Titanium Ti Grade 2 CWSR vs Ti Grade 2-HR
Titanium · Ti Grade 2 temper comparison
Ti Grade 2 CWSR and Ti Grade 2-HR are two conditions of the same titanium grade, Ti Grade 2: CWSR (cold worked and stress relieved bar / tube) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. Ti Grade 2 CWSR is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 370 MPa (53.7 ksi) for Ti Grade 2-HR, about 49% more; tensile strength follows at 620 MPa (89.9 ksi) vs 470 MPa (68.2 ksi). In exchange, Ti Grade 2-HR is the more ductile: elongation 22% versus 15% for Ti Grade 2 CWSR, and Ti Grade 2 CWSR is harder (200 HB vs 160 HB).
Ti Grade 2 CWSRChoose it when strength drives the design.
Ti Grade 2-HRChoose it when the part is bent, formed or impact-loaded.
Ti Grade 2 CWSR vs Ti Grade 2-HR: 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 2 CWSR vs Ti Grade 2-HR — frequently asked
Is Ti Grade 2 CWSR stronger than Ti Grade 2-HR?
Yes. Ti Grade 2 CWSR has a typical yield strength of 550 MPa (79.8 ksi) against 370 MPa (53.7 ksi) for Ti Grade 2-HR — about 49% more. Tensile strength is 620 MPa (89.9 ksi) vs 470 MPa (68.2 ksi).
Which condition does FabDigit quote by default, CWSR or HR?
Annealed is the default Ti Grade 2 condition in the FabDigit quote flow (neither CWSR nor HR). 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 2 CWSR or Ti Grade 2-HR?
Ti Grade 2 CWSR. Its machinability rates fair (38/100) against poor (30/100) for Ti Grade 2-HR.
