Titanium Grade 2-AW vs Grade 2-SR
Titanium · Grade 2 temper comparison
Grade 2-AW and Grade 2-SR are two conditions of the same titanium grade, Grade 2: AW (as-welded deposit) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. Grade 2-SR is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 370 MPa (53.7 ksi) for Grade 2-AW, about 22% more; tensile strength follows at 520 MPa (75.4 ksi) vs 450 MPa (65.3 ksi). Grade 2-SR is the more ductile: elongation 20% versus 18% for Grade 2-AW.
Grade 2-SRChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Grade 2-AW vs Grade 2-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 2-AW vs Grade 2-SR — frequently asked
Is Grade 2-SR stronger than Grade 2-AW?
Yes. Grade 2-SR has a typical yield strength of 450 MPa (65.3 ksi) against 370 MPa (53.7 ksi) for Grade 2-AW — about 22% more. Tensile strength is 520 MPa (75.4 ksi) vs 450 MPa (65.3 ksi).
Which condition does FabDigit quote by default, AW or SR?
O is the default Grade 2 condition in the FabDigit quote flow (neither AW nor SR). 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 2-AW or Grade 2-SR?
Grade 2-SR, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for Grade 2-AW; for welding the order is Grade 2-AW first (excellent, 90/100) then Grade 2-SR (excellent, 85/100).
