Titanium Ti-6Al-4V (AM, F2924)-AB vs Ti-6Al-4V (AM, F2924)-ANN

Titanium · Ti-6Al-4V (AM, F2924) temper comparison

Ti-6Al-4V (AM, F2924)-AB and Ti-6Al-4V (AM, F2924)-ANN are two conditions of the same titanium grade, Ti-6Al-4V (AM, F2924): AB (as built (as printed)) versus ANN (annealed). The chemistry is identical, so every difference below comes from the condition. Ti-6Al-4V (AM, F2924)-AB is the stronger of the two: yield strength 1,120 MPa (162 ksi) against 920 MPa (133 ksi) for Ti-6Al-4V (AM, F2924)-ANN, about 22% more; tensile strength follows at 1,250 MPa (181 ksi) vs 1,010 MPa (146 ksi). In exchange, Ti-6Al-4V (AM, F2924)-ANN is the more ductile: elongation 14% versus 7% for Ti-6Al-4V (AM, F2924)-AB, and Ti-6Al-4V (AM, F2924)-AB is harder (41 HRC vs 33 HRC).

Ti-6Al-4V (AM, F2924)-AB vs Ti-6Al-4V (AM, F2924)-ANN — frequently asked

Is Ti-6Al-4V (AM, F2924)-AB stronger than Ti-6Al-4V (AM, F2924)-ANN?

Yes. Ti-6Al-4V (AM, F2924)-AB has a typical yield strength of 1,120 MPa (162 ksi) against 920 MPa (133 ksi) for Ti-6Al-4V (AM, F2924)-ANN — about 22% more. Tensile strength is 1,250 MPa (181 ksi) vs 1,010 MPa (146 ksi).

Which condition does FabDigit quote by default, AB or ANN?

SR is the default Ti-6Al-4V (AM, F2924) condition in the FabDigit quote flow (neither AB nor ANN). 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-6Al-4V (AM, F2924)-AB or Ti-6Al-4V (AM, F2924)-ANN?

Ti-6Al-4V (AM, F2924)-ANN, by a small margin. Both rate poor for machinability — 20/100 against 15/100 for Ti-6Al-4V (AM, F2924)-AB.
