 for process equipment. The way to verify titanium quality is

Side-by-side ASTM F136 vs F67: chemistry, mechanical minimums, Grade 23 ELI vs CP titanium, and which implant standard to cite on an RFQ.
