Titanium Ti-6Al-4V (Grade 5) AM Powder-ANN vs Ti-6Al-4V (Grade 5) AM Powder-STA
Titanium · Ti-6Al-4V (Grade 5) AM Powder temper comparison
Ti-6Al-4V (Grade 5) AM Powder-ANN and Ti-6Al-4V (Grade 5) AM Powder-STA are two conditions of the same titanium grade, Ti-6Al-4V (Grade 5) AM Powder: ANN (annealed) versus STA (solution treated and aged). The chemistry is identical, so every difference below comes from the condition. Ti-6Al-4V (Grade 5) AM Powder-STA is the stronger of the two: yield strength 1,090 MPa (158 ksi) against 940 MPa (136 ksi) for Ti-6Al-4V (Grade 5) AM Powder-ANN, about 16% more; tensile strength follows at 1,180 MPa (171 ksi) vs 1,030 MPa (149 ksi). In exchange, Ti-6Al-4V (Grade 5) AM Powder-ANN is the more ductile: elongation 14% versus 10% for Ti-6Al-4V (Grade 5) AM Powder-STA, and Ti-6Al-4V (Grade 5) AM Powder-STA is harder (340 HB vs 320 HB). Ti-6Al-4V (Grade 5) AM Powder-ANN runs hotter in service (400°C vs 350°C continuous).

Ti-6Al-4V (Grade 5) AM Powder-ANN vs Ti-6Al-4V (Grade 5) 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 (Grade 5) AM Powder-ANN vs Ti-6Al-4V (Grade 5) AM Powder-STA — frequently asked
Is Ti-6Al-4V (Grade 5) AM Powder-STA stronger than Ti-6Al-4V (Grade 5) AM Powder-ANN?
Yes. Ti-6Al-4V (Grade 5) AM Powder-STA has a typical yield strength of 1,090 MPa (158 ksi) against 940 MPa (136 ksi) for Ti-6Al-4V (Grade 5) AM Powder-ANN — about 16% more. Tensile strength is 1,180 MPa (171 ksi) vs 1,030 MPa (149 ksi).
Which condition does FabDigit quote by default, ANN or STA?
SR-LPBF is the default Ti-6Al-4V (Grade 5) AM Powder condition in the FabDigit quote flow (neither ANN 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 (Grade 5) AM Powder-ANN or Ti-6Al-4V (Grade 5) AM Powder-STA?
Ti-6Al-4V (Grade 5) AM Powder-ANN, by a small margin. Both rate poor for machinability — 22/100 against 17/100 for Ti-6Al-4V (Grade 5) AM Powder-STA; for welding the order is Ti-6Al-4V (Grade 5) AM Powder-ANN first (good, 65/100) then Ti-6Al-4V (Grade 5) AM Powder-STA (good, 60/100).
