Titanium Ti Grade 17 Annealed vs Ti Grade 17 CW-SR
Titanium · Ti Grade 17 temper comparison
Ti Grade 17 Annealed and Ti Grade 17 CW-SR are two conditions of the same titanium grade, Ti Grade 17: Annealed versus CW-SR (cold worked and stress relieved). The chemistry is identical, so every difference below comes from the condition. Ti Grade 17 CW-SR is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 230 MPa (33.4 ksi) for Ti Grade 17 Annealed, about 65% more; tensile strength follows at 450 MPa (65.3 ksi) vs 330 MPa (47.9 ksi). In exchange, Ti Grade 17 Annealed is the more ductile: elongation 32% versus 18% for Ti Grade 17 CW-SR, and Ti Grade 17 CW-SR is harder (160 HB vs 120 HB).

Ti Grade 17 Annealed vs Ti Grade 17 CW-SR: 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 17 Annealed vs Ti Grade 17 CW-SR — frequently asked
Is Ti Grade 17 CW-SR stronger than Ti Grade 17 Annealed?
Yes. Ti Grade 17 CW-SR has a typical yield strength of 380 MPa (55.1 ksi) against 230 MPa (33.4 ksi) for Ti Grade 17 Annealed — about 65% more. Tensile strength is 450 MPa (65.3 ksi) vs 330 MPa (47.9 ksi).
Which condition does FabDigit quote by default, Annealed or CW-SR?
Annealed is the default Ti Grade 17 condition in the FabDigit quote flow. 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 is easier to machine, Ti Grade 17 Annealed or Ti Grade 17 CW-SR?
Ti Grade 17 CW-SR, by a small margin. Both rate fair for machinability — 45/100 against 38/100 for Ti Grade 17 Annealed; for welding the order is Ti Grade 17 Annealed first (excellent, 88/100) then Ti Grade 17 CW-SR (very good, 80/100).
