Marking and packing are traceability, not logistics Once bar leaves the rack, the only thing keeping the certificate attached to the metal is what is written on the piece and how the lot was separated. Buyers who run incoming inspection to an implant or pressure specification treat these as acceptance fields, not shipping preferences. What […]

See when filling lines handling hypochlorite, chlorides or acids need titanium wetted parts, which grades apply and what to state in the RFQ.

Grade 23 titanium is Ti-6Al-4V ELI, the extra low interstitial version of the Ti-6Al-4V alloy. ELI means the melt is held to tighter oxygen and iron limits than Grade 5, and under the ASTM B-series to a tighter nitrogen limit as well. Those interstitials are what make Ti-6Al-4V notch sensitive, so cutting them buys fracture

Field-by-field RFQ checklist for medical titanium bar: F67, F136 and F1472 callouts, interstitials, traceability, NDT and document pack.

Neutral titanium vs Inconel guide for chemical, marine and process service: compare temperature, weight, corrosion and cost before quoting.

How to choose commercially pure titanium Grade 1, 2, 3 or 4 by service, strength and formability, with the standard, form and certificate to order against.

How to specify and verify grain size (ASTM E112) and hydrogen content on medical titanium bar RFQs, the two lab criteria that decide incoming acceptance.

Grade 2 is the grade you specify when a part has to survive a medium. Grade 5 is for parts that carry load. Once you know which of those two duties governs, the grade is close to settled, and the remaining work is product form, condition and documents. Grade 2 is commercially pure titanium, UNS

Grade 5 and Grade 23 are the same Ti-6Al-4V alloy, but Grade 23 is the extra-low-interstitial (ELI) version, with tighter oxygen and iron limits. Grade 5 is slightly stronger (895 MPa minimum tensile against 828 MPa for Grade 23) and cheaper. Grade 23 trades that small amount of strength for substantially higher fracture toughness, better

For seawater piping, 316L stainless steel is the wrong default. Its pitting resistance is too low for chloride immersion, so it pits and crevice-corrodes, usually at welds, deposits and stagnant zones. The two materials that actually survive seawater are copper-nickel and titanium. Copper-nickel (90/10 and 70/30) is the proven, biofouling-resistant choice for moderate-velocity piping. Titanium
