Titanium Ti Grade 36 Annealed vs Ti Grade 36-CW
Titanium · Ti Grade 36 temper comparison
Ti Grade 36 Annealed and Ti Grade 36-CW are two conditions of the same titanium grade, Ti Grade 36: Annealed versus CW (cold worked). The chemistry is identical, so every difference below comes from the condition. Ti Grade 36-CW is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 340 MPa (49.3 ksi) for Ti Grade 36 Annealed, about 65% more; tensile strength follows at 620 MPa (89.9 ksi) vs 420 MPa (60.9 ksi). In exchange, Ti Grade 36 Annealed is the more ductile: elongation 25% versus 12% for Ti Grade 36-CW, and Ti Grade 36-CW is harder (200 HB vs 138 HB). Ti Grade 36 Annealed runs hotter in service (300°C vs 250°C continuous). On the shop floor, Ti Grade 36 Annealed welds better (80 vs 70 out of 100).
Ti Grade 36 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Ti Grade 36-CWChoose it when strength drives the design.
Ti Grade 36 Annealed vs Ti Grade 36-CW: 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 36 Annealed vs Ti Grade 36-CW — frequently asked
Is Ti Grade 36-CW stronger than Ti Grade 36 Annealed?
Yes. Ti Grade 36-CW has a typical yield strength of 560 MPa (81.2 ksi) against 340 MPa (49.3 ksi) for Ti Grade 36 Annealed — about 65% more. Tensile strength is 620 MPa (89.9 ksi) vs 420 MPa (60.9 ksi).
Which condition does FabDigit quote by default, Annealed or CW?
Annealed is the default Ti Grade 36 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 36 Annealed or Ti Grade 36-CW?
Ti Grade 36-CW, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for Ti Grade 36 Annealed; for welding the order is Ti Grade 36 Annealed first (very good, 80/100) then Ti Grade 36-CW (very good, 70/100).
