Titanium Ti Grade 24 CWSR vs Ti Grade 24-STA
Titanium · Ti Grade 24 temper comparison
Ti Grade 24 CWSR and Ti Grade 24-STA are two conditions of the same titanium grade, Ti Grade 24: CWSR (cold Worked & Stress Relieved) versus STA (solution treated and aged). The chemistry is identical, so every difference below comes from the condition. Ti Grade 24-STA is the stronger of the two: yield strength 1,035 MPa (150 ksi) against 980 MPa (142 ksi) for Ti Grade 24 CWSR, about 6% more. Ti Grade 24 CWSR is harder — 352 HB against 334 HB for Ti Grade 24-STA — which matters for wear surfaces and threads. On the shop floor, Ti Grade 24 CWSR welds better (good vs fair).
Ti Grade 24 CWSRChoose it when surface hardness matters, or when it will be welded.
Ti Grade 24-STAChoose it when strength drives the design.
Ti Grade 24 CWSR vs Ti Grade 24-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 24 CWSR vs Ti Grade 24-STA — frequently asked
Is Ti Grade 24-STA stronger than Ti Grade 24 CWSR?
Yes. Ti Grade 24-STA has a typical yield strength of 1,035 MPa (150 ksi) against 980 MPa (142 ksi) for Ti Grade 24 CWSR — about 6% more. Tensile strength is 1,105 MPa (160 ksi) vs 1,050 MPa (152 ksi).
Which condition does FabDigit quote by default, CWSR or STA?
Annealed is the default Ti Grade 24 condition in the FabDigit quote flow (neither CWSR 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 24 CWSR or Ti Grade 24-STA?
Ti Grade 24 CWSR. Its weldability rates good (62/100) against fair (50/100) for Ti Grade 24-STA.
