Titanium Ti Grade 29 BETA vs Ti Grade 29-STA
Titanium · Ti Grade 29 temper comparison
Ti Grade 29 BETA and Ti Grade 29-STA are two conditions of the same titanium grade, Ti Grade 29: BETA (transformed Beta) versus STA (solution treated and aged). The chemistry is identical, so every difference below comes from the condition. Ti Grade 29-STA is the stronger of the two: yield strength 930 MPa (135 ksi) against 830 MPa (120 ksi) for Ti Grade 29 BETA, about 12% more; tensile strength follows at 1,000 MPa (145 ksi) vs 910 MPa (132 ksi). Ti Grade 29-STA is harder — 350 HB against 320 HB for Ti Grade 29 BETA — which matters for wear surfaces and threads. Ti Grade 29 BETA runs hotter in service (400°C vs 315°C continuous).
Ti Grade 29 BETAChoose it when the part sees heat.
Ti Grade 29-STAChoose it when strength drives the design, or when surface hardness matters.
Ti Grade 29 BETA vs Ti Grade 29-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 Grade 29 BETA vs Ti Grade 29-STA — frequently asked
Is Ti Grade 29-STA stronger than Ti Grade 29 BETA?
Yes. Ti Grade 29-STA has a typical yield strength of 930 MPa (135 ksi) against 830 MPa (120 ksi) for Ti Grade 29 BETA — about 12% more. Tensile strength is 1,000 MPa (145 ksi) vs 910 MPa (132 ksi).
Which condition does FabDigit quote by default, BETA or STA?
Annealed is the default Ti Grade 29 condition in the FabDigit quote flow (neither BETA 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 welds better, Ti Grade 29 BETA or Ti Grade 29-STA?
Ti Grade 29-STA. Its weldability rates very good (80/100) against very good (72/100) for Ti Grade 29 BETA.
