Titanium Grade 23 vs VT3-1
Titanium · grade comparison
Titanium Grade 23 and VT3-1 are both titanium grades. VT3-1 is the stronger of the two: yield strength 950 MPa (138 ksi) against 850 MPa (123 ksi) for Grade 23, about 12% more; tensile strength follows at 1,050 MPa (152 ksi) vs 930 MPa (135 ksi). In exchange, Grade 23 is the more ductile: elongation 15% versus 13% for VT3-1. VT3-1 runs hotter in service (450°C vs 350°C continuous) and VT3-1 conducts heat better (8 W/m·K vs 6.7 W/m·K). On the shop floor, Grade 23 welds better (very good vs fair).
Grade 23Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
VT3-1Choose it when strength drives the design, or when the part sees heat.
Grade 23 vs VT3-1: 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 vs VT3-1 — frequently asked
Is VT3-1 stronger than Grade 23?
Yes. VT3-1 has a typical yield strength of 950 MPa (138 ksi) against 850 MPa (123 ksi) for Grade 23 — about 12% more. Tensile strength is 1,050 MPa (152 ksi) vs 930 MPa (135 ksi).
Which is cheaper, Grade 23 or VT3-1?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, Grade 23 or VT3-1?
Grade 23. Its weldability rates very good (80/100) against fair (45/100) for VT3-1.
