Titanium Ti Grade 13 Annealed vs Ti Grade 13 CW-SR
Titanium · Ti Grade 13 temper comparison
Ti Grade 13 Annealed and Ti Grade 13 CW-SR are two conditions of the same titanium grade, Ti Grade 13: Annealed versus CW-SR (cold Worked and Stress Relieved). The chemistry is identical, so every difference below comes from the condition. Ti Grade 13 CW-SR is the stronger of the two: yield strength 400 MPa (58 ksi) against 210 MPa (30.5 ksi) for Ti Grade 13 Annealed, about 90% more; tensile strength follows at 480 MPa (69.6 ksi) vs 320 MPa (46.4 ksi). In exchange, Ti Grade 13 Annealed is the more ductile: elongation 30% versus 15% for Ti Grade 13 CW-SR, and Ti Grade 13 CW-SR is harder (175 HB vs 120 HB). Ti Grade 13 Annealed runs hotter in service (300°C vs 250°C continuous).
Ti Grade 13 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Ti Grade 13 CW-SRChoose it when strength drives the design.
Ti Grade 13 Annealed vs Ti Grade 13 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 13 Annealed vs Ti Grade 13 CW-SR — frequently asked
Is Ti Grade 13 CW-SR stronger than Ti Grade 13 Annealed?
Yes. Ti Grade 13 CW-SR has a typical yield strength of 400 MPa (58 ksi) against 210 MPa (30.5 ksi) for Ti Grade 13 Annealed — about 90% more. Tensile strength is 480 MPa (69.6 ksi) vs 320 MPa (46.4 ksi).
Which condition does FabDigit quote by default, Annealed or CW-SR?
Annealed is the default Ti Grade 13 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 13 Annealed or Ti Grade 13 CW-SR?
Ti Grade 13 CW-SR, by a small margin. Both rate fair for machinability — 45/100 against 38/100 for Ti Grade 13 Annealed; for welding the order is Ti Grade 13 Annealed first (excellent, 88/100) then Ti Grade 13 CW-SR (very good, 80/100).
