Titanium Ti Grade 33 Annealed vs Ti Grade 33 CW-SR
Titanium · Ti Grade 33 temper comparison
Ti Grade 33 Annealed and Ti Grade 33 CW-SR are two conditions of the same titanium grade, Ti Grade 33: Annealed versus CW-SR (cold worked and stress relieved). The chemistry is identical, so every difference below comes from the condition. Ti Grade 33 CW-SR is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 320 MPa (46.4 ksi) for Ti Grade 33 Annealed, about 50% more; tensile strength follows at 560 MPa (81.2 ksi) vs 420 MPa (60.9 ksi). In exchange, Ti Grade 33 Annealed is the more ductile: elongation 25% versus 16% for Ti Grade 33 CW-SR, and Ti Grade 33 CW-SR is harder (200 HB vs 160 HB).

Ti Grade 33 Annealed vs Ti Grade 33 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.
