Titanium Ti Grade 30 Annealed vs Ti Grade 30 CW-SR
Titanium · Ti Grade 30 temper comparison
Ti Grade 30 Annealed and Ti Grade 30 CW-SR are two conditions of the same titanium grade, Ti Grade 30: Annealed versus CW-SR (cold worked and stress relieved). The chemistry is identical, so every difference below comes from the condition. Ti Grade 30 CW-SR is the stronger of the two: yield strength 540 MPa (78.3 ksi) against 330 MPa (47.9 ksi) for Ti Grade 30 Annealed, about 64% more; tensile strength follows at 620 MPa (89.9 ksi) vs 440 MPa (63.8 ksi). In exchange, Ti Grade 30 Annealed is the more ductile: elongation 28% versus 15% for Ti Grade 30 CW-SR, and Ti Grade 30 CW-SR is harder (210 HB vs 160 HB). Ti Grade 30 Annealed runs hotter in service (300°C vs 250°C continuous).
Ti Grade 30 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Ti Grade 30 CW-SRChoose it when strength drives the design.
Ti Grade 30 Annealed vs Ti Grade 30 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 30 Annealed vs Ti Grade 30 CW-SR — frequently asked
Is Ti Grade 30 CW-SR stronger than Ti Grade 30 Annealed?
Yes. Ti Grade 30 CW-SR has a typical yield strength of 540 MPa (78.3 ksi) against 330 MPa (47.9 ksi) for Ti Grade 30 Annealed — about 64% more. Tensile strength is 620 MPa (89.9 ksi) vs 440 MPa (63.8 ksi).
Which condition does FabDigit quote by default, Annealed or CW-SR?
Annealed is the default Ti Grade 30 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 30 Annealed or Ti Grade 30 CW-SR?
Ti Grade 30 CW-SR, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for Ti Grade 30 Annealed; for welding the order is Ti Grade 30 Annealed first (excellent, 85/100) then Ti Grade 30 CW-SR (very good, 80/100).
