Titanium Grade 23 As Printed vs Grade 23 Stress Relieved

Titanium · Grade 23 temper comparison

Grade 23 As Printed and Grade 23 Stress Relieved are two conditions of the same titanium grade, Grade 23: As Printed (as built (as printed)) versus Stress Relieved. 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 890 MPa (129 ksi) for Grade 23 Stress Relieved, about 18% more; tensile strength follows at 1,150 MPa (167 ksi) vs 970 MPa (141 ksi). In exchange, Grade 23 Stress Relieved is the more ductile: elongation 13% versus 9% for Grade 23 As Printed, and Grade 23 As Printed is harder (38 HRC vs 34 HRC). Grade 23 Stress Relieved runs hotter in service (350°C vs 300°C continuous).

Grade 23 As PrintedChoose it when strength drives the design.

Grade 23 Stress RelievedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

Grade 23 As Printed vs Grade 23 Stress Relieved — frequently asked

Is Grade 23 As Printed stronger than Grade 23 Stress Relieved?

Yes. Grade 23 As Printed has a typical yield strength of 1,050 MPa (152 ksi) against 890 MPa (129 ksi) for Grade 23 Stress Relieved — about 18% more. Tensile strength is 1,150 MPa (167 ksi) vs 970 MPa (141 ksi).

Which condition does FabDigit quote by default, As Printed or Stress Relieved?

O is the default Grade 23 condition in the FabDigit quote flow (neither As Printed nor Stress Relieved). 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 Stress Relieved?

Pick Grade 23 As Printed when strength drives the design. Pick Grade 23 Stress Relieved when the part is bent, formed or impact-loaded, or when the part sees heat.
