Titanium Ti-6Al-4V ELI (Grade 23) AM Powder-HIP vs Ti-6Al-4V ELI (Grade 23) AM Powder-STA
Titanium · Ti-6Al-4V ELI (Grade 23) AM Powder temper comparison
Ti-6Al-4V ELI (Grade 23) AM Powder-HIP and Ti-6Al-4V ELI (Grade 23) AM Powder-STA are two conditions of the same titanium grade, Ti-6Al-4V ELI (Grade 23) AM Powder: HIP (hot isostatic pressed) versus STA (solution treated and aged). The chemistry is identical, so every difference below comes from the condition. Ti-6Al-4V ELI (Grade 23) AM Powder-STA is the stronger of the two: yield strength 1,080 MPa (157 ksi) against 880 MPa (128 ksi) for Ti-6Al-4V ELI (Grade 23) AM Powder-HIP, about 23% more; tensile strength follows at 1,170 MPa (170 ksi) vs 970 MPa (141 ksi). In exchange, Ti-6Al-4V ELI (Grade 23) AM Powder-HIP is the more ductile: elongation 17% versus 10% for Ti-6Al-4V ELI (Grade 23) AM Powder-STA, and Ti-6Al-4V ELI (Grade 23) AM Powder-STA is harder (355 HB vs 330 HB). On the shop floor, Ti-6Al-4V ELI (Grade 23) AM Powder-HIP welds better (very good vs good).

Ti-6Al-4V ELI (Grade 23) AM Powder-HIP vs Ti-6Al-4V ELI (Grade 23) AM Powder-STA: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all titanium grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

Ti-6Al-4V ELI (Grade 23) AM Powder-HIP vs Ti-6Al-4V ELI (Grade 23) AM Powder-STA — frequently asked
Is Ti-6Al-4V ELI (Grade 23) AM Powder-STA stronger than Ti-6Al-4V ELI (Grade 23) AM Powder-HIP?
Yes. Ti-6Al-4V ELI (Grade 23) AM Powder-STA has a typical yield strength of 1,080 MPa (157 ksi) against 880 MPa (128 ksi) for Ti-6Al-4V ELI (Grade 23) AM Powder-HIP — about 23% more. Tensile strength is 1,170 MPa (170 ksi) vs 970 MPa (141 ksi).
Which condition does FabDigit quote by default, HIP or STA?
SR is the default Ti-6Al-4V ELI (Grade 23) AM Powder condition in the FabDigit quote flow (neither HIP nor STA). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, Ti-6Al-4V ELI (Grade 23) AM Powder-HIP or Ti-6Al-4V ELI (Grade 23) AM Powder-STA?
Ti-6Al-4V ELI (Grade 23) AM Powder-HIP, by a small margin. Both rate poor for machinability — 22/100 against 17/100 for Ti-6Al-4V ELI (Grade 23) AM Powder-STA; for welding the order is Ti-6Al-4V ELI (Grade 23) AM Powder-HIP first (very good, 75/100) then Ti-6Al-4V ELI (Grade 23) AM Powder-STA (good, 60/100).
