Titanium Grade 23 As Printed vs Grade 23-O
Titanium · Grade 23 temper comparison
Grade 23 As Printed and Grade 23-O are two conditions of the same titanium grade, Grade 23: As Printed (as built (as printed)) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. Grade 23 As Printed is the stronger of the two: yield strength 1,050 MPa (152 ksi) against 850 MPa (123 ksi) for Grade 23-O, about 24% more; tensile strength follows at 1,150 MPa (167 ksi) vs 930 MPa (135 ksi). In exchange, Grade 23-O is the more ductile: elongation 15% versus 9% for Grade 23 As Printed, and Grade 23 As Printed is harder (38 HRC vs 33 HRC). Grade 23-O runs hotter in service (350°C vs 300°C continuous).
Grade 23 As PrintedChoose it when strength drives the design.
Grade 23-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Grade 23 As Printed vs Grade 23-O: 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.

Grade 23 As Printed vs Grade 23-O — frequently asked
Is Grade 23 As Printed stronger than Grade 23-O?
Yes. Grade 23 As Printed has a typical yield strength of 1,050 MPa (152 ksi) against 850 MPa (123 ksi) for Grade 23-O — about 24% more. Tensile strength is 1,150 MPa (167 ksi) vs 930 MPa (135 ksi).
Which condition does FabDigit quote by default, As Printed or O?
O is the default Grade 23 condition in the FabDigit quote flow. 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.
When should I choose Grade 23 As Printed over Grade 23-O?
Pick Grade 23 As Printed when strength drives the design. Pick Grade 23-O when the part is bent, formed or impact-loaded, or when the part sees heat.
