Titanium Grade 23 vs Ti Grade 24
Titanium · grade comparison
Titanium Grade 23 and Ti Grade 24 are both titanium grades. Both yield at about 850 MPa — strength does not separate them. Ti Grade 24 is harder — 36 HRC against 33 HRC for Grade 23 — which matters for wear surfaces and threads. Ti Grade 24 runs hotter in service (400°C vs 350°C continuous). On the shop floor, Grade 23 welds better (80 vs 70 out of 100) and Grade 23 forms better (fair vs poor).
Grade 23Choose it when it will be welded.
Ti Grade 24Choose it when surface hardness matters, or when the part sees heat.
Grade 23 vs Ti Grade 24: 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 Ti Grade 24 — frequently asked
What is the difference between Grade 23 and Ti Grade 24?
Titanium Grade 23 and Ti Grade 24 are both titanium grades. Both yield at about 850 MPa — strength does not separate them. Ti Grade 24 is harder — 36 HRC against 33 HRC for Grade 23 — which matters for wear surfaces and threads.
Which is cheaper, Grade 23 or Ti Grade 24?
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 Ti Grade 24?
Grade 23. Its weldability rates very good (80/100) against very good (70/100) for Ti Grade 24.
