Titanium Ti Grade 2 CW-Hard vs Ti Grade 2-HR
Titanium · Ti Grade 2 temper comparison
Ti Grade 2 CW-Hard and Ti Grade 2-HR are two conditions of the same titanium grade, Ti Grade 2: CW-Hard (cold worked, as-rolled hard strip/foil) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. Ti Grade 2 CW-Hard is the stronger of the two: yield strength 630 MPa (91.4 ksi) against 370 MPa (53.7 ksi) for Ti Grade 2-HR, about 70% more; tensile strength follows at 700 MPa (102 ksi) vs 470 MPa (68.2 ksi). In exchange, Ti Grade 2-HR is the more ductile: elongation 22% versus 8% for Ti Grade 2 CW-Hard, and Ti Grade 2 CW-Hard is harder (230 HB vs 160 HB). Ti Grade 2-HR runs hotter in service (300°C vs 200°C continuous).
Ti Grade 2 CW-HardChoose it when strength drives the design.
Ti Grade 2-HRChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Ti Grade 2 CW-Hard 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 CW-Hard vs Ti Grade 2-HR — frequently asked
Is Ti Grade 2 CW-Hard stronger than Ti Grade 2-HR?
Yes. Ti Grade 2 CW-Hard has a typical yield strength of 630 MPa (91.4 ksi) against 370 MPa (53.7 ksi) for Ti Grade 2-HR — about 70% more. Tensile strength is 700 MPa (102 ksi) vs 470 MPa (68.2 ksi).
Which condition does FabDigit quote by default, CW-Hard or HR?
Annealed is the default Ti Grade 2 condition in the FabDigit quote flow (neither CW-Hard 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.
When should I choose Ti Grade 2 CW-Hard over Ti Grade 2-HR?
Pick Ti Grade 2 CW-Hard when strength drives the design. Pick Ti Grade 2-HR when the part is bent, formed or impact-loaded, or when the part sees heat.
