Titanium Grade 26 Annealed vs Grade 26 CW-SR
Titanium · Grade 26 temper comparison
Grade 26 Annealed and Grade 26 CW-SR are two conditions of the same titanium grade, Grade 26: Annealed versus CW-SR (cold worked and stress relieved). The chemistry is identical, so every difference below comes from the condition. Grade 26 CW-SR is the stronger of the two: yield strength 540 MPa (78.3 ksi) against 380 MPa (55.1 ksi) for Grade 26 Annealed, about 42% more; tensile strength follows at 620 MPa (89.9 ksi) vs 485 MPa (70.3 ksi). In exchange, Grade 26 Annealed is the more ductile: elongation 26% versus 18% for Grade 26 CW-SR, and Grade 26 CW-SR is harder (210 HB vs 160 HB). Grade 26 Annealed runs hotter in service (400°C vs 300°C continuous).
Grade 26 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Grade 26 CW-SRChoose it when strength drives the design.
Grade 26 Annealed vs Grade 26 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.

Grade 26 Annealed vs Grade 26 CW-SR — frequently asked
Is Grade 26 CW-SR stronger than Grade 26 Annealed?
Yes. Grade 26 CW-SR has a typical yield strength of 540 MPa (78.3 ksi) against 380 MPa (55.1 ksi) for Grade 26 Annealed — about 42% more. Tensile strength is 620 MPa (89.9 ksi) vs 485 MPa (70.3 ksi).
Which condition does FabDigit quote by default, Annealed or CW-SR?
Annealed is the default Grade 26 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, Grade 26 Annealed or Grade 26 CW-SR?
Grade 26 CW-SR, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for Grade 26 Annealed; for welding the order is Grade 26 Annealed first (excellent, 85/100) then Grade 26 CW-SR (very good, 78/100).
