Titanium Ti Grade 37 Annealed vs Ti Grade 37 CWSR
Titanium · Ti Grade 37 temper comparison
Ti Grade 37 Annealed and Ti Grade 37 CWSR are two conditions of the same titanium grade, Ti Grade 37: Annealed versus CWSR (cold Worked + Stress Relieved). The chemistry is identical, so every difference below comes from the condition. Ti Grade 37 CWSR is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 350 MPa (50.8 ksi) for Ti Grade 37 Annealed, about 37% more; tensile strength follows at 550 MPa (79.8 ksi) vs 450 MPa (65.3 ksi). In exchange, Ti Grade 37 Annealed is the more ductile: elongation 25% versus 15% for Ti Grade 37 CWSR, and Ti Grade 37 CWSR is harder (205 HB vs 170 HB). Ti Grade 37 Annealed runs hotter in service (300°C vs 250°C continuous).
Ti Grade 37 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Ti Grade 37 CWSRChoose it when strength drives the design.
Ti Grade 37 Annealed vs Ti Grade 37 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.
