Titanium Grade 13 Annealed vs Grade 13 CWSR
Titanium · Grade 13 temper comparison
Grade 13 Annealed and Grade 13 CWSR are two conditions of the same titanium grade, Grade 13: Annealed versus CWSR (cold worked and stress relieved). The chemistry is identical, so every difference below comes from the condition. Grade 13 CWSR is the stronger of the two: yield strength 390 MPa (56.6 ksi) against 240 MPa (34.8 ksi) for Grade 13 Annealed, about 63% more; tensile strength follows at 480 MPa (69.6 ksi) vs 345 MPa (50 ksi). In exchange, Grade 13 Annealed is the more ductile: elongation 28% versus 18% for Grade 13 CWSR, and Grade 13 CWSR is harder (175 HB vs 130 HB). Grade 13 Annealed runs hotter in service (300°C vs 250°C continuous).
Grade 13 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Grade 13 CWSRChoose it when strength drives the design.
Grade 13 Annealed vs Grade 13 CWSR: 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.
