Titanium Grade 2H-ANN vs Grade 2H CW-SR
Titanium · Grade 2H temper comparison
Grade 2H-ANN and Grade 2H CW-SR are two conditions of the same titanium grade, Grade 2H: ANN (annealed) versus CW-SR (cold worked and stress relieved). The chemistry is identical, so every difference below comes from the condition. Grade 2H CW-SR is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 350 MPa (50.8 ksi) for Grade 2H-ANN, about 34% more; tensile strength follows at 560 MPa (81.2 ksi) vs 460 MPa (66.7 ksi). In exchange, Grade 2H-ANN is the more ductile: elongation 25% versus 15% for Grade 2H CW-SR, and Grade 2H CW-SR is harder (205 HB vs 160 HB). Grade 2H-ANN runs hotter in service (300°C vs 250°C continuous).
Grade 2H-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Grade 2H CW-SRChoose it when strength drives the design.
Grade 2H-ANN vs Grade 2H 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.

Grade 2H-ANN vs Grade 2H CW-SR — frequently asked
Is Grade 2H CW-SR stronger than Grade 2H-ANN?
Yes. Grade 2H CW-SR has a typical yield strength of 470 MPa (68.2 ksi) against 350 MPa (50.8 ksi) for Grade 2H-ANN — about 34% more. Tensile strength is 560 MPa (81.2 ksi) vs 460 MPa (66.7 ksi).
Which condition does FabDigit quote by default, ANN or CW-SR?
ANN is the default Grade 2H condition in the FabDigit quote flow. 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, Grade 2H-ANN or Grade 2H CW-SR?
Grade 2H CW-SR, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for Grade 2H-ANN.
