Titanium Grade 23 vs SP-700
Titanium · grade comparison
Titanium Grade 23 and SP-700 are both titanium grades. Both yield at about 850 MPa — strength does not separate them. SP-700 is the more ductile: elongation 17% versus 15% for Grade 23, and Grade 23 is harder (320 HB vs 300 HB). On the shop floor, Grade 23 welds better (very good vs good).
Grade 23Choose it when it will be welded.
SP-700Choose it when the part is bent, formed or impact-loaded.
Grade 23 vs SP-700: 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 SP-700 — frequently asked
What is the difference between Grade 23 and SP-700?
Titanium Grade 23 and SP-700 are both titanium grades. Both yield at about 850 MPa — strength does not separate them. SP-700 is the more ductile: elongation 17% versus 15% for Grade 23, and Grade 23 is harder (320 HB vs 300 HB).
Which is cheaper, Grade 23 or SP-700?
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 SP-700?
Grade 23. Its weldability rates very good (80/100) against good (65/100) for SP-700.
