Titanium VT1-0-ANN vs VT1-0-SR
Titanium · VT1-0 temper comparison
VT1-0-ANN and VT1-0-SR are two conditions of the same titanium grade, VT1-0: ANN (annealed) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. VT1-0-SR is the stronger of the two: yield strength 400 MPa (58 ksi) against 320 MPa (46.4 ksi) for VT1-0-ANN, about 25% more; tensile strength follows at 500 MPa (72.5 ksi) vs 450 MPa (65.3 ksi). In exchange, VT1-0-ANN is the more ductile: elongation 28% versus 18% for VT1-0-SR, and VT1-0-SR is harder (180 HB vs 155 HB).
VT1-0-ANNChoose it when the part is bent, formed or impact-loaded.
VT1-0-SRChoose it when strength drives the design.
VT1-0-ANN vs VT1-0-SR: 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.

VT1-0-ANN vs VT1-0-SR — frequently asked
Is VT1-0-SR stronger than VT1-0-ANN?
Yes. VT1-0-SR has a typical yield strength of 400 MPa (58 ksi) against 320 MPa (46.4 ksi) for VT1-0-ANN — about 25% more. Tensile strength is 500 MPa (72.5 ksi) vs 450 MPa (65.3 ksi).
Which condition does FabDigit quote by default, ANN or SR?
ANN is the default VT1-0 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 VT1-0-ANN over VT1-0-SR?
Pick VT1-0-ANN when the part is bent, formed or impact-loaded. Pick VT1-0-SR when strength drives the design.
